Association and path analysis studies for yield contributing and fibre quality traits in the F1 population of Gossypium hirsutum L.

The present investigation on correlation and path analysis studies helps to study the relationship among the yield and yield contributing traits along with the quality parameters. The observations were taken in the F1 population of 35 hybrids along with lines (7 lines) and testers (5 testers) for the traits viz. plant height (cm), number of sympodial branches per plant, the number of bolls per plant, boll weight (g), lint index (g), single cotton yield per plant (g), ginning outturn (%), upper half mean length (cm), elongation percent (%) and micronaire value (µg per inch). The results revealed that seed cotton yield per plant had strong and positive association with the traits namely number of sympodial branches per plant (0.646), number of bolls (0.633) and boll weight (0.652). Path analysis study revealed that number of sympodial branches per plant (1.5396), boll weight (0.6285), lint index (1.3526) and upper half mean length (0.3392) had high direct positive effects on single plant yield and indirect very high positive effects through the traits viz., number of sympodial branches per plant via., number of bolls per plant (1.5125) and boll weight (1.0121). Hence selection based on these traits that are positively associated and direct positive effect with the yield would produce the best outcome in the genotypes in further breeding programmes.

Heterosis and combining ability of iron, zinc and their bioavailability in maize inbred lines under low nitrogen and optimal environments

Iron (Fe) and zinc (Zn) nutrient enrichment of staple crops through biofortification can contribute to alleviating micronutrient deficiency in sub-Saharan Africa. A line × tester mating design was used to determine the general combining ability (GCA), specific combining ability (SCA) and heterosis for grain yield, iron, Zn and phytic concentration of six lines crossed with three testers. Lines and testers were selected for high, intermediate and low mineral content. The F1 hybrids and parental lines were evaluated under low nitrogen (N) and optimum conditions across four environments over two seasons. Under low N conditions, Fe and Zn concentration in grain, and grain yield of genotypes were reduced by 9%, 9%, and 59%, respectively. However, phytic acid concentration in grain was increased by 10% under low N conditions. Both additive and non-additive gene effects were important in controlling Fe, Zn and phytic acid concentration in grain and grain yield of maize under both N conditions. The preponderance of GCA effects indicates the importance of additive gene effects in the inheritance of grain yield. Line GCA effects were more sensitive to N conditions across the environments than the tester GCA. High and significant positive SCA effects for grain yield, Fe and Zn content under low N conditions, would be a good indicator of possible heterosis in these traits. Hybrid CBY101 LM-1600 × CBY358 LM-1857 had high and significant positive SCA for grain yield under low N conditions and is a promising candidate for production in low N environments. CBY358 LM-1857 (tester) and CBY102 LM-1601 (line) are a good general combiners for Fe, Zn and GY can be used as parents in future maize hybrid breeding programs to develop high-yielding maize genotypes with high Fe and Zn content.

GENOTYPES AND STORAGE DURATION EFFECTS ON THE QUALITY OF CUT FLOWER – GERBERA (GERBERA JAMESONII HOOK)

Studies on cut flowers have occurred, for improving their quality is the main priority. One of the top 10 cut flowers in the world, the gerbera, or Transvaal daisy (Gerbera jamesonii Hook), is a flowering plant. The presented study aimed to investigate the effect of genotypes, storage duration, and their interactions on the quality of cut flower – Transvaal daisy. Two cultivars of Gerbera (sweet smile and sweet surprise) and their four storage durations underwent examination on the various parameters of vase life and carbohydrates. The results exhibited that the cultivar ‘Sweet smile’ had exceptional values of the studied parameters compared with the cultivar ‘Sweet surprise.’ The treatment of seven days with dry-cool storage proved superior upon 14- and 21-day treatments (11.71, 11.05, and 5.94, respectively) and had the highest positive effects on vase life and flower carbohydrate content compared with the other two storage treatments. The treatment of zero days (non-stored flowers) was significantly superior to seven-day storage. The interactions of cultivars and storage durations gave the highest effect in reducing the depletion of the carbohydrates content in cultivars with zero days, increasing the flower’s vase life. Therefore, the highest values recorded for the cultivar Sweet smile are zero days, followed by seven days of storage, compared with the rest of the treatments.

Public willingness to support the policy of banning gasoline vehicles sales and its internal mechanism

Implementation of the banning gasoline vehicles sales policy (BGVSP) will help China achieve its dual carbon goal, but it will harm consumers’ rights of choice. Thus, we used grounded theory, a questionnaire survey, and structural equation modeling to build a theoretical motivation model of the public willingness to support (PWTS). Based on 1371 questionnaires, we verified the core influencing factors and mechanisms of the PWTS. The main results are as follows. (1) Because of their different motives, the PWTS can result from three reasons, i.e., decision-making, interpersonal, and civic, in which the proportion of civic awareness is higher. (2) Among individual factors, an environmentally oriented lifestyle and preference for environmental protection have a higher positive effect on the improvement of support intention, but for interpersonal support intention, the effect of economic preference is more significant. (3) The mediating role and effect of psychological factors among the individual factors are quite different. The indirect effect of values and public awareness is higher. (4) The product factors related to new energy vehicles are external moderator variables that affect the PWTS, which play negative effects in the role of preference factors. Hence, from a micro perspective, this study has improved the research scope around the BGVSP, and also contributed feasible recommendations to promote the implementation of the ban.

Corporate website as a strategic resource: Comparative analysis of Russian and European companies

The paper investigates the mechanisms through which companies can gain additional competitive advantages through using a corporate website. We identified statistically significant relationship between financial performance and aggregated metrics of the corporate website based on sample of 1240 European and 1056 Russian companies. The study is implemented in two stages: (1) applying the principal component analysis to conceptualize website metrics and (2) evaluating a regression model with a dummy variable to analyze the relationship between the characteristics of corporate websites and the financial performance of companies. Principal Component Analysis identified two components that reflect the visibility and authority of corporate websites. Regression analysis showed a statistically significant relationship between these characteristics and the company’s revenue. Moreover, for Russian companies we observe that visibility of the company’s website has the highest positive effect on the revenue. On contrary, for European companies’ website’s authority provides the highest increase in its revenue.

Differential effects of UPPS-P impulsivity on subjective alcohol response and craving: An experimental test of acquired preparedness.

Recent studies have extended the acquired preparedness model to experimental data, finding that impulsivity predicts subjective alcohol response, a related yet distinct construct from expectancies. However, studies have not tested whether specific facets of impulsivity predict subjective response, or whether impulsivity indirectly predicts alcohol craving through subjective response. Young adults who reported past-month binge drinking (N = 448) participated in a placebo-controlled alcohol administration study. Mediation models tested whether UPPS-P impulsivity facets indirectly predicted alcohol craving through subjective response on the ascending and descending limbs of the blood alcohol content (BAC). High arousal positive (e.g., sociable), low arousal positive (e.g., relaxed), high arousal negative (e.g., rude), and low arousal negative (e.g., dizzy) subjective effects were measured across limbs. Moderation by beverage condition was not detected, so models were collapsed across beverage condition. Sensation seeking indirectly predicted craving through high arousal positive subjective response on both limbs, whereas positive and negative urgency directly predicted craving. When controlling for baseline subjective response and craving, effects of sensation seeking and negative urgency on subjective response and craving became nonsignificant. The effects of positive urgency on craving remained, and an effect of positive urgency on high arousal positive effects emerged on the ascending limb. Findings suggest that relations among impulsivity, subjective response, and craving are contingent upon the specific facet of impulsivity. Interventions targeting predrink cue exposure and/or positive emotionality may be most effective for sensation seekers, whereas targeting subjective response and/or expectancies may be most efficacious for individuals high in positive urgency.

Correlation and Path Analysis of Okra (Abelmoschus esculentus L. Monech) Germplasms for Fruit Yield and its Components

Field experiment was conducted at AICRP on Vegetable Crops of OUAT, Bhubaneswar during Kharif, 2018-19 to study the correlation of okra germplasm. Study on correlation between several characters shows that selection for fruit yield based on plant height, stem diameter, nodes plant-1, leaflet length, average fruit weight, fruit length, fruit girth, days to 1st flowering, days to 50% flowering, number of fruits plant-1, PDI at 30DAS, PDI at 45DAS, PDI at 60DAS, PDI at 75DAS. In present study genotypic correlation was observed to be higher than the corresponding phenotypic correlations for all the character combinations and therefore it shows that the suppression of phenotypic expression under the influence of environmental factors. Path coefficient analysis of total fruit yield contributing attributes estimated that like average fruit weight had the highest positive effects followed by number of fruits plant-1, days to 1st flowering, plant height, PDI for YVMV at 60 DAS, stem diameter, node at 1st flowering, nodes plant-1, which indicated that these traits have to give much importance in selection programme for yield improvement in okra.

Green Innovation in Regional Logistics: Level Evaluation and Spatial Analysis

Green innovation is imperative for the high-quality and sustainable development of the modern logistics industry. It is also key for achieving the goals of peak emissions and carbon neutrality. This study provides a way of thinking about the evaluation of the green innovation level of the logistics industry. The variance inflation factor-variance coefficient method was employed to construct an evaluation index system of the regional logistics green innovation level (RLGIL) from three dimensions. Empirical data were collected from statistical yearbooks covering 30 provinces in China from 2013 to 2017. Thereafter, the combination weighting-based GRA-TOPSIS method was applied to evaluate the RLGIL, and the spatial distribution differences and spatiotemporal evolution characteristics of inter-provincial green innovation levels were analyzed. The RLGILs in the 30 provinces were found to be generally unbalanced, and the differences between the eastern and western regions were significant. Guangdong, Jiangsu, and Zhejiang had stronger RLGILs, whereas most other provinces did not reach the average level. The RLGIL of the 30 provinces had a high positive spatial correlation and spatial aggregating effect. From a national perspective, the values for the RLGIL were generally higher in the eastern and southern regions and lower in the western and northern regions. Although significant differences were found in the RLGIL of these provinces, the overall development trend was stable.

Assessment of genetic variability, correlation and path analysis in sesame (Sesamum indicum L.)

The present study was attempted with thirty-eight genotypes including three checks(GT-10, TKG-22, JTS-08). The experiment was carried out in randomized block design in three replications to evaluate variability, association between various economic traits, direct and indirect effect of different characters on yield. The observations were recorded for days to 50 percent flowering, productive branches, plant height (cm), height of 1st capsule bearing node (cm), number of capsules per plant, number of seeds per capsule, capsule length(cm), inter node length (cm), days to maturity, 1000-grain weight (g), percentage of oil and yield (g/plant). Analysis of variance revealed significant differences among the genotypes for all the characters. The magnitude of phenotypic coefficient of variance (PCV) and genotypic coefficient of variance (GCV) was larger for yield, number of productive branches, height of first capsule bearing node and number of capsule/plant and inter-node length. Genetic advance as per cent of mean for yield, number of productive branches, height of first capsule bearing node, number of capsules per plant and internode length were higher in sesame genotype. Correlation coefficient exhibited significant and high positive correlation for number of productive branches, number of capsules per plant and number of seeds per capsule and maturity. Path analysis indicated that the trait number of seeds per capsule, number of productive branches and number of capsules per plant had high direct positive effect on grain yield. These traits to be given due importance in the sesame improvement programme.

Suppression of Fusarium Wilt of Chickpea by Bacillus spp., Pseudomonas sp. and Rhizobacterial Isolate

This experiment was conducted to evaluate the antagonistic effects of some selected rhizobacteria on Fusarium oxysporium f. sp. ciceris in a pot experiment. Rhizobacterial isolates (one isolate of Pseudomonas, eight isolates of Bacillus genera and one bacterium isolate) and two chickpea cultivars (Shendi and Burgeig) were arranged in a factorial pot experiment in CRD with four replicates. The disease incidence and severity were detected weekly. Disease reduction percentage was estimated at the end of the study. Generally, the application of rhizobacterial isolates as biological control agent reduced disease incidence compared with the control in both cultivars. The incidence in cultivar Shendi occurred at the third week after inoculation when treated with Pseudomonas stutzeri strain W28 (SA3) and Bacillus subtilis strain CM14(SA9). For the two cultivars, Shendi and Burgeig, the Geobacillus sp. CRRI-HN-1(SA2) and Bacillus sp (SA1), respectively had the highest positive effect on disease incidence and severity throughout the experiment compared with the control. These were 45.36 and 44.82% in incidence; 55.36 and 63.89% in severity, respectively.

Estimation of path coefficient analysis for some quantitative traits in Rice ( Oryza sativa L.) genotypes

A field experiment was conducted at the Al Mushkab Rice Research Station (AMRR), Najaf, Iraq, during the rice growing season of 2018-2019 in Randomized Complete Block Design (RCBD) for the aim of estimating the path coefficient in 15 introduced and local genotypes of rice. The path coefficient was estimated for the number of days from planting to 50% flowering, the number of days from flowering to physiological maturity, plant height, leaf area index, number of branches/panicle, number of panicles / m2, number of grains/panicles, infertility percentage (sterility %), 1000 grains weight (gm), biological yield (kg. ha -1) and harvest index (HI %) with grain yield kg, ha. -1. The results of the study concluded that the trait of harvest index is an effective selection criterion for improving Rice grain yield because it achieved the highest overall positive effect, i.e., the highest positive genotypic correlation amounted to 0.761, and this trait also achieved a high direct positive effect on grain yield amounted to 0.83833.

Prospective Randomized Controlled Trial Comparing Laparoscopic Palomo Surgery versus Scrotal Antegrade Sclerotherapy in Adolescent Varicocele.

Varicocele is a common condition in adolescence and the most common correctable cause of infertility. This study aimed to analyze and compare the outcomes of scrotal antegrade sclerotherapy (SAS) and laparoscopic Palomo surgery (LPS) in a tertiary referral centre. Patients with left grade 3 varicocele indicated for surgery were prospectively enrolled and randomly allocated to the SAS and LPS groups, with their respective contralateral normal testes taken as controls. The primary outcome measures were clinical varicocele recurrence, testicular catch-up growth, and post-operative hydrocele. All patients were evaluated clinically and using Doppler ultrasound by radiologists. From 2015 to 2020, 113 patients completed the study and were statistically analyzed (SAS, n = 57; LPS, n = 56). All patients had significantly smaller testes pre-operatively that the testicular volume differences with control testes were -23% in SAS and -19% in LPS. At 12-month follow-up, there were no statistical significant difference in clinical recurrences between the 2 groups (SAS = 5.3% vs LPS = 5.4%, P>.05, non-inferiority test). Testicular catch-up growths were observed in both groups, the mean testicular volume difference between the treatment and control testes reduced from -23% to -8.1% in SAS (P<.001) and -19% to -9.3% in LPS (P<.001) at 12-month follow-up. There was no post-operative hydrocele in SAS compared to 7 in LPS (0% vs 13%, P = .006). Both SAS and LPS are safe and effective procedures for treatment of adolescent varicocele with significant positive effect on testicular catch-up growth. SAS is not inferior to LPS in terms of clinical recurrence rate and with significantly less post-operative hydrocele.

Achieving a high positive temperature coefficient effect at low temperature through combining spherical HDPE/SBR with MCMB

A novel system by using spherical high-density polyethylene (HDPE) and meso-carbon microbeads (MCMB) to regulate the positive temperature coefficient (PTC) effect is studied, and the elastic styrene-butadiene rubber (SBR) is used as the matrix. This HDPE-MCMB/SBR composite (HMSC) is constructed by a simple solution mixing method. The PTC intensity (PTCI) of HMSC with 1 wt% MCMB (HMSC-1) achieves three orders of magnitude (its value is 3.39) in the low-temperature range (20 °C to 90 °C), and HMSC-1 also shows fantastic PTCI reproducibility during the repeated temperature cycles from −20 °C to 90 °C. The high PTC effect is mainly caused by the collaborative combination of the expansion effect of HDPE spheres and the elasticity of SBR. The excellent stability during the temperature cycle mainly stems from the elastic effect of composite, rather than being destroyed during the temperature cycle. Meanwhile, HMSC-1 has good mechanical properties.

Улучшение посевных качеств семян гибрида подсолнечника Сурус в результате применения комплекса агротехнических приемов на участке гибридизации

When organizing seed production of new sunflower hybrids, there is a need to develop agronomic practices aimed at increasing the volume of production and quality of seeds. The work is focused on the study of opportunities to improve the sowing and yield qualities of the seeds of an interline sunflower hybrid Surus and the development of a set of agronomic practices implementing this improvement for their use at hybridization plots. The research was carried out in two stages. The first one was conducted in 2021 at the hybridization plot. We studied the effect of different agronomic practices (seeding rate, the use of fertilizers, crop protection chemicals and biological preparations against diseases and pests) on improving the sowing and yield properties of the seeds formed on the plants of the female parent of sunflower hybrid (CMS VK1-sur A). We found that the sowing of seeds of the parental forms of Surus at the hybridization plot with the complex of fertilizers (N23P60K60 at sowing and foliar application of microfertilizers Biostim maslichny (1.0 l/ha) + Ultramag bor (0.5 l/ha) at the stage of 6-8 true leaves and budding) has the highest positive effect on the mass of seeds in the head. The second stage was carried out in 2022 to determine the effect of agrotechnical backgrounds used at the hybridization plot on the biological properties of seeds (laboratory and field germination of seeds) formed in 2021. We established that the biological properties of the seeds formed at the hybridization plot of the hybrid Surus differed to some extent between individual indicators, and by variants of experiment. We noted high field germination (2–13 % higher than in other variants of the experiment) under application of biological plant protection against pests and diseases with microbiological fertilizers at the hybridization plot. The increase in field germination allowed reducing losses in the formation of scientifically justified plant density of the hybrid Surus.

Analyzing housing price determinants in Izmir using spatial models

The vast majority of the studies on house price dynamics focus on either structural/locational/demographic variables in a cross-sectional setting (i.e., hedonic price modeling) or on the impact of macroeconomic fundamentals in a time series framework. In this work, we argue that both approaches fall short of providing adequate information as cross-sectional analyses largely ignore the macro-dynamics, whereas time series approaches fail to incorporate the cross-sectional dimension. Current work combines both dimensions in a panel framework and provides, in this way, a methodological contribution as well as more informative analyses as it captures the impact of a wide array of variables. Thus, this study examines the housing prices in Izmir/Turkey by adopting the above-mentioned dimensions with both panel and spatial panel regressions. The study area consists of 212 neighborhoods located in different districts of Izmir. The period of analysis covers 30 months between 2017 and 2019. As an outcome of the empirical analyses, both structural/demographic, and macroeconomic variables were found evidently important. Hence, it is understood that all dimensions (structural/locational/demographic, macroeconomic) should be incorporated into comprehensive modeling. A high spatial dependence and positive spatial spillover effects were also detected.

Anaerobic Digestion of Chicken Manure Assisted by Carbon Nanotubes: Promotion of Volatile Fatty Acids Consumption and Methane Production

In this study, the effect of different concentrations of carbon nanotubes (Taunit-M; 0.5–6.5 g L−1) on the efficiency of anaerobic digestion of chicken manure is investigated. The highest positive effect on the specific production of methane is obtained when 5.0 g L−1 of carbon nanotubes are added to the anaerobic reactors. In addition, carbon nanotubes at these concentrations stimulate the biodegradation of volatile fatty acids, mainly acetate, butyrate, and finally propionate. The maximum production rate of methane increases by 15–16% in the presence of carbon nanotubes (5.0–6.5 g L−1). Also, addition of carbon nanotubes at certain concentrations increases total methane production. Finally, the addition of carbon nanotubes to the anaerobic reactors is found to the favor consumption of volatile fatty acids and improve the methane production kinetics and productivity during the anaerobic digestion of chicken manure.

Assessment of flax and hemp fibres in terms of their impact on the growth performance and health status of weaned piglets

Weaning is a critical phase in intensive piglet production marked by the frequent occurrence of digestive disorders posing health and economic burden. To stave off such weaning-related problems, antibiotics and supplements containing high levels of ZnO are often used. In this study, we investigated whether natural fibres obtained from two plants known for their dietary fibre profile and antioxidant properties: flax (Linum usitatissimum L.) and hemp (Cannabis sativa L.), can serve as a health-promoting diet supplement. The study was conducted on a total of 191 Polish Large White piglets from 18 L, from their birth to 56 days of age. Piglets were divided by litters into six groups: W1.5, F1.5, H1.5, W2.0, F2.0, and H2.0. Groups W1.5, F1.5, and H1.5 received feed supplemented with 1.5% fibre from wood cellulose (W), flax (F), and hemp (H), respectively, while groups W2.0, F2.0, and H2.0 received feed with a higher 2.0% content of the same fibres. Flax and hemp fibres were characterised by a complex composition, antioxidant properties due to the presence of phenolic acids, and low risk of mycotoxin contamination. Flax fibre resulted in best weight gains and feed conversion ratio (P ≤ 0.05) of piglets, while hemp fibre had higher positive effect on antioxidant status (P ≤ 0.05) compared to the other two fibre additives. Neither flax nor hemp fibres had any adverse effect on the haematological and biochemical blood parameters. Piglets receiving a diet with 1.5% added fibre showed better growth performance, while diet supplementation with 2% fibre had a beneficial effect on the content of butyric acid in the small intestinal chyme (P ≤ 0.05). The results suggested that both flax and hemp fibres can be innovative feed additives for weaned piglets. However, further studies should be conducted in commercial farms, as the effects of dietary fibre could vary in more challenging environmental conditions.

AMELIORATIVE EFFECT OF FERMENTED GOAT’S MILK COMBINED WITH DESERT TRUFFLE AND BAOBAB AQUEOUS EXTRACT IN CCL4 INDUCED LIVER LESION IN RATS

The aim of the present work was to investigate the synergistic hepatoprotective effect of fermented goat milk (FGM) combined with aqueous extracts of baobab (Adansonia digitata L.) (BE) and desert truffle (Terfezia claveryi) (DTE). Chemical analysis indicated that BE is rich in ascorbic acid (67.3 mg/100 g dry weight). Both extracts reduced the stable free radical DPPH (96.4 and for BE versus 70.2 % for BE and DTE, respectively). For examining the hepatoprotective effect of these treatments in vivo, thirty-six rats were randomly divided into six groups (n=6 per group). Group 1 served as the normal control (NC). Hepatotoxicity was induced in rats of the other five groups using CCl4. Group 2 served as the positive control (PC), while the remaining 4 groups received orally FGM, DTE, BE and their mixture (1:1:1) for 28 days. Hepatotoxicity was characterized by high liver weight as well as an elevation in serum levels of liver enzymes in the PC group. All treatments restored weight of liver to that of the NC group (P&gt;0.05). Highest positive effect was recorded for DTE which lowered liver weight by 33.9% compared with PC group (P&lt;0.05). Concentrations of liver enzymes were significantly reduced in all treatment groups compared to PC group. Moreover, the protective effect was further confirmed by histopathological as a considerable reduction in necrosis and fatty changes were noticed. In sum, FGM, Desert Truffle and Baobab could be potentially used as functional food to protect against liver lesion.

The Relation of Ideology of Positive Thinking with the Perception of Cancer Risk and Ways of Treating It in Medellin, Colombia.

This study has the following objectives: i) to construct an instrument to measure positive thinking ideology (PTI) regarding cancer, and to evaluate its psychometric properties, ii) to describe the effects of PTI on cancer risk and its treatment, and iii) to identify the associated factors with PTI in the study group. A cross-sectional study was conducted with 611 people from the Medellin, Colombia. Participants were selected through stratified sampling with proportional assignment. A survey with three constructs was applied: the role of negative emotions in cancer etiology, cancer as a redeeming event, and the effects of PTI in cancer treatment. In negative emotions construct 47% considered that holding anger, resentment, and hatred represent a moderate or high risk of generating cancer. In redeeming power construct 46.5% found that cancer is a battle that the best warriors win. Concerning the treatment, 77.3% considered that facing the disease with a fighting spirit had a moderate to high positive effect in response to the treatment. The associated factors with PTI were reading self-help books and education level. The results show that PTI affects perceptions about the cancer, its etiology and treatment. This effect is greater in undereducated people and in self-help book readers. The instrument showed excellent reliability, internal consistency, discriminating power, content, and construct validity properties.

Genetic Variability, Diversity, Heterosis and Combining Ability in Sponge Gourd [Luffa cylindrica (Roem.) L.

This experiment was conducted at Mandouri farm, Horticultural Research Station, Bidhan Chandra Krishi Viswavidyala (BCKV), West Bengal, India during March, 2014 to July, 2018. The objectives of the research were to determine genetic variability, phenotypic performance and diversity for yield and 17 yield attributing traits of the 45 sponge gourd germplasm. To study the heterosis and combining ability of parental lines with half diallel analysis for earliness and yield contributing characters. PCV (phenotypic coefficient of variation) was higher than GCV (genotypic coefficient of variation) for all the traits studied. Higher PCV and GCV were recorded for traits namely number of primary branches plant-1, number of fruiting nodes on main stem, sex ratio (male/female), fruits plant-1 and fruit yield plant-1. Based on Mahalanobis’ D2 statistic, the genotypes of sponge gourd were grouped into 7 different clusters. Fruit yield plant-1, weight of fruit and number of fruiting nodes on main stem had maximum contribution towards genetic divergence. Among the parents, Patna Local, IC-336759 and IC-284795 showed high significant positive GCA effects as well as per se performance for yield and yield related attributes. Additive as well as non-additive gene action regulating the different traits. The traits under non additive gene action. The magnitude of standard heterosis was found in desirable direction for early and yield traits viz., days to first pistillate flower appearance in the cross IC284795×Patna Loca (-23.07%), for 50% flowering in the cross IC-284795×Patna Local (-18.89%), sex ratio in the cross IC-336759×Patna Local (-53.41%), for number of fruit vine-1 in the cross IC-284795×Patna Local (34.56%) and average fruit weight in the cross IC336759×Patna Local (110.09%). Promising germplasm Patna Local may be subjected for regional yield trail along with released variety with a view to develop new variety of sponge gourd. The superior hybrids can be exploited for hybridization programme.
