Frequency of heterotic hybrids in relation to general combining ability of parents in sweet corn.

The success of developing prominent hybrids directly depends on the selection of parents with good combining ability which can transfer desirable genes with additive effects to their progeny. The data of 42 hybrids generated using 7×7 full diallel design; their seven parents along with three check hybrids were subjected to combining ability analysis from the experiment that was carried out during rainy season 2019. The analysis of variance showed significant general combining ability, and specific combining ability mean sum of squares for all the thirteen characters studied. It is obvious from the results that three lines (SC Sel 2, SC Sel 1 and SC Sel 3) showed high overall general combining ability status, suggesting these lines as good general combiners across traits. Eighteen hybrids had high overall specific combining ability status, while nearly 52% (22 hybrids), 57% (24 hybrids) and 47% (20 hybrids) of crosses showed high overall mid-parent, better-parent and standard heterosis. The unique superiority of crosses involving high overall general combiner parent in the crosses highlighted the importance of using such parents to realize high heterotic crosses. A non-linear relationship between high overall specific combining ability status and heterotic status of hybrids was noticed. The probability of obtaining a cross with high standard heterosis was more with employing parents with high general combining ability status.

Genetic variability and association studies in Sunflower Inbreds

Genetic variability, heritability, genetic advance and association studies were carried out in 87 sunflower inbreds shared by different AICRP centres for six yield and its contributing traits. Results of ANOVA showed highly significant mean sum of squares for all the traits indicating presence of sufficient variability in the experimental material. Wide range of variation was noticed in plant height followed by seed yield and days to 50 % flowering. High phenotypic and genotypic coefficient of variation were recorded for head diameter, seed yield per plant and 100 seed weight. High heritability coupled with high genetic advance as per cent of mean was exhibited for seed yield indicated directional selection could be effective. Head diameter recorded strong correlation with seed yield followed by plant height and 100 seed weight and in turn these traits were also strongly intercorrelated.

Integrated artificial and deep neural networks with time series to predict the ratio of the low bid to owner estimate

PurposeThe variance between the winning bid and the owner's estimated cost (OEC) is one of the construction management risks in the pre-tendering phase. The study aims to enhance the quality of the owner's estimation for predicting precisely the contract cost at the pre-tendering phase and avoiding future issues that arise through the construction phase.Design/methodology/approachThis paper integrated artificial neural networks (ANN), deep neural networks (DNN) and time series (TS) techniques to estimate the ratio of a low bid to the OEC (R) for different size contracts and three types of contracts (building, electric and mechanic) accurately based on 94 contracts from King Saud University. The ANN and DNN models were evaluated using mean absolute percentage error (MAPE), mean sum square error (MSSE) and root mean sums square error (RMSSE).FindingsThe main finding is that the ANN provides high accuracy with MAPE, MSSE and RMSSE a 2.94%, 0.0015 and 0.039, respectively. The DNN's precision was high, with an RMSSE of 0.15 on average.Practical implicationsThe owner and consultant are expected to use the study's findings to create more accuracy of the owner's estimate and decrease the difference between the owner's estimate and the lowest submitted offer for better decision-making.Originality/valueThis study fills the knowledge gap by developing an ANN model to handle missing TS data and forecasting the difference between a low bid and an OEC at the pre-tendering phase.

GENETIC PARAMETERS AND PRINCIPAL COMPONENT ANALYSIS FOR QUANTITATIVE TRAITS IN RICE (ORYZA SATIVA L.)

Conventional breeding is vital in improving yield-related traits and developing high-yielding cultivars. In the presented study, an evaluation of 15 F1 hybrids compared them to their six parental genotypes for genetic variation of various traits. The results showed that the analysis of variance revealed significant (P ≤ 0.01) differences among the cross combinations and parental cultivars and among the parents and crosses. The mean sum of squares of parents vs. crosses also indicated substantial (P ≤ 0.01) for all the characteristics. The general (GCA) and specific combining ability (SCA) variances were significant (P ≤ 0.01) for all traits studied in the F1 generation. Three varieties, namely, Sakha108, Giza179, and Sakha109, were highly significantly positive for grain yield plant-1, which means these varieties can benefit as good combiners to transfer the said trait in the breeding program. In SCA, seven crosses were negative in plant height and a negative value was desirable to avoid lodging and suitable for mechanical harvesting; however, positive significant values are preferable in the rest of the traits. The results indicated that the best crosses for grain yield plant-1 and plant height were Sakha105 × Sakha102, Sakha105 × Sakha108, and Sakha108 × Sakha109. Conducting cluster analysis also exhibited the genotypes dividing into four groups. The first group included rice genotypes Sakha109 and Sakha108 alone. These cultivars, produced from a common parent Sakha101, could have genetic relations for three quantitative traits (flag leaf area, 1000-grain weight, and panicle weight). The second group, comprising Sakha 102 and Sakha 106, has a very similar genetic background because both cultivars share a common parent, Giza 177. In addition, these two rice cultivars had at par number of tillers plant-1, 1000-grain weight, and panicles plant-1. The third group included only Giza 179 belonging to Indica-Japonica varieties. A fourth group has Sakha 105 produced by different parents.

Variations in Phenotypic Characteristics of Vigna Unguiculata (L) Walp. Seeds Sourced From Open Markets in Benin City, Nigeria

Vigna unguiculata, ‘cowpea,’ is a crop of numerous varieties. In Benin City, Nigeria, the three common varieties are “Ife Brown”, “Ekpoma Local”, and “Sokoto White”. Being a very common delicacy and perhaps a cheap source of protein for the population, it is sold in nearly all available open markets. The crop is mainly consigned from numerous farms in the north and thus, is very amenable to genetic diversity. This study was undertaken to investigate the differences within and between these varieties. The seeds obtained from major open markets in Benin City were morphologically characterised quantitatively and qualitatively using standard descriptors. Seed length, width, thickness, weight, and volume were the quantitative parameters, while the qualitative parameters included seed brilliance, shape, eye colour, eye pattern, splitting of testa, testa texture, basal colour, pattern of variegation, colour of variegation, and basal colour of variegated seeds. Only “Ife Brown” varied in qualitative parameters, particularly the seed colour. Among the seed quantitative parameters measured, seed volume was the most diverse, with “Sokoto White” being significantly diverse compared to the others. “Ife Brown” was the most varied species among the three in the markets of Benin City, with a group mean sum of squares of 146.95.

Elucidation of Combining Ability and Gene in Bottle Gourd [Lagenaria siceraria (Mol.) Standl.

Aims: To Study combining ability effects and evaluate gene action for fruit yield with associated traits of bottle gourd.
 Study Design: Randomized block design.
 Place and Duration of Study: The seeds of F1 hybrids were produced during summer 2021 at Potato Research Station, S. D. Agricultural University, Deesa.
 Methodology: The experimental material consisted of twelve parents, their 35 Line × Tester crosses and one standard check (ABGH 1).
 Results: The analysis of variance for combining ability revealed that the mean sum of squares due to female (lines) and male (testers) were highly significant for all the traits except fruit girth, average fruit weight, chlorophyll a, chlorophyll b and total chlorophyll. The gca effects indicated that four male parents ABGS 14-25, ABGS 11-17, ABGS 11-24 and PUNJAB LONG and three female parents DBG 5, NDBG 132 and LOCAL were found good general combiners for fruit yield per plant and its some of the contributing traits. Based on estimates of sca effects, the most promising hybrids for fruit yield per plant were DBG 5 × ABGS 14-27, NDBG 132 × PUNJAB LONG and GPBG 108 × ABGS 11-24. The good general combiners for fruit yield and contributing traits can be utilized in intensive crossing programme and select transgressive segregants for desired characters in segregating generations to develop superior lines.
 Conclusion: The ratio of σ2GCA / σ2SCAwas less than unity for all the characters under study, which suggested greater role of non-additive genetic variance in the inheritance of these characters. The genetic components of variance revealed that different type of gene action were involved for fruit yield associated with different traits in bottle gourd.

Genetic diversity analysis for seed yield and quality characters in sesame (Sesamum indicum L.)

Genetic divergence wasstudied by growing thirty six genotypes ofsesame, Sesamum indicum L. at Agricultural Research Station, Mandor, Jodhpur during rainy season 2010. The mean sum of squares were significant for all the characters, indicating the presence of variability. Characters like seed yield, free fatty acid, oxalic acid content, number of productive capsules/plant and productive branches/plant exhibited high heritability coupled with high genetic advance revealing that these characters were controlled by additive gene action. The hierarchical cluster analysis indicated the presence of considerable genetic divergence among the genotypes. The genotypes were grouped into seven clusters using Ward's minimum variance method. The intercluster Euclidean2 distance was maximum between cluster III and VII (42.71) followed by cluster VI and VII (41.90) and cluster II and VII (39.03) which indicated that the genotypes included in these clusters will give high heterotic response and thus bettersegregants. The maximum cluster means were revealed by cluster III for days to 50% flowering, maturity, number of productive branches/plant, oxalic acid content and free fatty acid followed by cluster VI for seed yield, number of productive capsules/plant and oil content, and clusterI and IV for plant height and 1000 seed weight,respectively. While cluster VII showed minimum cluster mean for days to maturity, plant height and free fatty acid and cluster I and IV for oxalic acid and days to 50% flowering. Among the 10 characters, number of primary branches/plant contributed the most (12.06%) towards the divergence of genotypes.

Genetic Variability in Vegetable Pea (Pisum sativum var. hortense) Genotypes in Bundelkhand Region

This study aimed to assess the genetic variability in vegetable pea (Pisum sativum var. hortense L.) under the Bundelkhand region. A total of 25 pea accessions were collected from different regions of Uttar Pradesh and Bundelkhand and evaluated for various traits. The estimates of the mean sum of squares due to genotypes were highly significant for all the characters showing the existence of genetic variation in the source material. For the majority of the quantitative characteristics and qualitative traits, high phenotypic and genotypic coefficients of variation were observed. Most of the traits showed high heritability together with high genetic advance. Based on the mean performance the genotypes/variety Narendra Matar 2, VVP 1, JVP 1 and JVP 2 had the highest yield. The variety VVP 1 has good plant height, high seed and pod weight. The varieties JVP 1 and Kashi Nandini have taken fewer days to maturity and also yielded well so these varieties can be also recommended for use a parent for improvement of local material in the Bundelkhand region.

Genetic Diversity Analysis for Yield and Yield Attributing Traits in Finger Millet (Eleusine coracana L.)

The present investigation was carried out to assess the genetic variability, heritability, genetic advance, genetic diversity in 37 finger millet genotypes for 15 quantitative traits during Kharif, 2022 at Field Experimentation Centre, Department of Genetics and Plant Breeding, Naini Agricultural Institute, Sam Higginbottom University of Agricxulture Technology and Sciences, Uttar Pradesh in Randomized Block Design with 3 replications. The analysis of variance for mean sum of squares due to genotypes showed significant differences for all the 15 quantitative characters. The genotype, IE-184 followed by IE-195, IE-185, IE-191, IE-199, IE-180 exhibited highest grain Yield per Plant, while IE-111, IE-150, IE-169, IE-170, IE-175, IE-168 genotypes are early in maturity. Whereas, genotypic and phenotypic coefficient of variation were found high for flag leaf length, number of productive tillers, number of fingers per ear, finger length. High heritability and high Genetic advance were recorded in plant height, flag leaf length, ear width, number of fingers per ear, finger width. Clustering by Tocher’s Method has grouped all 37 genotypes into 6 clusters, in which Cluster-I contains more (16) genotypes and Cluster-IV, Cluster-V, Cluster-VI contains less (1) genotypes. According to Mahalanobis Euclidean Distance (not to scale), the maximum Inter-Cluster distance is recorded between Cluster-I and Cluster-VI (10.52) followed by Cluster-II and Cluster-V (10.44), Cluster-II & Cluster-III (9.35), Cluster-II & Cluster-IV (9.21). Plant height followed by grain yield per plant and days to 50% flowering traits contributes the highest percentage towards the overall divergence among the genotypes. Hence the selection of genotypes based on the above-mentioned characters and Inter Cluster Distance will be useful for crop improvement in Finger Millet.

Theoretical Study for Adjusting ANOVA Procedures For The One-Way Random Effects Model Under Correlated Errors Within Class And Across Classes

In this study, a method was developed to adjust the procedures of analysis of variance for the one-way balanced random effects model when error limits across classes are not independent, while the assumption of independence between the error terms among the different classes is essential in the analysis of variance. The variance-covariance structure and the correlation coefficients for the error limits were defined. The was assumed as the correlation coefficient of error terms within the class and the is the correlation coefficient for error terms in different classes. The work performed by deriving correction factor and calculating the expectation of the mean sum of squares of errors and treatments as well as correcting the f-statistic.

Performance Evaluation of Brinjal (Solanum melongena L.) under Mid Hill Conditions of Uttarakhand, India

Brinjal (Solanum melongena L.), belongs to the family Solanaceae, which is an important vegetable crop of sub-tropics and tropics. The present investigation was carried out at the Vegetable Research and Demonstration Block, College of Horticulture, VCSG UUHF, Bharsar, during Kharif, 2017 to evaluate diverse germplasm of brinjal under mid hill conditions. The experiment was laid out in RCBD with three replications. In this study, twenty-seven genotypes viz., DRNKV-02-104, IVBL-116-131, NBJ-19, JB-9, Aruna, JB-2, CH-1045, Swarna Shree, JB, DRNKV-104-43, RCMBL-04-04, IBH-2, Kavya, B. Dewariya, DBR-8, DMU-1, Azad Brinjal-2, Co-11, JB-67, KKM-1, BCB-464, PLR-1, JB-18, Bhagyamati, BB-58, Pusa Shyamala including one check cultivar Pant Samrat were evaluated for different horticultural traits. During the investigation, 18 growth, flowering, fruiting, yield and quality parameters were recorded. The result of variance revealed that the mean sum of square due to treatment were significant at 5% level for all the traits. The genotypes, Aruna, DRNKV-02-104, NBJ-19, JB-2, RCMBL-04-04, IVBL-116-131 and Kavya recorded higher fruit yield and also performed better for other horticultural traits than check cultivar. These genotypes need to undergo additional testing before being made available as a replacement for currently available brinjal varieties, or they can be included in additional breeding programmes to develop improved varieties or hybrids of brinjal.

Performance and Genetic Evaluation of Okra (Abelmoschus esculentus (L.) Moench) Genotypes for Agromorphological Traits

Okra or Bhendi is a crucial vegetable farmed in India. The state of Tamil Nadu contains a smaller cultivable area and less okra production. As a result, the investigative study was conducted at Sivapuri, Chidambaram, Tamil Nadu to estimate variability metrics such as PCV, GCV, and GA% mean for crop advancement studies. The experiment involved 48 okra genotypes and 12 qualitative variables. In accordance with ANOVA, the mean sum of squares of 48 genotypes was highly significant for all parameters tested. For the twelve studied traits, values of PCV was higher than values of GCV by a little margin, showing the influence of environmental influences on genotypes. High heritability was found in all characters except days to 50% flowering and days to first harvest. High genetic advance % of mean was perceived in all the traits except for days to the 50% flowering, the harvest period and days to first harvest. High heritability combined with high GA was recorded in traits like primary branches per plant, fruit girth, no. of fruits per plant, fruit length, and fruit yield per plant. If genotypes are chosen based on these traits, selection for genetic improvement programs would be highly efficient.

Estimation of Combining Ability, Gene Action and Components of Genetic Variation in Forage Sorghum [Sorghum bicolor (L.)

Aims: To Study the combining ability effects and evaluate the genetics of the parents for fodder yield and its component traits in sorghum.
 Study Design: Randomized block design.
 Place and Duration of Study: The seeds of F1 hybrids were produced during summer 2022 at Center for Millets Research, S. D. Agricultural University, Deesa.
 Methodology: Six parental genotypes were used in the experiment, which produced 15 half-diallel crosses in sorghum.
 Results: The analysis of variance for combining-ability (CA) studies revealed that mean sum of squares due to general combining ability (GCA) were important for most of the characters except the leaf length of blade. Based on the gca effect, the parents CSV 46, IS 3338 and Malwan were good general combiners for green and dry fodder yield per plant. The unit slope of regression line and non- significant t2 value asserted the validity of the additive-dominance model for total plant height, number of leaf per plant, stem diameter, leaf length of blade, leaf width of blade, dry fodder yield per plant and crude protein content in dry fodder. The value of H1 was superior to H2 for most of the characters representing that gene distribution frequency in the parent genotypes was asymmetry and that was supported by the ratio of H2/4H1 (i.e., less than 0.25). The KD/KR components value was greater than one among most of the traits except for number of leaf per plant and crude protein content in dry fodder showed that parents had more dominant genes compared to recessive genes frequency.
 Conclusion: The ratio of σ2gca/σ2sca being more than unity, which suggested greater role of additive genetic variance in the inheritance of these traits. The genetic components of variance and graphical analysis revealed that different type of gene action were involved for forage yield and components traits in sorghum.

Effect of Different Organic Manures and their Combina- tions on Growth, Yield and Quality of Bitter Gourd cv Pusa Do Mausami under Sub Tropical Condition of Garhwal Hills

Present research work on the effect of different organic manures and their combinations on growth, yield, and quality of bitter gourd cv Pusa Do Mausami were carried out at the Horticultural Research Center, Department of Horticulture, HNB Garhwal University, Uttarakhand during the summer season of 2017. The experiment was comprised of 11 treatments consisting of different organic manures and their combinations which were laid out in Randomized Block Design with three replications. The result of the analysis of variance revealed that the mean sum of squares due to treatment was significant at a 5% level for almost all the traits. The result showed that T9 (vermicompost + poultry manure) responded best for days taken to the appearance of the first male flower (55.53) and female flower (61.53), number of fruits/vine (28.06), weight of fruit (71.67g), days taken to first fruit harvest (80.53 days) and harvesting duration (60.40 days). The treatment T4 (neem cake) showed best for diameter of fruit (44.4 mm), fruit yield/vine (1793.06 g), yield/plot (16.13 kg/plot) and yield/hectare (179.25 q/ha), respectively. On the other hand, the highest TSS (5.28 oBrix) and ascorbic acid (89.99 mg/100 g) content was estimated in T3 (goat manure). Thus, it can be concluded that the treatment T4 (neem cake) and T3 (goat manure) showed superior results with respect to yield and quality traits of bitter gourd respectively. Hence, these treatments could be used to enhance the production of bitter gourd under subtropical condition of Garhwal hills.

Heterosis and combining ability studies under artificial epiphytotic condition for yield and its related traits in Indian mustard

The performance of Indian mustard genotypes for eleven morpho-physiological traits was assessed. Genotypes (lines) having white rust resistance viz., BioYSR, Donskaja, Heera and Basanti, were crossed with genotypes (testers) having high per se performance for yield viz., Varuna, Kranti, RH749 and Giriraj in the line × tester fashion. The analysis of variance revealed significant mean sum of squares due to crosses for all traits. All traits, except area under disease progression curve and daysto 50% flowering, showed both, additive and a predominance of non-additive gene action. Results suggested that heterosis breeding would lead to good result. All traits had lower levels of narrow sense heritability, as well. Predominance of non-additive gene action coupled with low heritability suggested that, selection should be practised once plant reach sufficient levels of homozygosity. Single seed descent method with large F2 and diallel selective mating design would be preferable for obtaining superior pure lines. Additionally, all lines showed significant desirable general combining ability for disease resistance. Varuna × BioYSR was the only cross that showed significant heterosis for yield over national check, Kranti. It also revealed significant heterobeltiosis for: seeds per siliqua, number of primary branches, days to 50% flowering, AUDPC and days to maturity. This potential hybrid can be deployed with the help of cytoplasmic-genetic male sterility, or it can be utilised to obtain superior purelines through conventional breeding methods.

Combining ability analysis of newly developed male lines of castor (Ricinus communis L.) in Rajasthan

Genetic parameters of 50 castor hybrids developed using 10 newly developed male inbred lines and 5 stable pistillate lines were estimated in a line x tester design. Analysis of combining ability depicted significant mean sum of squares for both general combining ability (GCA) and specific combining ability (SCA) for all the characters which indicated the presence of both additive and non-additive gene actions. The high amount of s 2 SCA and ratioof GCAto SCA variances near to zero indicated that the dominance gene effect was predominant in newly developed lines for all the characters under study. The highest positive gca effect was exhibited by MCP-1-1, for seed yield and number of capsules on primary raceme, effective length of primary raceme and height up to primary raceme. SKP-84 was also good general combiner for traits such as 100-seed weight, number of capsule on primary raceme, nodes to primary raceme and height up to primary raceme. Among the male parents, MP-11-17 was found the best general combiner for cumulative seed yield, raceme length and number of capsule. Cross M-574 x MP-17-17 was identified as the best cross for cumulative seed yield followed by MCP-3 x MP-7-17 and SKP-84 x MP-11-17. These combinations of crosses would be useful in breeding programme for improvement in cumulative seed yield of castor.

Genetic variability, heritability, association and divergence studies in safflower (Carthamus tinctorius L.) genotypes

Genetic variability, heritability, genetic advance, divergence, association and path analysisstudieswere carried out in 13 safflower genotypes for nine yield and its contributing traits. Results of ANOVA showed highly significant mean sum of squares for all the traits indicating presence of high variability in the experimental material. Wide range of variation was noticed in seed yield followed by plant height, number of capitula/plant and number of seeds/capitulum. High phenotypic and genotypic coefficient of variation were recorded for number of seeds/capsule, 100 seed weight and seed yield. Low heritability coupled with high genetic advance as percent of mean was exhibited for seed yield indicated that yield is governed by additive gene effects and is highly influenced by environment. Hull content recorded strong correlation with seed yield followed by volume weight and 100 seedweight and in turn these traits were also strongly inter-correlated. Volume weight had high direct effect on seed yield and its indirect effect via hull content and 100 seed weight was also of high magnitude. In the experimental material, genetic divergence was mainly contributed by oil content, days to 50% flowering and number of seeds/capitulum.

Insight the Quality Parameters of Diverse Rice Germplasm Set of Chhattisgarh

The present study focuses on the evaluation of quality parameters of 198 rice genotypes including standard checks in augmented RCBD design. In ANOVA treatment ignoring blocks, heterogeneity among block was eliminated and for every new added treatment the mean sum of square for all the traits were found to be significant at 1% level of significance. Traits viz., milling recovery, iron content and degree of milling were skewed, while rest were normally distributed. Trait paddy and grain length were found to be highest for accession Dokra dori (12.44mm),Milling recovery was noted high for Luchai mutant (72.66%). Degree of milling found highest for Jeeraphool (93.95%). Apparent amylose content was highest in Ambemohar mutant-1(33.2%). Principal component analysis revealed that PC1 and PC2 explains variation for the trait, length and width of paddy, brown rice and milled rice transgressive segregants can be obtained for these traits by crossing genotype Chiko and Chaptigurmatiya parent, Angur gucha and Gobi buta, Chiko and Visnubhog mutant V-80, Khatia pati and Shri kamal as these were depicted as most diverse genotype.

Genetic Parameters and Diversity Studies Among Morphological Traits in Breeding Lines of Garlic (Allium Sativum L.)

Thirty-four promising lines of garlic were grown in randomized block design with three replications under the latesown season in 2019-20 at Vegetable Research Farm of C. S. Azad University of Agriculture and Technology, Kalyanpur, Kanpur. The mean sum of squares showed highly significant differences among the lines for all the traits studied, indicating the presence of a sufficient amount of genetic variability. The moderate to higher magnitude of the coefficient of variation at genotypic as well as phenotypic levels was noticed for number of cloves per bulb, marketable bulb yield, average weight of bulb, average weight of cloves and plant height. High heritability coupled with high genetic advance as percent of mean was observed for plant height, leaf length, leaf width, polar diameter, number of cloves per bulb, average weight of bulb and average weight of cloves. Marketable bulb yield was positively and significantly correlated with the total bulb yield and dry matter content whereas, a significant negative correlation with leaf width. All the thirtyfour lines of garlic were grouped into five clusters based on Mahalanobis D2 statistics using Tocher’s method. The cluster II and V had among the moderate genetic distance having higher total bulb yield performance along with its contributing traits. The genotypes from cluster IV and V had the most divergent clusters and were suitable for high yielding garlic genotypes among the various advanced breeding lines under late sown conditions.

Phenotypic Stability Analysis in Brinjal Over Environments

The study was conducted during rabi-2021 (Jan, 2021–Feb, 2021) and late kharif (Sept, 2021–Feb, 2022) at JAU, Junagadh, Gujarat to study the G×E interaction and stable genotype over environments (Seven parents (GJB-2, GJB-3, GRB-5, JBCL-10-12, JBCL-16-12, JBCL-17-01 and Swarna Mani Black SB) were intermated in full diallel fashion to obtain 42 hybrids (including reciprocals) , and evaluated in three environments viz., normal fertilizer (E1, 100:50:50 NPK, kg ha-1), at Vegetable research station, organic condition (E2, well rotten FYM+Vermicompost) and 25% high fertilizer dose (E3, 125: 62.5: 62.5 NPK, kg ha-1) at Instruction farm of Agronomy, JAU, Junagadh, Gujarat, India in Randomized Block Design (RBD) with three replications . The mean sum of squares due to genotype (G), environment (E), G×E interaction and E+(G×E) obtained significant for all the traits indicating that characters significantly interacted in different environments and environment created by different dose of fertilizer was justified. The environment index indicated that normal fertilizer environment was best suited for most of traits and organic environment suited for TSS content. Phenotypic stability analysis revealed that stable genotypes GRB-5 and GJB-2×GRB-5 and GRB-5×SB for days to first flowering, GJBH-4, GJB-2×SB, GJB-3×GJB-2 and SB×GJB-2 for days to first picking, SB×JBCL-16-12 for fruit girth, JBCL-17-01× GJB-2 for number of fruits plant-1 and GJB-3, GRB-5 and GJB-3×SB for TSS content over environments. GRB-5×JBCL-16-12 suitable for better environment for fruit yield plant-1. None of the parent and cross found stable for fruit yield plant-1 over environments suggested that environment difference was wider and genotypes stable for other traits can be used in future breeding programme for developing stable genotypes.
