Combining ability and gene action in cucumber (<em>Cucumis sativus</em> L.)

The experimental material for the present study comprised of F1 population of twenty four crosses, developed by crossing four female parents viz., Sheetal, Shubhangi, Himangi, and Puna khira of cucumber with six male parents viz., AAUC-2, DC-2, AAUC-1, VRC-19, DARL-103 and Fansu local. The experiment was laid out with 24 F1s, 4 females 6 males and one check Konkan kakadi in Randomized Block Design (RBD) with two replications during the kharif 2017.Observations were recorded on thirteen different quantitative characters The perusal of estimates of gca effects revealed that two female parents viz., sheetal (0.572), Puna khira (0.235) and two male parents Fansu local (0.596) and VRC-19 (0.376) exhibited significant positive gca effect in kharif 2017. This showed that these parents were good general combiner for the marketable yield vine-1. The best three hybrids with respect to marketable yield vine-1based on significant positive sca were viz., Sheetal x Fansu local (0.942), Shubhangi x DC-2 (0.532), Puna khira x VRC-19 (0.484). A perusal of the data indicated that the estimates of σ2SCA were higher in magnitude as compared to σ2 GCA (average) both in females and males for the traits under study viz., days to first male flower appearance, days to first female flower appearance, nodal position of first female flower, days to first picking, fruit length and diameter, average fruit weight, marketable yield vine-1, harvest duration and total soluble solids. In all the traits studied, the SCA variances were higher than GCA values, indicated the role of non-additive gene action.While lower magnitude of SCA showed additive gene action. The heritability estimates from different variance components having very high heritability obtained for number of marketable fruits vine-1 (69.02%) and number of primary branches plant-1 (94.40%).

Effect of phosphorus on growth and yield of sesame

The present study was conducted at the Research farm of Sher-e-Bangla Agricultural University, Sher-e-Bangla Nagar, Dhaka, during March to June 2014 to examine the effect of Phosphorus on the growth and yield of Sesame. BARI Til-3 variety was used for the study. This experiment was consisted of single factor eg. phosphorus. There were three levels of phosphorus viz. (i) P0 (0 % P), (ii) P1 (20 % P) and (iii) P2 (30 % P) and the experiment was laid out in a Randomized Complete Block Design (RCBD) with six replications. Different levels of phosphorus showed significant effect on growth and yield of sesame. Individually phosphorus had significant effect on highest plant height, number of leaves plant-1, number of primary branches plant-1, number of secondary branches plant-1, number of capsule plant-1, number of seeds capsule-1, 1000 seed weight, seed yield and harvest index. The highest plant height of sesame (136.30 cm), the highest no leaves plant-1 of sesame (34.44), number of primary branches plant-1 (5.56), number of secondary branches plant-1 (7.61), number of capsule plant-1 (25.87), number of seed capsule-1 (70.47),1000 seed weight (3.54), Seed yield (1581.00 kg ha-1), Stover yield (3034.42 kg ha-1), biological yield (4615.76), harvest index (34.11%), oil content (43.92%) was recorded from P1. Again, the highest days to first flowering of sesame (31.67) was recorded from P1 (20 % P) but the highest days to maturity was (85.67) recorded from P2 (30% P). Application of P at different percentage is causing effect in growth and yield of sesame.

Assessment of different tomato genotypes for yield and morphological attributes

Abstract This experiment was carried out to assess different tomato genotypes for yield and morphological attributes at Agricultural Research Station (ARS) Swabi during 2018. Experiment was laid out in a randomized complete block design (RCBD) with three replications. Results of the experiment showed significant differences among the tomato genotypes for all parameters except days to first flower initiation. Maximum number of flowers cluster-1 (20.0 flowers) were observed for tomato genotype 006231 and maximum number of fruits inflorescence-1 (15.0) were recorded for genotypes 006231 and 00289, respectively. Maximum number of primary branches plant-1 (10.0 branches) and secondary branches plant-1 (24.0 branches) were developed by tomato genotype 017875. Bombino produced maximum fruit length (5.84 cm) and fruit diameter (4.99 cm), respectively. Highest plant height was attained by genotype 017875 (102.5 cm) while Roma produced smaller plants (49.9 cm). Maximum numbers of fruit clusters plant-1 (28.0 clusters) were produced by genotype 00289 whereas Red Wonder showed maximum fruit yield plot-1 (3.74 kg). Higher values of phenotypic coefficient of variation (PCV) and genotypic coefficient of variation (GCV) were observed for number of secondary branches plant-1 (32.49% and 31.69%), number of fruit clusters plant-1 (29.03% and 25.94%), plant height (22.93% and 21.72%) and fruit yield plot-1 (42.92% and 39.63%). High broad sense heritability values were obtained for number of secondary branches plant-1 (95.1%), fruit diameter (66.8%), number of fruit clusters plant-1 (92.1%), plant height (89.7%) and fruit yield plot-1 (85.2%). On the basis of excellent performance for most of the yield and yield related parameters, the tomato genotypes Red Wonder, Bombino, 006231, 00289 and 017875 are recommended for onward use in tomato breeding programs for the development of commercial tomato varieties/hybrids.

Abstract A field study was conducted at Grdarasha Research Station of the College of Agriculture/ Salahaddin University– Erbil, during the growing season of 2017, to study the effect of sowing date on some growth parameters and yield of chickpea. A factorial experiment based on randomized complete block design (RCBD), with three replicates was used, sowing dates ( January 20, February 9, March 1, and March 21 ), and two cultivars of chickpea (Rafidain and Gab) were implemented. Sowing at January, 20 produced the highest plant height (43.0 cm), leaf area (797.83 cm2), leaf area index (2.66), dry matter (38.06 g m-2), crop growth rate (7.90 g m-2 day-1), number of primary branches plant-1 (3.55), number of pod plant-1 (21.60) and seed yield (2.160 t ha-1). On the contrary sowing at March, 21 recorded the lowest of all above studied characteristics, also Gab cultivar surpassed the Rafidain cultivar in all characteristics studied except no. of seeds plant-1 and 100-seed weight. From interaction sowing date with cultivars recorded the highest of all characteristics studied at sowing date January, 20 with Gab cultivars as well as Rafidain cultivar recorded the lowest of all studied characteristics at sowing date March, 21. There was positive highly significant correlation(r= 0.869) between seed yield and their components; no. of pods plant-1, no. of seeds pod-1 and 100- seed weight (r= 0.869, r= 0,810 and r= 0.706) respectively.

On-farm study was conducted in the lowland areas of Kewot district in the North Shewa Zone, Ethiopia on two sites during 2011 crop season to determine optimum seed rate of sesame. Four seed rates (2, 4, 6 and 8 kg ha-1) of sesame cultivar Adi, were arranged in a randomized complete block design (RCBD) with four replications at each experimental site. The results of analysis of variance showed that location and seed rate had no significant effect on grain yield and plant height. Similarly, interaction of seed rate and location had no significant effect on grain yield, plant height and number of branches plant-1. On the other hand, location and seed rate had significant (p≤0.05) effect in the number of branches plant-1. The maximum number of primary branches plant-1 (3.3) was obtained from the seed rate of 2 kg ha-1 and the minimum number of primary branches plant-1 (2.3) was obtained from the seed rate of 8 kg ha-1. Since the statistical analysis revealed non-significant difference among treatment yields, comparison was made by using total costs that vary. Accordingly, 2- 4 kg ha-1 seed rate found to be optimum for the production of sesame under rain-fed condition around Kewot district and similar areas. Key words: Adi, broadcast, Kewot, Medina, under rain-fed, Yelen crossing.

INTERRELATIONSHIPS AMONG YIELD AND YIELD CONTRIBUTING TRAITS IN CHICKPEA (Cicer arietinum L.)

Twenty chickpea genotypes including four varieties were evaluated for the existence of genetic variability and to know the interrelationship among yield traits under study during 2013-2014, at University of Agriculture, Faisalabad. The experiment was carried out in a randomized complete block (RCB) design with three replications. Data were recorded on number of days taken to flowering, number of primary branches plant-1, number of secondary branches plant -1, plant height, number of days taken to maturity, number of pods plant -1, numbers of seed pods-1, total plant weight, Number of grains plant-1, 100- seed weight and grain yield plant-1. The obtained data were analyzed for genetic variability parameters, correlation and path coefficient analysis. The height broad sense heritability estimates were obtained for 100-seed weight (0.977), plant height (0.971), total plant weight (0.971) and number of primary branches plant-1. Genetic advance was higher for plant height (9.054), total plant weight (9.054), number of pods plant-1 (6.414) and 100-seed weight (2.941). The phenotypic coefficient of variation (PCV) was invariably slightly higher than their corresponding genetic coefficient of variation (GCV) due to influence of environment on character expression. Heritability estimates were higher for all characters except number of days taken to maturity and number of grains per plant, which exhibited moderate heritability. Hundred seed weight, plant height, total plant weight and primary branches per plant would be the suitable selection criteria to accomplish better grain yield in chickpea.

Characterization of lentil (Lens culinaris M.) germplasm through phenotypic marker

An experiment was carried out to evaluate the performance of 22 lentil (Lens culinaris M.) genotypes for their yield and yield contributing characters at phenotypic level, relationship and diversity among the individuals and characterize the germplasm through phenotypic markers. ANOVA table revealed that significant variation was found among the genotypes for the characters plant height, days to maturity, number of primary branches plant-1, number of secondary branches plant-1, height of the lowest pod and 100-seed weight. Yield plant-1 was positively correlated with pods plant-1, seeds pod-1, seeds plant-1 and 100-seed weight. Considering yield plant-1 LM-123-7 was the best followed by LM-132-7, ICARDA-2348 and LM-13-1. Days to flowering, days of maturity and 100-seed weight showed high heritability. Path analysis revealed that pods plant-1 and 100-seed weight had positive direct effects on yield plant-1. The genotypes were grouped into five clusters based on Euclidean distance following Ward’s method and the highest intra-cluster distance was found in cluster IV and inter-cluster distance between the cluster IV and cluster V. Study of selection indices through discriminate functions observed that LM-123-7 ranked as the best followed by LM-132-7, LM-21-6, LM-24-3 and LM-14-2 and suggests that the highest scoring genotypes might be recommended for farmer’s cultivation for better yield.

An experiment was conducted at the Agronomy Field Laboratory, Bangladesh Agricultural University, Mymensingh from December 2009 to March 2011 to determine the effect of date of planting on growth and leaf yield of Stevia. The experiment comprised 24 dates of planting in the year of 2010 viz. 1 January (T1), 15 January (T2), 1 February (T3), 15 February (T4), 1 March (T5), 15 March (T6), 1 April (T7), 15 April (T8), 1 May (T9), 15 May (T10), 1 June (T11), 15 June (T12), 1 July (T13), 15 July (T14), 1 August (T15), 15 August (T16), 1 September (T17), 15 September (T18), 1 October (T19), 15 October (T20), 1 November (T21), 15 November (T22), 1 December (T23) and 15 December (T24). The experiment was laid out in a Complete Randomized Design with three replications. Twenty four dates of planting were included in the experiment in 72 earthen pots (24 X 3) of 30 cm diameter X 30 cm height. Stem cuttings were placed in shaded seed bed for root initiation. Twenty one - day old stem cuttings were used as planting material. Stem cuttings were transplanted in the pots on the specific dates. Different dates of planting had significant effect on the growth and yield parameters. 1 April 2010 (T7) planting proved to be the superior to the other treatments i.e. plant height (68.50cm), number of leaves plant-1 (142.33), number of primary branches plant-1 (37.33), fresh weight of leaves plant-1 (14.11g), fresh weight of primary and secondary branches plant-1 (11.06g and 20.91g), dry weight of leaves plant-1 (3.38g) which might be due to warm environmental conditions like clear sunshine and high temperature. The overall results suggested that stevia seedlings may be planted from 15 February to 30 April for better yield of leaves. DOI: http://dx.doi.org/10.3329/jbau.v10i2.14684 J. Bangladesh Agril.

Growth, herb yield and phytochemical contents in a medicinal herb Andrographis paniculata under saline irrigation.

Andrographis paniculata (King of bitters/Hempedu Bumi) is a traditional medicinal herb of family Acanthaceae. It is commonly used to cure a variety of ailments and diseases. This study was designed to evaluate the herb yield and phytochemical contents in two germplasm accessions of Malaysian A. paniculata, viz. 11261 and 11265, grown with different quality of irrigation water, that fresh (EC iw 0.12 dS m -1) and saline (EC iw 2.5 and 5.0 dS m -1). Just before blooming, the plants were harvested to record data on six basic traits, including plant height, length and width of main-stem leaves, length and number of primary branches plant-1 and dry herbage yield (plant-1). Concentrations of Na + and K +, coupled with K +/Na + ratio, were determined in the cell sap extracted from the top fully matured leaves. Phytochemicals, viz. Andrographolide (AG), Neoandrographolide (NAG) and 14-deoxy-11, 12- didehydroandrographolide (DDAG), were determined in the dry matter of aerial parts using highperformance liquid chromatography (HPLC). No significant changes in plant growth and dry herbage yield (plant-1) were observed with 2.5 EC iw (dS m -1) water, compared to 5.0 EC iw water, where reductions in same indices were >13% and statistically significant. Adverse effects of water salinity on growth and dry herbage yield can be attributed with significantly higher concentration of Na + and lower concentration of K + and lower K +/Na + ratio in the leaf sap. Phytochemical contents in dry matter were generally unaffected by water salinity. With the exception of Na + concentration in leaf sap, response of both accessions to saline irrigation was similar. These results suggest that both accessions exhibited good potential to withstand to salty water environment and produce considerably high amount of phytochemicals under both normal as well as saline irrigation conditions.
