Eggplant (Solanum melongena L.) is one of the most important fruit vegetables in the world, with several nutritional and medicinal benefits. However, little is known about the genetic divergence of yield and its related traits. The objective of this study was to explore gene action and heritability of traits to help direct and strengthen breeding programmes, geared towards improving yield of the crop. Six generations (P1, P2, F1, F2, BC1 and BC2) derived from two crosses (SM001-07 x ST004-03 and SM001 x San005-01) of eggplant accessions, were grown in pots in an open field, using Randomised Complete block Design (RCBD). Estimated data indicated that, the additive-dominance model was adequate to demonstrate the genetic variation and its significance in the inheritance of fruit weight, days to flowering and fruit yield traits. Although non-allelic interactions were found in plant height and number of seeds, additive effect was more pronounced in the genetic control of days to flowering and fruit weight; while dominance effect was more important in the control of plant branching and fruit length. Plant height and fruit yield were influenced by complementary gene action. Furthermore, the study revealed low magnitudes of dominance and environmental variances for most traits showing higher heritability values. In view of the diverse gene actions, with additive, dominant and epistasis, playing significant roles in the control of different traits, backcross, recurrent selection or bi parental could be appropriate for advancing the segregating populations to meet the need of yield improvement in both crosses. Key words: Additive, dominance, Epistasis, gene action

An experiment was carried out using eight double cross F1s (DCF1s) as lines and two testers to obtain sixteen Line ×Tester hybrids for the evaluation of major growth and flowering traits thereby to understand the breeding potentiality of the parental lines. The performance of growth and flowering traits of all twenty-six genotypes were evaluated in a randomized complete block design (RCBD) with three replications. The analysis of variance (ANOVA) showed all the genotypes were significantly different for all agro-morphological traits under study. The estimated general combining ability (GCA) effects showed that parent 5(P5), were superior for plant height, stem diameter, number of leaves, leaf length, days to flowering and attitude of floral axis followed by parent 2(P2) for leaf length, leaf width, days to flowering and attitude of floral axis and parent7 (P7) for number of flower, flower diameter, bud length and attitude for floral axis. Likewise; tester 1 found to be best combiner with significant GCA effect for almost all growth and flowering traits (except number of leaves). The plant height, leaf width, number of flower and attitude of floral axis showed prevailing additive gene action while stem diameter, number of leaves, leaf length, days to flowering, flower diameter and bud length indicated predominance of dominance gene action. We can conclude that parent P5, parent P2 and parent P7 can be used as good mother lines and the tester 1, as good donor for the seed production. SAARC J. Agri., 17(1): 175-187 (2019)

Forty two hybrids generated by crossing three testers with fourteen lines were studied along with parents for studying heterosis and gene action for days to first flowering, days to 50 percent flowering, fruit weight, fruit length, plant height, number of seeds per fruit, 100-seed weight and fruit yield per plant during rainy season and summer season of 2002-03 at Department of Horticulture, Indira Gandhi Agricultural University, Raipur, Chhattisgarh, India. The most heterotic combinations were VRO-6 x Parbhani Kranti, VRO-4 x Parbhani Kranti, Daftari-1 x Arka Abhaya and Kaveri Selection x Ankur Abhaya for fruit yield per ptant. The sca variances for days to fruit flower, days to 50 percent flowering, fruit weight, fruit length, plant height, number of seeds per fruit and 100-seed weight were higher than so gca variance so there is a preponderance of non-additive gene action. The gca variances was greater than sca variances for fruit yield per plant indicating preponderance of additive gene action for this trait. Overall, the results discussed above are quite indicative of the fact that hybrid okra has great potentialities of maximizing fruit yield in Chhattisgarh plains.DOI: http://dx.doi.org/10.3329/bjar.v32i3.544Bangladesh J.

The influence of different deficit irrigations on capsicum crop biometric parameters and fruit yield were assessed in an experiment the variety ‘Indra’ was tested using completely randomized block design with three deficit irrigations (0.50, 0.75 and 1.0 ETC) and 5 replications in polyhouse and 1.0 ETC in open field conditions. The biometric parameters namely plant height, number of leaves, number of branches, number of days to flowering; number of days to harvesting, number of fruits per plant, individual fruit weight and fruit yield are measured. From the results, observed that, average of plant height (91.23 cm), number of leaves (91.3), number of branches (6.9), number of days to flowering (32.7), number of days to harvest (71), fruit number per plant (7), individual fruit weight (75.99 g) and yield (6466.66 t ha-1) parameters found higher in 1.0 ETC (T1), but in case of water productivity (12.4 kg ha-1 mm-1) in the treatment (T2) 0.75 ETC showed superiority. From the results, it is determined that by adopting the 0.75 ETC (T2) we can save the water up to 25%. Aims: The objective of this study is to evaluate the influence of deficit irrigation in biometric parameters of capsicum. Study Design:  Completely randomized block design. Place and Duration of Study: Experiment conducted during January to May 2018 at Agriculture farm, College of Agricultural Engineering, Madakasira located in Rayalaseema region. Methodology: Physical and chemical properties of field were found by using standard methods. The experiment was arranged using CRD design with three levels of irrigation and five replications. Fertigation was done with 250:150:150 kg/ha recommended doses of N:P:K to capsicum crop. Based on climatological approach (evapotranspiration basis) the quantity of water applied. All the recommended cultural practices selection of cultivars, nursery raising, land preparation, laying drip lines, fumigation, fertilizer application, transplanting, pruning, training and plant protection measures are removing affected plant parts, flowers, fruits and for thrips and aphids management are dicofol (2 ml/L) and imidacloprid (0.5 ml/l) standardized for polyhouse were followed time to time to ensure a healthy crop stand. Crop water requirement was determined by using AquaCrop model. The parameters viz., plant height, number of leaves per plant and number of branches per plant were recorded at 30, 60, 90, 120 days after transplanting and at harvest. The collected data of different parameters during the course of research were analysed as per the completely randomized design (CRD) by applying the technique of analysis of variance procedure. Results: Among all the treatments, Irrigation with 100% Crop Evapotranspiration (1.0 ETc) (T1) registered the highest plant height, number of leaves, number of branches, number of days required to harvesting, number of days required to flowering, fruit number, average fruit weight and fruit yield, followed by 0.75 ETc (T2), 0.5 ETc (T3) and open field conditions. This might be due to good soil moisture distribution in drip irrigation compared to the open field. From the observed parameters it is exhibited that drip irrigation 0.75 ETC recorded as the higher water productivity (12.4 kg ha-1 mm-1) followed by drip irrigation scheduled at 1.0 ETC (11.49 kg ha-1 mm-1), 0.5 ETC (11.07 kg ha-1 mm-1) and open field (1.38 kg ha-1 mm-1) recorded very less. Conclusion: By adopting T2 (0.75 ETC) irrigation treatment we can save the water up to 25%, by using saved water additional quantity of vegetables can be produced.

The study was carried out to find out the effect of zinc (Zn) and boron (B) on growth and yield of okra (BARI Dherosh 1). The experiment was laid out in Randomized Complete Block Design (RCBD) with three replications. The treatments of the experiment were, T0 (without Zn or B), T1 (20 kg Zn ha-1), T2 (30 kg Zn ha-1), T3 (10 kg B ha-1), T4 (20 kg B ha-1), T5 (20 kg Zn ha-1 + 10 kg B ha-1), T6 (20 kg Zn ha-1 + 20 kg B ha-1), T7 (30 kg Zn ha-1 + 10 kg B ha-1) and T8 (30 kg Zn ha-1 + 20 kg B ha-1) were undertaken to evaluate the best results of the study. The highest plant height was found in T8 (30 kg Zn ha-1 + 20 kg B ha-1) but the highest number of leaves plant-1 was recorded from T7 (30 kg Zn ha-1 + 10 kg B ha-1). On the other hand, the maximum leaf area index, SPAD value, mean fruit weight, fruit length, fruit diameter, fruit dry matter (%), number of fruits plant-1, fresh fruit weight plant-1 , fruit yield plot-1 and fruit yield ha-1 were found in T7 (30 kg Zn ha-1 + 10 kg B ha-1), while the control (T0) showed lowest performance for the respected parameters. It is strongly concluded that 30 kg Zn ha-1 with 10 kg B ha-1 combination may be helpful for okra cultivation in the field level to increase okra production.
