Seed priming has potential to improve seedling development and plant growth under environmental stress. In this study, seeds of soybean cultivar LS678 and TGx1835-10E were pretreated with an optimum level of benzyladenine (4.87 mgL-1) before sowing into pots containing pasteurised mixture of vermiculite and sand. Plants were grown up to V3 stage before exposure to moderate and severe drought stress. According to the results, germination was rapid in hydroprimed seeds than BA primed seeds, which took longer to emerge. However, growth, yield and biomass of BA primed plants were increased (number of branches per plant- 7.32, flowering-87.6%, 100 seed weight- 22.6 g, overall biomass fraction- >40.5%) compared to plants developed from hydroprimed seeds (number of branches- 3.61, seed weight- 19.2 g, biomass- 12%) under similar growth conditions. This study indicated that, hormonal seed priming with BA reasonably enhanced soybean growth, particularly root biomass, flowering and fruiting. These effects further suggest that BA may play a significant role in improving drought tolerance in soybean.

Soybean MAGIC lines are highly variable breeding material which utilizes both recent and historic genetic recombination events. Present investigation was carried out to assess the genetic diversity present among 95 soybean MAGIC lines along with six checks for 10 different quantitative traits. All the genotypes were grouped into 16 clusters by performing Tocher’s clustering method using Mahalanobis D2 distance. Cluster I was the largest comprising of 30 genotypes followed by cluster II (23 genotypes), cluster X (15 genotypes) and cluster IX (9 genotypes). The maximum genetic distance (D2) was observed between cluster XI and XV (168.37) followed by cluster III and XV (164.3), cluster X and XV (149.64) as well as between cluster XII and cluster XVI (145.99). The cluster mean for most of the traits were high in cluster I and cluster XVI. Oil content contributed maximum (23.86%) towards total genetic diversity followed by number of pods plant-1 (18.97%), seed yield plant-1 (18.63%), 100 seed weight (11.05%) and number of branches plant-1 (10.16%) traits. The soybean MAGIC lines belong to the cluster XI (6-120) and cluster XV (6-30, 6-31, 6-5) were found to be the most divergent hence can be utilised in the recombination breeding programs to exploit maximum heterosis.

An experiment was carried out at the research farm of Patuakhali Science and Technology University (PSTU) during the period from November 2010 to April 2011 to study on growth and yield performance of cowpea (BARI Falon-1 and local Falon) with different concentration of GA3 (control, 25.00, 33.33, 50.00 and 100.00 ppm) to find out the suitable variety and optimum level of  gibberelic acid (GA3) application which would be also suitable to cultivate under coastal region of Patuakhali. Among the treatments, GA3 at 33.33 ppm treated plant of BARI Falon–1 showed the better performance on growth and yield contributing characters. As a result, the tallest plant (62.53 cm), number of leaves and branches plant–1 (28.67 and 20.07, respectively), TDM (83.99 g), CGR (1.68 cm2 day-1), RGR (0.729 cm2 day-1) and NAR (1.275 cm2 day-1) were exhibited from the variety BARI Falon-1 with the spraying of GA3 at 33.33 ppm at harvest. Yield contributing characters had also higher such as pods plant–1 (11.67), length of pod (17.20 cm), seeds pod–1 (16.80), 100-seed weight (12.49 g), seed yield (20.16 g plant-1 and 3139.93 kg ha-1) and harvest index (24.04%) with the variety BARI Falon–1 whily it was treated by 33.33 ppm GA3. Hence, it can be concluded that the application of GA3 up to 33.33 ppm than other GA3 levels and BARI Falon-1 than Local Falon would be the most suitable for obtaining the greater yield of cowpea under the coastal area of Patuakhali region. So, considering the above observation, BARI Falon-1 therefore is suggested to cultivate in Patuakhali region while 33.33 ppm GA3 would be also optimum level for the better prodcution of cowpea.Progressive Agriculture 27 (2): 94-100, 2016

<p>Genetic parameters are important in genetic improvement and variety development. This study aimed to determine the effective characters that can be applied as selection criterion in soybean breeding using genetic parameters. About 100 soybean genotypes were grown in the Muneng Agricultural Technology Research and Assessment Installation from April to July 2020. The trial was conducted using a randomized complete block design. The results showed that high genetic variability was found on days to maturity, number of branches per plant, number of productive nodes per plant, 100-seed weight, and seed yield. The high heritability was shown by days to maturity, plant height, number of branches per plant, and 100-seed weight. All phenotypic correlations were significant, except for the correlation between seed yield and days to maturity, plant height, number of branches, and number of productive nodes. The seed yield had no genotypic correlation with all agronomic characters observed. The genotypic correlation was only significant for plant height and number of productive nodes, number of branches and number of filled pods, as well as number of productive nodes and 100-seed weight. Therefore, the improvement of seed yield can be conducted through direct selection using the seed yield parameter or indirectly using the 100-seed weight.<br /><br /></p>

A field experiment was conducted comprising two varieties of mungbean, BARI Mung-5 (V1) and BARI Mung-6 (V2), and five levels of phosphorus fertilizer: triple super phosphate [Ca(H<sub>2</sub>PO<sub>4</sub>)] viz. T1 (control), T2 (42.5 kg P ha<sup>−1</sup>), T3 (85 kg P ha<sup>−1</sup>), T4 (127.5 kg P ha<sup>−1</sup>), and T5 (170 kg P ha<sup>−1</sup>). The experiment was organized in a randomized complete block design with three replications. V1 produced the highest number of pods per plant (7.65), whereas the maximum 1,000-seed weight (49 g) was produced by V2. The maximum plant height (30.89 cm), number of branches per plant (8.55), number of leaves per plant (19.05), number of pods per plant (10.25), pod length (8.95 cm), number of seeds per pod (9.11), 1,000-seed weight (48.17 g), and yield (1.05 t ha<sup>−1</sup>) were obtained from the T4 treatment. The interaction of phosphorus levels and varieties had a considerable effect on the growth, yield, and yield attributes of mungbean. The highest number of leaves (20.44) and number of pods (10.39) were obtained from V1 when 127.5 kg P ha<sup>−1</sup> (T4) was applied, whereas the maximum number of seeds per pod (9.25) and maximum pod length (9.09 cm) were obtained when  85 kg P ha<sup>−1</sup> and 42.5 kg P ha<sup>−1</sup>, respectively, were used. The highest number of branches per plant (8.87), 1,000-seed weight (52.83 g), and the maximum seed yield (1.14 t ha<sup>−1</sup>) were achieved from the treatment V2T4 owing to the interactive effect of phosphorus dose and mungbean variety.

The success of breeding programs depends on selection procedures and on the breeding methods adopted for selecting segregating populations. The objective of this study was to evaluate the efficiency of the Bulk method with selection in the F3 generation (BulkF3) compared to that of Bulk method as well as determine the most effective selection strategy in terms of genetic gain. Twenty segregating populations were selected by two methods. The 60 best families of each method were selected according to their average agronomic performance. An augmented block design was used. The following agronomic traits were evaluated: insertion height of first pod, plant height at maturity, number of branches and of pods per plant, 100-seed weight, and grain yield. For comparison of the methods, genetic component estimates, genetic gain and predicted breeding values were calculated using mixed models (REML and BLUP). The results showed the families obtained with the BulkF3 method were more productive, showed suitable plant height, a larger number of branches and pods, and higher 100-seed weight. The BulkF3 method was found to be an effective selection strategy for soybean improvement.

Twenty eight diverse landraces collected from various parts of North Eastern Region of India along with two checks were evaluated to study the diversity pattern among the genotypes on 17 morphological traits. High magnitude of genotypic coefficients of variation (GCV) and heritability coupled with high genetic gain were observed for average fruit weight, fruit yield per plant, number of fruits per plant, fruit length, number of branches per plant, number of seeds per fruit and 100 seed weight. However, these parameters were moderate for early fruit harvest and total soluble solids (TSS). Thirty genotypes were grouped into 6 clusters which showed intercluster D2 values ranging between 115.81 and 670.08. Grouping of genotypes of same location in different clusters indicated that the geographical diversity may not necessarily be related to genetic diversity. The cumulative contribution (82.28%) of fruit weight, 100-seed weight, number of branches per plant and fruit yield per plant to the total divergence indicate the importance of these traits in choice of parents for hybridization programme in cucumber.

A field experiment was conducted at the Agriculture Faculty Farm of Sebha University during the 2007/2008 and 2008/2009 winter seasons to study the agronomic performance of seven pea genotypes with different sowing dates in sandy soil. The experiment was laid out in a randomized complete block design (RCBD) using a split-plot arrangement with three replicates. The five sowing dates (30 October, 15 November, 30 November, 15 December and 30 December) were assigned to the main plots, while the seven pea genotypes (Ambassador, Pollon, MG130256, G22765-2c, 89-P-109-11, No. 252, Victory Freezer and Master B) were allocated to the sub-plots. The sowing dates had a significant effect on all the studied traits except seed protein content in both seasons. Early sowing (15 November) was better than the other sowing dates for all the traits except 100-seed weight. There were significant differences between the pea genotypes for all the traits in the two growing seasons. The Victory Freezer genotype surpassed the other genotypes for all traits except number of branches plant-1 in the second season, 100-seed weight and seed protein content. The highest values for number of branches plant−1 in the second season and for seed protein content were obtained for the G22765-2c genotype, while the maximum values of 100-seed weight were recorded for the MG130256 genotype. A significant interaction between sowing dates and pea genotypes was detected for the length of the period from emergence to initial flowering, number of pods plant−1, seed yield plant−1 and seed yield ha-1 in both seasons. The longest period from emergence to initial flowering was obtained for the Victory Freezer pea variety sown on 30 November, while the highest values of pods plant−1, seed yield plant−1 and seed yield ha−1 were gained by sowing the Victory Freezer pea genotype on 15 November.

Studies on genetic variability, correlation and path coefficient analysis were carried out with 38 accessions of cowpea (Vigna unguiculata L. Walp.) evaluated in two environments i. e. kharif 2013 (E1) and kharif 2014 (E2) at Research field of NBPGR, Regional Station Jodhpur, India. Analysis of variance revealed significant differences among the genotypes for all the traits. Genotypic coefficient of variation was highest for number of clusters per plant followed by number of pods per plant in both the environments. High broad sense heritability along with high genetic advance for seed yield per plant, 100 seed weight, pod length, number of pods per plant, peduncle length, number of clusters per plant, number of branches per plant and plant height indicated the presence of additive gene effects for these traits in cowpea. In both the environments seed yield per plant was positively correlated with 100 seed weight, pod length, number of pods per plant, number of clusters per plant, number of branches per plant and plant height. The highest positive direct effect registered by number of branches per plant followed by number of clusters per plant in E1 environment and by number of branches per plant followed by plant height in E2 environment. The traits like 100 seed weight, plant height, number of pods per plant number of clusters per plant and number of branches per plant were identified as selection criteria for obtaining good parental lines in cowpea breeding programmes.
