Background: Green gram [Vigna radiata (L.) Wilczek] is an ancient and well known pulse crop of Asian countries. Specific traits should be considered for high yield in green gram as selection criteria in future breeding program.Methods: The investigation material comprised of 128 F6 RIL (Recombinant Inbred LINE) population sown at college farm, Professor Jayashankar Telangana State Agricultural University during Rabi-2019-20. The yield and yield attributes were recorded to conduct genetic variability, heritability broad sense (h2), genetic advance (GA) and genetic advance as % of mean (GAM).Result: Analysis of variance revealed significant differences among the RILs, indicating the presence of genetic variability for almost all the traits studied. High PCV and GCV estimates was noticed for number of pods per plant, seed yield per plant, number of cluster per plant and number of pods per cluster. High heritability along with high genetic advance as per cent of mean was observed for number of pods per plant, seed yield per plant, number of cluster per plant, number of pods per cluster, number of branches per plant, number of seeds per pod and plant height indicating the role of additive genes in governing the inheritance of these traits and could be improved through selection. The traits viz. seed yield per plant, number of pods per plant, number of clusters per plant and number of pods per cluster had recorded high PCV, GCV, high heritability along with high genetic advance as per cent of mean indicated these traits were less influenced by environment and possess high genetic variability. Hence these RILs would be suitable for green gram breeding programmes to develop improved varieties. The present findings of the RIL population will be useful for development of high seed yielding variety in green gram.

The present investigation was carried out with 24 progenies in F4 generation of interspecific cross derivatives of Vigna radiata cv. VBN(Gg)2 x Vigna mungo cv. Mash 114 to study the variability and association among the yield and the yield component traits. A set of 24 F4 progenies from the interspecific cross between greengram (VBN(Gg)2) and blackgram (Mash 114) formed the basic genetic material for the present investigation. Variability studies recorded high Phenotypic Coefficient of Variation (PCV) and Genotypic Coefficient of Variation (GCV) for the traits viz., number of branches/ plant, number of clusters/ plant, number of pods/ plant and seed yield /plant. High heritability (h2) along with high genetic advance as per cent of mean (GAM) were recorded for the traits, plant height, number of clusters/ plant, number of pods/ plant and seed yield/ plant. Association studies revealed that the trait number of pods/ plant alone recorded high direct positive effect on seed yield/ plant. The results indicated that high magnitude of variability was present among the interspecific progenies for these traits. The high heritability and genetic advance might be due to presence of additive gene action. Hence selection based on these traits might be effective for genetic improvement among the interspecific progenies of Vigna radiata x Vigna mungo. The study indicates that the trait, number of pods / plant should be given due importance in selection programme for seed yield improvement in the interspecific progenies of greengram and blackgram.

<p>Estimation of Genetic Variability and Correlation Among Early Maturity Mungbean Yield Components. Ratri T. Hapsari. Early maturity mungbean [Vigna radiata (L.) Wilczek] is very important to avoid drought stress, pest and disease attack as well as increase the index planting. The aims of this research was to estimate genetic variability and correlation. The genetic study included heritability, coefficient of genetic variability, genetic advance and correlation among yield components so that it can be used as selection criteria for early maturity mungbean. A total of 145 accessions of mungbean were tested at Muneng farm station in March-June 2010 using a randomized block design, with two replicates. Each accession was planted at 0.8 m x 4 m with spacing 40 cm x 10 cm, with two plants/hole. Fertilization was done by adding 50 kg urea, 75 kg SP36, and 75 kg KCl/ha, at the time of planting. The results showed that mungbean accesions had significant differences in all characters tested. The genetic variance value of all characters was broad with high broadsense heritability estimates, except for number of pods/ cluster and seed number/pod. Genetic advance of all characters were high, except for seed number/pod. The phenotypic correlation between 1000 seeds weight and pod length with seed yield were positive significant while plant height, flowering days, days to maturity, and number of pods per plant had negative significant correlation with its yield. Therefore, plant height, days to maturity, pod lenght, 1000 seeds weight and seed yield could be used as selection criteria based on estimating value of genetic variability, correlation with yield and economic value. There were five genotype which have index value above 20, i.e MLGV 0353, MLGV 0362, MLGV 0354, MLGV 0358, and MLGV 0351.</p><p> </p><p><strong>Abstrak</strong></p><p>Kacang hijau [Vigna radiata (L.)

A field experiment was conducted to study the genetic variability, heritability and genetic advance of 24 morphological traits and three biochemical traits in 47 genotypes of vegetable pea. The analysis of variance showed significant differences among genotypes for all the characters under study. Highest coefficient of variation was observed for number of podding nodes per plant and highest phenotypic and genotypic coefficients of variation were recorded for seed yield per plant followed by number of primary branches per plant and green pod yield per plant. Very high heritability estimates were observed for days to last pod picking (97.63) followed by plant height (97.40), days to first pod picking (96.78) and shelling percentage (95.56) while genetic advance as percentage of mean was found high for seed yield per plant (65.95) and primary branches per plant (58.40). High heritability along with moderate to high genetic advance was predicted in case of pod weight and number of seeds per pod, which indicated the role of additive gene action for the inheritance of these traits and therefore, selection could be used for improving these traits.

The experiment was conducted at the National Pulses Research Centre, Vamban, during Kharif 2020. F2 generation of four crosses was utilized in this study. Around 150-200 single plants per cross were used for observation. The traits viz., plant height, number of branches per plant, number of cluster per plant, number of pods per cluster, number of pods per plant, 100 - seed weight and seed yield per plant recorded high PCV, GCV, high heritability along with high genetic advance as per cent of the mean. It indicated that these traits were less influenced by the environment and possessed high genetic variability. Also, these traits had a positive and significant correlation with seed yield in most of the crosses. The trait number pods per plant recorded positive and high direct effects on seed yield. Hence, based on correlation and path analyses, the number of pods per plant can be considered as a selection index for seed yield improvement programme in blackgram. However, population-specific selection indices are preferred as the association of traits varies with the populations

A study was conducted to estimate genetic variability, correlation and direct and indirect effects of yield attributes on seed yield of fourteen Bangladeshi varieties of Brassica rapa. High heritability coupled with high genetic advance was recorded in a number of secondary branches plant-1, a number of siliqua plant-1 and a number of seeds siliqua-1 indicating the effects of additive genes in controlling the traits. Significant and positive association with seed yield plant-1 were observed in the number of primary branches plant-1, a number of seeds siliqua-1, while a negative association was found in days to maturity. The path analysis revealed that the days to first flowering, number of secondary branches plant-1 and 1000 seed weight were the main contributors to seed yield. The results suggest that days to first flowering, number of primary and secondary branches plant-1 and 1000 seed weight may be considered for selection to improve the seed yield in B. rapa.

The present investigation was undertaken to study the genetic variability, diversity through cluster analysis and correlation among yield attributing traits. The experimental material is comprised of 63 diverse germplasm accessions including three check varieties were evaluated in augmented design during Rabi 2015-16 at IIPR, Kanpur. In this study, totally nine traits, namely, days to fifty per cent flowering (DF), days to maturity (DM), plant height (PH), number of branches per plant (NBP), number of pods per plant (NPP), pod length (PL), seeds per pod (SPP), 100 seeds wt (g) (HSW) and seed yield per plant (g) (SYP) were recorded. The results exhibited that the analysis of variance noticed significant differences among the genotypes for all characters studied. The genetic variability parameter showed that phenotypic coefficient of variation (PCV) were higher than those of genotypic coefficient of variation (GCV) for all the traits studied. Higher GCV coupled with heritability and genetic advance as % mean was recorded for PH, NPP, HSW and SYP. Likewise, high heritability coupled with high genetic advance as % mean was recorded in DF, PH, NPP, PL, HSW and SYP. Trait association study revealed that the seed yield per plant exhibited significant positive correlation with NBP, NPP, NSP and HSW. In the same pattern, Euclidian clustering analysis displays 63 genotypes were grouped to two major clusters. From this investigation, it was observed that all genotypes showed sufficient genetic variability for the traits studied. The genotype such as EC400414, EC400398, ET8415 and EC540173 were superior to check varieties in terms of morphological and other agronomic traits. These genotypes could be utilized in breeding programme for improvement of specific traits.
