“…The moderate heritability was recorded for days to flower initiation (59.10), total number of pods plant -1 (54.90), harvest index (44.00) and number of cluster plant -1 (30.60) signifying that selection of these traits are in a condition to accumulates more additive gene leading to further improvement of their performance (Table 2). Similar findings were reported for seed yield plant -1 by Raturi et al, [20], Kumar and Katiyar [16], Payasi (2015), Keerthiga et al, [21], Perera et al, [22]. Ahmad et al, [23], Anand et al [24] for number of pods plant -1…”

Greengram is India's most significant legume crop, and because there is relatively little genetic variety, increasing productivity demands increased attention in research for the development of superior cultivars. During Kharif 2020-21, an experiment was conducted to the evaluation of the genetic parameters for yield and their associated attributes for thirty-nine Mungbean genotypes. Using a Randomised Block Design (RBD), all genotypes were sown in three replications. The observations on various quantitative characters were recorded, and the genetic parameters, PCV, GCV, heritability(bs), and genetic advance, along with the analysis of variances, were estimated. According to ANOVA, almost all genotypes exhibited significant variances for all characters. The highest GCV and PCV was found to be pod length (cm), number of pods cluster-1, number of primary branches plant-1, biological yield plant-1 as well as seed yield plant-1. The heritability was recorded high for pod length (cm) followed by number of primary branches plant-1, number of pods cluster-1, days to pod initiation, number of seeds pod-1, days to 50% flowering, seed yield plant-1, biological yield plant-1, number of effective pods plant-1. The character’s days to flower initiation, total number of pods plant-1, harvest index and number of clusters plant-1 revealed medium genetic advance. High heritability(bs) coupled high genetic advance as percent of mean was observed for pod length (cm), number of branches plant-1, number of pods cluster-1, days to pod initiation, number of seeds pod-1, days to 50% flowering, seed yield plant-1, biological yield plant-1 and number of effective pods plant-1.

“…These results are in correspondence with Rao et al, (2006), Makeen et al, (2007), Kumhar and Choudhary (2007), Nand andAnuradha (2013), Zuge et al, (2019) and Asari et al, (2019) for days to 50% flowering and days to maturity. Perera et al, (2017) for days to maturity. The results obtained for PCV and GCV showed that there is considerable possibility of further improvement and by appropriate selection for these characters and development of high yielding variety can take place.…”

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.

“…Mungbean ( Vigna radiata L. Wilczek) is one of the most important legume crops in Asia as an affordable source of protein (25.00–28.02%) that is easy to get (Lucilla et al., 2017; Nair et al., 2012; Perera et al., 2017). This plant grows and produces well in various soil types and altitude below 500 m asl (Wahyudin et al., 2015), tolerant to drought (Ghanbari & Javan, 2015), and potential for cultivation in low light intensity such as intercropping with higher canopy plants (Sundari & Mutmaidah, 2017).…”

Genotype × environment interaction (G×E) of harvest period should be involved to assess the suitability of mungbean (Vigna radiata L. Wilczek) for monoculture or intercropping cultivations. This research was aimed to study the effect of G×E interactions on phenology and synchronous maturity, the change of genetic parameter estimates, and the stability of harvest period in mungbean. The study was conducted in Bogor, Indonesia, from December 2017 to October 2018 in four environments: wet season, monoculture (WS.M) and intercropping (WS.I); dry season, monoculture (DS.M) and intercropping (DS.I). Ten mungbean genotypes were evaluated in monoculture and intercropping with sorghum [Sorghum bicolor (L.) Moench] cultivar Numbu using a randomized complete block design with three replications. The phenological traits, namely days to flowering, days to the first harvest, days to 90% harvest, plant height, number of productive branches, seed weight per plant (SWP), and the synchronous maturity traits, namely harvest period, degree indetermination of plant height (DDh1), degree of indetermination of harvest period (DDd2), were observed. The results showed that the G×E interaction effect was highly significant (p < .01) for all phenological and synchronous maturity traits except DDd2. Phenotypic expression of all traits, except SWP and DDh1, were largely controlled by the genetic factor (h 2 bs > 59.83%). Kefa, Kawur, VR480B, Lom2, MLB, Vima 2, VR10, VR60 were stable (b i = 1), VR05 was sensitive (b i = 1.70), and No.129 was insensitive (b i = 0.66) and suitable for monoculture in the dry season. The GGE biplot showed Kefa as a stable genotype with the shortest harvest period. Mungbean selection for synchronous maturity can use harvest period trait in monoculture at dry season.
