| dc.description.abstract | Availability of genetic variation for productivity per se traits in the working germplasm is a prerequisite for breeding crops and blackgram is no exception to this. Blackgram germplasm comprising of 88 accessions with three checks Rashmi, T-9 and DU-1 were evaluated in randomized complete block design (RCBD) at the experimental plots of Department of Genetics and Plant Breeding, University of Agricultural Sciences, Bengaluru. Data were collected on nine quantitative traits. The estimates of broad-sense heritability as well as expected GAM were higher for clusters plant-1, pods plant -1 and seed yield plant-1 than those for other traits. The accessions were grouped into nine clusters based on K-means clustering. Quantitative traits means of genotypes included in nine clusters differed significantly for three out of nine quantitative traits, while trait variances were homogenous for all the nine QT’s. Evaluation of 12 promising genotypes across environments representing three different dates of sowing during 2017 indicated significant genotype × environment interaction for seed yield plant-1 based on AMMI model. The genotypes, RU-16-10, IC-261182 and RU-16-11 with lowest estimate of AMMI stability value (ASV) and Stability index (SI) were identified as stable across three dates of sowing, while BG-2 and LBG-20 were found specifically adapted to August sowing for most of the QTs. | en_US |
