Study on Genetic Variability and Correlation in Blackgram (Vigna mungo L. Hepper)

Author(s): Kondagari Hemalatha, Sapna S Lal and Gabrial M Lal
Abstract: The present investigation was conducted to examine the 25 blackgram genotypes along with one check (T-9) to study the genetic variability, correlation. The observation were recorded randomly selected plants to each treatment and replication for 12 quantitative characters viz., days to 50% flowering, days to maturity, plant height, number of branches per plant, clusters per plant, pods per plant, pod length, seeds per plant, seed index, biological yield per plant, harvest index, seed yield/plant to estimate the variability, heritability and genetic advance as % mean, correlation among seed yield and its related traits. Analysis of variance showed highly significant differences among 25 blackgram genotypes for 12 quantitative characters studied. Maximum genotypic and phenotypic variance was recorded for harvest index, plant height and pods/plant. Maximum GCV and PCV were recorded for harvest index, pods/plant and seed yield /plant. High heritability was recorded for pods/plant, biological yield/plant, days to maturity, days to 50% flowering, harvest index, seed yield/plant. High heritability coupled with high genetic advance as percent of mean was recorded for pods/plant. Correlation coefficient analysis revealed that seed yield/plant exhibited significant and positive correlation both at genotypic and phenotypic level with harvest index and pods/plant.
