GENETIC VARIABILITY ESTIMATES OF QUANTITATIVE AND QUALITATIVE TRAITS IN BLACK GRAM
Journal Title: International Journal of Agriculture Sciences - Year 2016, Vol 8, Issue 40
Abstract
Black gram (Vigna mungo L.) has the potential of supplying a major portion of dietary protein demand and restoring the soil health at the same time. Research on genetic variability studies of the genotypes may increase the opportunity to exploit its potential which will help to meet the demand of high yield and nutrition supply. In this connection, an experiment was conducted to estimate the genetic variability of quantitative and qualitative traits in 24 lines of black gram. Genetic parameters like genotypic and phenotypic variance, coefficient of variation, heritability and genetic advance were estimated. Except for days to maturity a significant variation was noted for all the traits. The genotypes were highly variable for cluster plant-1, pods plant-1, seeds pod-1 and seed yield plant-1. In general phenotypic coefficient of variability was greater than their corresponding genotypic coefficient of variability. Broad-sense heritability was higher for all the traits except for days to 50 per cent flowering and branches plant-1. High heritability coupled with high GAM was observed for the characters pods cluster-1, pod length, test weight, seeds pod-1 and seed yield plant-1 indicating that these characters are mainly controlled by additive genes and selection of such traits might be effective for the improvement of grain yield. The genotypes with dull seed luster were highly frequent than shiny seed luster. Globular seeds producing genotypes were more frequent than those producing drum shaped and globular seeds.
