Assessment of Genetic Diversity for Yield Component Traits and Grain Yield of Blackgram [Vigna mungo (L.) Hepper]

Abstract

Due to its high nutritional content and ability to supply a diet rich in protein, pulses hold a special place in Indian agriculture. In contrast to the world's production of cereals, pulses are grown seldom in low-fertile soils under conditions of moisture stress, which eventually hides their actual yield capability due to inadequate management approaches. The current study's objective is to estimate the genetic parameters of 13 yield attributing traits in 20 genotypes of urd bean to choose more yield-contributed characters in urd bean. Number of pods per plant revealed high estimates of PCV, GCV and heritability. In the Metroglyph study, superimposition of genotypes was seen because to the near closeness of two variables used to display the genotypes. In this classification analysis made based on number of pods per plant and harvest index for all the 20 genotypes of urd bean form four complexes.  Out of 20 genotypes, 4 genotypes like IC-331226, IC-261173, IC-385718, and IC-426495 were recorded highest index score and fell into different complex, hence used as parents for getting good combinations for future hybridization programmes.
