Genetic Parameters and Diversity Analysis in Blackgram (Vigna mungo L. Hepper) for Seed Yield Characters

Abstract

Pulses occupy a very unique position in Indian agriculture by virtue of the fact that they are highly nutritious and provide a protein-filled diet via food. As compared to the cereal production globally, pulses are being produced sporadically in low fertile lands having moisture stress condition which eventually conceal its true yield capacity to its poor management practices. The aim of the present study uses to estimate the genetic parameters of 13 yield attributing characters traits in 20 Black gram genotypes with the view to select for better yield contributed characters in Black gram. Analysis of variance showed significant differences for all the 13 characters. Seed yield per plant exhibited high estimates of PCV, GCV and heritability. Super—imposition of genotypes was observed in Metro glyph analysis because of close proximity two variables taken for plotting the genotypes. In this classification analysis made based on biological yield and harvest index for all the 20 genotypes formed 4 complexes. Out of 20 genotypes 4 genotypes like KU-99-16, KU-96-8, KU-48 and KU-303 were recorded highest index score and fell into different complex, hence used as parents for getting good combinations for future hybridization programmers.
