Genetic variability, correlation and path analysis in moth bean

Abstract

Genetic associations among 30 genotypes of moth bean were worked out for 12 characters. The genotypic coefficient of variation was highest for branches per plant followed by grain yield per plant, clusters per plant and pods per plant. High heritability estimates were observed for grain yield per plant, days to 50% flowering, days to maturity, plant height, branches per plant, clusters per plant, pods per plant and harvest index. The expected genetic advance as % of mean was high for grain yield per plant, branches per plant, clusters per plant and pods per plant. The correlation studies revealed high correlation of grain yield with pods per plant, clusters per plant, harvest index, branches per plant, days to 50% flowering, days to maturity and plant height.
