Abstract

Graphical analysis was performed in 8 lentil genotypes crossed in a half diallel manner. The analysis revealed over-dominance for the traits under study. PL 6 had maximum concentration of dominant alleles for seeds/pod, pods/plant, plant height, and days to maturity. For 100 seed weight, days to 50% flowering and primary branches/plant parent PL 7 had maximum concentration of dominant alleles. For pods/cluster and days to maturity parent 6 had maximum concentration of dominant alleles. Use of such superior cultivars with greater proportions of dominant alleles can be focused focus for development of hybrids in lentil breeding programme. Thus hybridizing parent PL 6, PL 7 and L 4188 with other lines are suggested to yield superior crosses. Hayman’s genetic ratios also confirmed the major contribution of non-additive component in governing traits.
