GENETIC ANALYSIS IN FODDER LABLAB (LABLAB PURPUREUS L.)

Abstract

Genetic an~lysis of fodder yield and yield attributes in lablab with 6 X 6 diallel cross revealed the predominance of dominance genetic component for plant height, total leaf area, dry weight of stem and green fodder yield. The mean degree of dominance indicated over dominance for all the characters studied'. Dominant alleles were more frequent than recessive alleles in the parents for plant height, total leaf area, number of leaves, green fodder yield, dry matter production and crude protein content. Toexploit both the additive and nonadditive genetic components in lablab for fodder, the use of biparental mating in early generation among selected crosses or use of selection procedure such as diallel selective mating is possible.
