GENETIC ANALYSIS IN FODDER LABLAB (LABLAB PURPUREUS L.)

Published on

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. To exploit 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.
