ESTIMATION OF GENETIC PARAMETERS THROUGH GENERATION MEAN ANALYSIS IN BREAD WHEAT

Published on

Estimates of gene effects based on analysis of generation means were obtained for four
yield traits, namely, grains/spike, grain weightof3 spikes, yield/plant and l00-grain weight
in several crosses of breadwheat (Triticum aestivum L. em Thell). The contribution of
additive gene effects (d) were important in the inheritance of number of grains/spike and
l00-grain weight, whereas the dominance gene effects (h) contributed significantly for
grain weight of 3 spikes and yield/plant. Among the epistatic effects, additive x additive
interactions was of considerable importance for all the characters.
