Abstract
Evaluation of seven varieties of barley and F1 progenies of their half-diallel set, at 5⋅0 cm plant to plant spacing in 1973 and of the parents, F1’s and F2’s at 5⋅0 and 15⋅0 cm spacings in 1974 revealed that both years as well as spacings had significant effect on yield and other characters. The year interaction was significant for ears/plant, 1000-grain weight and plant height. The spacing interaction was significant for ears/plant (in F1 and F2 both) and 1000-grain weight (in F, alone). Partitioning significant interaction variances into general and specific combining ability components indicated that GCA effects were no less susceptible to the environmental interactions than SCA effects. The F1 and F2 generations were also significantly different for yield, ears/plant, 1000-grain weight and plant height. Each generation progenies showed significant variance regarding most of the characters. In general a decrease in the relative magnitude of SCA variance was observed in F2 generation.
