GENETICS OF YIELD, YIELD ATTRIBUTES AND THEIR IMPLICATIONS IN BREEDING OF COTTON (GOSSYPIUM HIRSUTUM L.)

Published on

A 9 X 9 diallel cross analysis indicated predominance of additive variation for seed cotton
yield per plant and six other yield attributes including bolls per plant. Genotype Laxmi was
a good general combiner for five of the seven traits including bolls per plant. OS-4 and
OS-56 were also good combiners, the latter showing significant gca effects for seed cotton
yield per plant and bolls per plant. Potential cross combinations were also identified for
giving good yields. Three crosses, OS-56 X RR0-417, RR0-425 X DP-I635 and OS-4 X
FORN-l based on sca effects were considered ideal for exploitation of heterosis.
