ABSTRACT
|
Inheritance pattern of sympodia
per plant, plant height, bolls per plant, seed cotton yield and seed
oil content of cotton was assessed using diallel crossing model in which
six genotypes B-557, Culture 728-4, MNH156, B-1850 (ne), Culture-604-4
and MNH147 were crossed in all possible combinations. The results from
scaling tests for the adequacy of additive-dominance model indicated
that sympodia per plant, plant height, bolls per plant, seed cotton
yield and seed oil content were partially adequate for further genetic
analysis. Sympodia per plant, plant height, bolls per plant and seed
cotton yield and were controlled by additive genes, whereas over-dominance
was prevalent in seed oil content characteristics. Narrow sense heritability
for plant height, bolls per plant and seed cotton yield suggested that
these parameters could effectively be improved through selection in
the early segregating generations.
