The study also revealed that from the tendency of resistant and susceptible genotypes to cluster together, it can be inferred that these genotypes share a common phylogenetic pathway and the resistancy and susceptibility to fusarium wilt may be due to mono or oligogenes which can in turn to be targeted using more efficient marker (molecular) systems.
The genes for these traits (okra leaf, trichomes and gossypol) have higher effect in terms of magnitude and are reported to be governed by oligogenes (Niles, 1980; Endrizzi et al., 1984).In view of the importance of these insect resistant traits there is a need for breeding varieties by incorporating the genes for these naturally conferring insect resistances in elite cotton varieties.
