Genetic studies on mote index, pollen sterility and earliness in interspecific cotton hybrids

Abstract

Hybrids between four divergent varieties of Gossypium hirsutum and eight of G. barbadense were evaluated for three components of commercial importance, mote index, pollen sterility and earliness in their F1 generation. It was found that the former two components were predominantly under the control of additive gene action. The studies brought out the possibilities of selecting for fertile and early-maturing hybrids with the incidence of motes. American Nectariless, K 3400 SB 289 E, SB 1095-6 were found to be desirable parents and the crosses of the former two as female with the letter two as male parents were found to possess all the desirable characters
