VARIABILITY OF CLEISTOGAMIC FLOWERS AMOUNT AT COTTON HYBRIDS DEPENDING ON INITIAL FORMS

It was determined that for the amount of inheritance of cleistogamous flowers type of plant branching is very important as well as the initial forms involved in the hybridization. The hybrid combinations involving lines with predominantly cleistogamous flower type indicators of dominance coefficient were negative with the incomplete dominance of the initial forms with a low number of cleistogamous flowers. The practical breeding for cleistogamous flower type, the line with mainly cleistogamous flower type and of complex originated lines LM-11 and LM-13 is recommended to use
