Study of the relations of interspecies hybridization of the parental forms with plant height in f1, fb and f2, f3 compounds of per branch of the first harvest (hs)

Abstract

Particular attention is paid to their genetic mechanisms during the interspecific hybridization using of G.hirsutum L. and G.barbadense L. species in the cotton plants. The study of the genetic foundations of chasmogamous and cleistogamous flower traits in solving the urgent problems facing the science of genetics and cotton breeding includes its technological processes, adaptation to the world standards, the actual problem of seed science, and basic solutions. In the interspecific hybridization of the parental forms, F1, Fb and F2, F3 compounds, the plant height and first branch of the crop (hs), fertile, resistant to various diseases, dominant specimens with a high predominance of fiber yield and fiber length, comb, gene collections and varieties are paid the main attention.
