Abstract
The article presents the results of an analysis of studies on the role and effectiveness of new synthetic amphidiploids {[(G. thurberi Tod. х G. raimondii Ulbr.) х G. arboreum L.] x G.hirsutum L.} and {[(G. thurberi Tod. х G. raimondii Ulbr. х G. arboreum L.) х G.hirsutum L.] х G.barbadense L.}, with interspecific hybridization and increased yield and length of cotton fiber. It was established that in plants of new families of interspecific hybrids obtained with the participation of the C-6524 variety of synthetic amphidiploids, the fiber yield increases from 0.2 to 3.9%, and the fiber length increases by 0.1-1.1 mm from the control. In new families of interspecific hybrids obtained with the participation of the S-4727 variety of synthetic amphidiploids, the fiber yield increases from 0.2 to 5.4%, and the fiber length increases by 0.2-1.1 mm from the standard. The new families selected by the yield and length of the fiber in the process of research according to their indicators, having a competitive ability among zoned varieties, can meet the production requirements for the quality of type III-IV fiber. With an increase in other economically valuable signs, families are recommended for creating new high-quality lines and varieties of cotton.
