Purposefulness of using the performed families О-445, О-580, О-455 in the genetic and breeding researches for improving of fiber output and the families of О-580, О-455, О-520 to improve the fiber length on the dependence of their genotypes has been presented in this paper. In general, similarity of a high dominance of varieties in the positive indexes on the fiber output and fiber length in combination of various soil-climatic zones was noted.
