Purposefulness of using the performedfamilies 0–445, 0–580, 0–455 in the genetic and breeding researches for improving offiber output and the families of 0–580, 0–455, 0–520 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.
