Various crosses at a cotton were carried out with participation of mutants. The various circuit of a hybridization of mutants with different attributes dilates an oppotrunity of reception of a genetical diversification of selection-valuable forms. With the help of mutagens there are built wiltresistant mutants of the cotton, and it is shown that they may serve as donors of wiltresistant genes. There was shown the opportunity of reception homogeneous families by mutant trait used chemical mutagens in early generations of the cotton, that opehs new ways for acceleration useful donors creation. There was created the genetic collection of mutants and mutant-hybrids, which are used in various selection establishments. There were created such varieties as Garabah-1, Garabah-2, Garabah-3 and Garabah-4.
