The triploids (2n=39) had been obtained by the crossing of cultivated species G. hirsutum L. of the variety C-4727 (2n=52) with diploid species G. trilobum Skovsted (2n=26). The hexaploid amphydiploid (2n=78) had been synthesized by colkhisyting of triploid growing point. The introgressive line L-T had been obtained by four times crossing. By crossing of line L-T with varieties and lines the lines had been created combining best characteristics of parents: resistance to verticillium, high fiber quality.
