📄 Abstract

In this article the analyzed F1 plants of hybrid combinations studied on inheritance of fiber color, in interspecific F1 subsp. Ñ?аniculatum x subsp.ruderale f.parnat (tan fiber) combination, an intermediate, i.e light tan color fiber was observed, while in F2-plants 1:2:1 ratio was noted by fiber color. In studied reciprocal F1, subsp. Ñ?аniculatum x subsp.ruderale f.parnat (tan fiber) hybrid plants, analogical results were noted. F2 plants, a separation was observed in terms of day length requirement at a ratio of 15:1, the plants of the 15th part were observed as long-day non-demanding plants, and in the 1st part the plants were long-day demaning. In hybrid plants where such a separation rate was studied, it was also found that the polymer genes were inherited under the non-cumulative effect.
