MANIFESTATION OF HETEROSIS EFFECT BY TECHNOLOGICAL QUALITY OF FIBER IN INTRASPECIFIC AND INTERSPECIFIC HYBRIDS OF COTTON
In this article is apprisen effectiveness of heterosis by technological quality of fibers in intraspecific and interspecific hybrids of cottons. According the result of laborotary analysis the relative breaking load of fibers in intraspecific hybrids of cotton direct and reverse combinations by 0.4-0.5 g/t higher than those of parent forms. In intraspecific hybrids under consideration by 0.1-0.6 g/t higher than the paternal genotypes have and in comparison with the maternal - it is by 7.1-7.7 g/t higher. It gives possibility to conduct selection research in order to increase technological quality of cotton fiber.
