Creation of selected items with high fiber yield and length based on cotton composite hybrids

The wide range of possibilities using double, complex and double crossing methods in cotton has been studied selection research. As a result the use hybridization, valuable traits varieties different genetic origin can be collected single genotype short period time. Because hybrids created on basis cross-breeding, variability quantitative characters is manifested large scale, possibility extensive appears these hybrid populations. It important to various breeding selection, which are widely used other agricultural crops. transgressive variation occurring composite hybridization cotton, increase isolating recombinants, source new variations, gives opportunity create with positive set economic time, confirmed In article, it stated that correct parental pairs method for improvement fiber yield length creation cotton. particular, effectiveness T-3377, T-3378, T-3379 varieties, achieving results terms was highlighted.
