摘要: World cotton commerce is largely derived from Gossypium hirsutum and G. barbadense, two tetraploid members of a diverse genus (Gossypium) comprised about 50 diploid species distributed across America, Africa, Asia, Australia. A central issue in molecular genetics the genetic control development spinnable fibers, economic organ cotton. The observation that cottons transgress levels fiber yield quality has suggested polyploidy created novel opportunities for evolution. Development application comprehensive set DNA markers, other tools new avenues investigating development, questions
