自从Blakeselee和Avery1937年报道用秋水仙素处理曼陀罗植株可以使染色体加倍后,Beasley1940年成功地应用这一技术克服了棉花远缘杂种不育。knight1955年报道,将二倍体亲本加倍后再与四倍体亲本杂交,可以克服杂交不孕。我国到70年代才见应用这一技术克服棉花远缘杂交不孕和杂种不育的报道。自1973年以来,我们结合棉花远缘杂交育种,对棉花多倍体的诱导、多倍体的形态特点、细胞学特征、育性变化以及在远
Since Blakeselee and Avery reported in 1937 that the water-soluble dietary supplement had been added to the water, Beasley used the so-called one-year cotton warp pack in 1940. Knight1955 report, the diploid parents and then tetraploid parents to double, you can overcome the cross-fertility. Until the 1970s, China saw the application of this technology to overcome the cotton distant infertility and hybrid sterility reports. Since 1973, we have combined cotton distant hybridization, polyploid induction of cotton, morphological characteristics of polyploidy, cytological characteristics, changes in fertility and far
