山西农业大学等单位的研究人员经过六年的艰苦攻关,对棉花远缘杂交的研究终于获得了突破性的进展。其中陆地棉与瑟伯氏棉杂交,居于国内领先;亚洲棉与比克氏棉杂交,跻于国际先进行列。他们用四倍体栽培种陆地棉与二倍体野生瑟伯氏棉杂交,获得了异源六倍体杂交棉;用二倍体栽培种亚洲棉与二倍体野生种比克氏棉杂交,获得了异源四倍体杂种;用陆地棉与墨西哥半野生种杂交、陆地棉与亚洲棉杂交、亚洲棉与陆地棉杂交,均获得了可育的
Shanxi Agricultural University and other units of researchers after six years of painstaking research, the study of distant cotton hybrid finally made a breakthrough. Among them, Upland cotton hybrids with Cerberus cotton, living in the leading domestic; Asian cotton hybrids with Beech, among the advanced ranks in the world. They crossed the tetraploid cultivated species of G. hirsutum with diploid wild Cerberus hybrids to obtain alloderm hexaploid hybrids; crossed with diploid cultivars Asian cotton and diploid wild species Bk cotton, Heterotopic tetraploid hybrids were obtained. Heterotopic tetraploid hybrids were obtained. Heterotopic tetraploid hybrids were crossed with Mexican semi-wild species,
