摘要: 陆地棉的核型公式为2n=4x=52=30m+20sm(4SAT)+2st(2SAT); 染色体绝对长度平均3.40μm; 臂比值最大与最小的分别是4.02和1.14,平均1.77;随体3对,分别位于第12、19和26对同源染色体的短臂上;最长与最短染色体的比值为2.36;其核型属于Stebbin的2B类型。
Abstract:Karyotype formula of Gossypium hirsutum L.was 2n=4s=52=30m+20m (4SAT)+2st (2SAT); and its absolute lengths of chromosomes averaged 3.40μm; arm ratio differed from 1.24 to 4.02,with the mean value of 1.77; three pairs of satellite chromosomes; the ratio of the longest to the shortest chromosomes was 2.36; and the karyotype belonged to 2B in Stebbin’s classification.
