【摘要】 对棉花三种杂种进行了细胞水平的核型分析,得出结论:三种杂种[A2×G1]×[AD]1的染色体数目为2n=4x=52,核型公式为2n=4x=52=2M+44m(2SAT)+6sm(2SAT),核型类型为1B。三种杂种[A2×G1]×[AD]2的染色体数目为2n=4x=52,核型公式为2n=4x=52=44m(2SAT)+8sm(2SAT),核型类型为2B。更多还原

【Abstract】 The karyotype of tri-species was analyzed on the lever of cells.It showed that the chromosome number of tri-species is 52.The karyotype formula of tri-hybrid[G　arboreum×G　bickii]×G　hirstum is 2n=4x=52=2M+44m(2SAT)+6sm(2SAT).The type of karyotype is 1B.The karyotype formula of tri-hybrid [G　arboreum×G　bickii]×G　barbadense is 2n=4x=52=44m(2SAT)+8sm(2SAT).The type of karyotype is 2B.更多还原
