| 摘 要： | 本文对甘蓝型油菜×蓝花子杂种Ｆ１继代６０代后的ＰＭＣ１）的细胞学进行了观察。结果表明：继代６０代后的该杂种再生植株的细胞组成较复杂，减数分裂存在多种类型。其中，中期Ｉ的完全不配对类型占４８．０％，后期Ｉ的１８—１８的染色体组分割极具特色。

| Abstract: | This paper deals with cytogenetics of the hybrid between Brassica napus and Raphanus sativus var. raphanistroides Makino after 60 generations. The results indicated that there were intricate cell ingredients in the regenerated plants of the hybrid and existed many types of meiotic division. The type of complete unpairing at MI had 48.0%, and it was characterized by chromosome set fractionation (18-18) at AI. |
