摘要: 胜利油菜(B.napus,L.var.oleifera,D.C.)同源异源八倍体〔4n(8x)=79〕具有一般同源多倍体所共有的特征,染色体组型为 aaaacccc 中期Ⅰ分裂相为: (0—2)_Ⅰ+(28—38)_Ⅱ+(0—5)_Ⅳ。减数分裂中表现有染色体组分割的异常进程,在植物染色体工程与进化遗传的研究中具有重要意义。

Abstract: Ⅰ.Cytological studies have shown that the karyotype of theartificial auto—allooctoploid synthesized from napus variety victory has76 chromosomes in the root tip cells and 38 bivalents during meiosis.The karyotic formula observed is as follows:(0-2)Ⅰ+(28-38)Ⅱ+(0-5)ⅣⅡ.The phenomenon of complemen
