摘要
对油菜品种奥罗 (Oro)与诸葛菜 (Orychophragmusviolaceus)杂种F3代种子 ,作根尖染色体观察发现 :在共计 1 89粒种子中 ,全部细胞具有 3 8条染色体的种子数是 1 62粒。根尖细胞染色体为混倍体的种子数是 2 7粒。在混倍体根尖中 ,具有 3 8条染色体的细胞占 64 .3 % ,具有 3 1条染色体的细胞占 2 2 .1 % ,还有少量细胞具有 2 4、1 9、1
Cytological studies on F 3 plants from hybridization between Oro,a oil rape variety,and Orychophragmus Violaceus were done through chromosome observation of root tip cells.It was found that among 189 kernels of seeds,all the cells of 162 of them had 38 chromosomes,and the cells of rest seeds had various chromosome numbers,say, they are mixoploids.In the root tip cells of the mixoploids,the chromosome number was 38(to 64.3% of the mixoploid),31(to 22.1% of the mixoploid),24、19、12、etc.respectively.
