摘　　要：以人工合成甘蓝型油菜S0代花色嵌合体自交后代的白花及突变的黄花株系为材料,构建BC1和F2分离群体,通过目测及卡方测验的方法对其花色遗传规律进行了分析。结果表明:该花色突变体是由1对不完全显性基因控制的质量性状遗传,白花(WW)对黄花(ww)表现为不完全显性,并通过与前人对甘蓝型油菜花色变异研究的结果进行比较,分析了花色变异的来源和可能的原因。The white flower and yellow flower mutant materials,which drived from the selfing offspring of the artificial synthesized Brassica napus＇ s S0 generation were used as the parents to build the BC1 and F2segregating populations.By the methods ofχ^2 test and visual inspection,genetic rule of flower color was analyzed and drew the conclusion that the flower color mutants were qualitative trait inheritance,which was controlled by apair of incomplete dominant genes,with white flower versus yellow flower showing incomplete dominant.Besides,by comparing the results of the previous studied on the Brassica napus flower color heredity,possible cause of the flower color variation were analyzed.
