Abstract:
The white flower and yellow flower mutant materials,which drived from the selfing offspring of the artificial synthesized Brassica napus’s S0 generation were used as the parents to build the BC1 and F2 segregating populations.By the methods of χ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 a pair 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.
