pollination, were investigated for genetic variations in flowering time, petal length and width, pistil length, and silique length and width. These reproductive characteristics of the strains were compared with those of ten other vegetables belong to Brassica campestris L.<BR>1. There was a significant variation among the Sugukina strains for flowering time with the maximum difference being 15 days.<BR>2. No significant difference was observed for flower size, whereas silique length and width varied significantly among strains with high heritabilities between two successive generations (rank correlations of 0.93 and 0.83, respectively). These results demonstrate that genetic heterogeneity exists among Sugukina strains for flowering time and silique size. Compared with other vegetables of the same species, the Sugukina strains tended to have larger flowers and siliqua.
