摘要

We studied how much the green hypocotyls (g), green sitique (gs), and hairy silique (hy) genes are maintained in wild radish populations. Three genotypes of g in each population were not significant from the standpoint of the Hardy-Weinberg's ratio.The F_2 of both crosses segregated the normal and detrimental genes into the expected monogenic ratio of 3 : 1. As for the gs, it was different compared to the green hypocotyl gene. The frequency of gs was low in general and was lower than that of g. The population differentiation (G_(ST)) value of gs was about twice as much as that of g. Wild radish populations showed a close relationship between their distributions of detrimental genes and geographical positions. Judging from the present distributionof the wild radish populations, the high level of gene flow in wild populations is mainly caused by seed dispersal via sea currents. Nevertheless, the locally uneven distribution of three detrimental genes among populations indicates that selection hasacted differently on these three characters.
