Abstract Taking the ic male sterile AB lines type I of yellow head Chinese cabbage with anti -

clubroot and orange head Chinese cabbage lines LH as the test materials the ic relations between the
head colors of orange and yellow and the genotypes of clubroot - resistance and fertility of orange head lines

were studied through cross backcross and sibling mate. The experimental results indecated clearly that orange
