Bulked segregant analysis (BSA) was adapted to identify RAPD markers linked to dwarf gene Dsl. Totally 1041 primers were screened and only one polymorphic band S470.416 was found linked to the Dsl locus with a map distance of 9.2 cM.

• 采用群分法(BSA)筛选了1041条RAPD引物，找到了一个与Ds1基因连锁的RAPD标记S470.；416，与Ds1的遗传距离为9
