The indica and japonica differentiation resulted in significance of hybrid sterility and hybrid breakdown, which are barriers of gene flow between the two major subgene pools within O. sativa. Traditional classification of indica and japonica germplasm based on isozymes. Here, we report the identification of several random amplified polymorphic DNA (RAPD) markers that have alleles specific in indica or japonica varieties and thus provide a quick and accurate tool to distinguish japonica lines from indica ones. 关 键 词：特异性RAPD分子标记 亚种 水稻
