摘　　要：水稻是中国重要的粮食作物之一,而东北三省是我国重要的商品粮基地。常规育种技术已经不能满足人们对水稻产量及品质的追求,分子标记以其独特的优越性正在广泛地应用到东北水稻的各项研究中。本文从东北水稻抗瘟性分子研究、耐冷性分子研究、直立穗型研究、种质资源遗传多样性及籼粳分化研究4方面进行综述,旨在查明东北水稻分子育种现状及存在的问题,为系统地开展东北水稻分子育种研究指明方向。Rice is one of the important crops in China. The three northeast provinces is the important commodity grain base in China. Conventional breeding technology already cannot satisfy the pursuit of people on rice yield and quality, the molecular marker has been widely used in the studies of the northeast rice. This article summarized from four aspects： rice blast resistance research, cold resistance, erect panicle type, differentiation of indica and japonica and genetic diversity re- search. This article finds out the current situation and existing problems of molecular markers in three northeast provinces. This article indicates the direction for developing the northeast rice molecular breeding research systematically.
