Abstract:

Kam sweet rice is a special glutinous rice in Dong ethnic minority in the southwest of China. For centuries, according to local climate and special ecological environment, through the long-term natural evolution and artificial selection, they are famed for their native-bred glutinous rice using traditional farming methods. The authors reviewed the relation between kam sweet rice and original ecology traditional culture, their unique characteristics, and the evolution and differentiation etc, which would enrich and supplement our national rice genetic resources, elite variety breeding, germplasm resource utilization and protection of new varieties, and providing a reference value for modern molecular design breeding in rice.

Key words: Dong ethnic minority, kam sweet rice, evolution, Oryza sativa, germplasm resource, original ecology traditional culture

摘要：

香禾糯是我国西南山区以侗族等为代表的少数民族在原生态山间梯田里，根据当地特殊的生态和气候环境，完全采用传统农耕方式，经过长期自然演变和人工选择，世世代代传承至今的地方特色优良糯稻品系。本文综述了香禾糯与原生态民族文化的关系，香禾糯独特的优良性状及演变分化情况，以期为我国稻种遗传资源的丰富和补充、优良品种选育、新品种保护、种质资源创新利用，以及为现代水稻分子设计育种提供价值参考。
