英文摘要	Indica is not only an important rice subspecies widely planted in Asia and the rest of the world, but it is also the genetic background of the majority of hybrid varieties in China. Studies on genetic structure and genetic diversity in indica germplasm resources are important for the classification and utilization of cultivated rice in China. Using a genetically representative core collection comprising 1482 Chinese indica landraces, we analysed the genetic structure, geographic differentiation and diversity. Model-based structure analysis of varieties within three ecotypes revealed nine eco-geographical types partially accordant with certain ecological zones in China. Differentiation of eco-geographical types was attributed to local ecological adaption and physical isolation. These groups may be useful for developing heterotic groups of indica. To facilitate the identification of different ecotypes and eco-geographical types, we identified characteristic SSR alleles of each ecotype and eco-geographical type and a rapid index of discrimination based on characteristic alleles. The characteristic alleles and rapid discrimination index may guide development of heterotic groups, and selection of hybrid parents.
