通过对分布于82个县市的1 630份中国云南保存的地方稻种资源多种表现型现象进行分析,结果共有724份 稻种资源是具有多种表现型现象的资源,即多型性资源,多型性资源的比例为44.0％,多型性系数X为1.75,多样性 指数日为1.34,X与H的相关系数r=0.90**。多型性资源的地理分布主要集中在思茅、临沧、版纳和德宏4个地州, 以墨江、景洪、龙隆、永德、普洱、孟连和云县等7个县(市)为中心的地带,即云南多型性稻种资源主要集中分布在南 部边缘及滇西南地区的野生稻分布区、稻种资源富集区和陆稻的主要种植区。分布地区是傣族、哈尼族、拉祜族和佤 族等少数民族的主要聚居地。云南稻种资源的多种表现型现象与当地的地理和民族密切相关。
Through the analysis of the variety of phenotypic phenotypes of 1 630 wild rice germplasm stored in Yunnan, China, distributed in 82 counties and cities, a total of 724 rice germplasm resources are characterized by many phenotypic phenotypes, namely, polymorphic resources , The proportion of multi-type resources was 44.0%, the coefficient of polymorphism X was 1.75, the index of diversity index was 1.34, the correlation coefficient of X and H was 0.90 **. The geographical distribution of multi-type resources is mainly concentrated in 4 prefectures of Simao, Lincang, Banna and Dehong, with seven counties (cities), such as Mojiang, Jinghong, Longlong, Yongde, Pu’er, Menglian and Yunxian, As the center, that is, the genus of Yunnan polymorphic rice is mainly distributed in the wild rice distribution area, the paddy rice resource-rich area and the main planting area of the Upland rice in the southern edge and the southwestern Yunnan. The distribution area is the Dai, Hani, Lahu and Wa national minorities and other major settlements. The multiple phenotypic phenomena of Yunnan rice resources are closely related to the local geography and ethnic groups.
