摘　　要：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。An analysis of 1630 accessions of Yunnan indigenous rice collected from 82 counties showed that 724 of them fell into the category of ' poly - phenotype resources' , accounting for 44% of the total, with a poly - phenotype coefficient (X) of 1.75, a diversity index (H) of 1.34 and a correlation coefficient (r) between X and H of 0.90 * *. They were found to distribute mainly in the 4 prefectures of Simao, Lincang, Banna and Dehong covering 9 counties, which are located in the southern edge and southwestern Yunnan and are inhabited mainly by the Dai, Nani, Lahu and Wa nationalities.
