摘　　要：本研究对2007-2013年收集到的云南省傈僳族种植的56份地方稻资源的18个重要农艺性状进行全面调查与综合分析。结果表明,云南南部傈僳族种植的地方稻品种多样性要高于北部地区,且这批地方稻资源中有色稻占比大,达到50%且主要是红米资源。12个数量性状的多样性指数为1.68~2.06,6个描述性性状的多样性指数为0.60~1.16,数量性状的多样性指数明显高于描述性性状。主成分分析结果表明,与株型和产量紧密相关的性状为影响其表型多样性的主成分因子。从56份地方稻种资源中筛选出的红根细、雪山谷、细陆凤、矮脚细、冷水白谷、红谷、掉谷、叶盖谷、糯谷、白壳红米、俄嘎谷等特色和优异资源可供后续精准鉴定与研究利用。18 important agronomic traits of 56 rice landrace resources planted by Lisu nationality were collected in Yunnan province during 2007-2013 and were comprehensively investigated and analyzed in this study.The results showed that the variety diversity of rice landrace planted by Lisu nationality was higher in southern Yunnan than northern Yunnan,and colored rice resource was rich,especially for red rice,accounted for 50%of the germplasms collected.The diversity indices of quantitative traits were significantly higher than the diversity indices of descriptive traits,with the former varied in 1.68-2.06 and the latter varied in 0.60-1.16.Results of principal component analysis indicated that the traits tightly related to plant type and yield were the main factors affecting the phenotypic diversity.The unique and superior resource including Honggenxi,Xueshangu,Xilufeng,Aijiaoxi,Lengshuibaigu,Honggu,Diaogu,Yegaigu,Nuogu,Baikehongmi,Egagu selected from 56 rice landraces can be used for further precise identification and utilization.
