摘　　要：对云南热区212份传统陆稻品种的17项数量性状进行了分析,结果表明:云南热区陆稻表现出丰富的形态和遗传多样性,多样性指数在2.277～2.326之间,变异系数在3.67%～49.24%之间,变异系数和多样性指数的变化趋势相反;通过聚类分析,云南热区陆稻品种被分为三个类群,其中类群I为单株产量低的类群,占供试品种的43%,类群 为单株产量中的类群,占供试品种的26%,类群 为单株产量高的品种类群,占供试品种的31%。Data of seventeen quantitative characters of two hundred and twelve uplandrice in tropical Yunnan were analyzed to determine the morphoagronomic characters diversity The results are as follows.Diversity in morphology of the uplandrice breeds in tropical Yunnan were discovered by analyzed, the diversity index was between 2277 and 2326, the variant coefficient was between 367% and 4924% The trend of the change of the diversity index and the variant coefficient was opposit The breeds were divided into tree types,in which 43 percent belonged to type Ⅰ,26 percent belonged to type Ⅱ,and 31 percent belonged to type Ⅲ The results showed that the diversity of uplandrice in tropical Yunnan was abundant
