摘　　要：通过对９０５份来自４７个国家不同类型稻种资源在贵阳自然生态条件下的鉴定结果表明：株高９５％的品种属矮和半矮秆型，全生育期中迟熟类型偏多；农艺性状与抗病性、抗逆性综合鉴定表现出不同地域来源材料存在同一性状上的某些差异，但也表现出综合性状好、抗病抗逆性强，可供贵州水稻生产直接利用或以之作材料供育种分类利用。Agronomic traits of 905 rice varieties introduced from 47 countries were identified and evaluated in Guizhou. The results showed that a number of elite with excellent genes such as high yielding, strong restoring to CMS, tolerance to diseases and pests or cold stress, especially from IRRI, Japan, India and other countries, were screened out. Those genetic materials to be utilized for rice breeding and other research were reserved safely in Guizhou.
