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。
Through the identification of 905 different types of rice resources from 47 countries in the natural ecological conditions of Guiyang, the results showed that 95% of the varieties were short and semi-dwarf, with more types of late maturing during the whole growth period. The agronomic characters The comprehensive evaluation of disease resistance and stress resistance showed some differences in the same traits of different geographical origin materials, but also showed that the comprehensive traits were good, disease resistance and stress resistance were strong, and could be used directly by Guizhou rice production Material for breeding classification.
