1997～ 1998年对不同地区送鉴水稻广亲和材料进行了亲和性鉴定、分类与亲和谱分析。经鉴定广亲和性为“中”级以上的材料共 12份 ,其中 :T46 1、16 11、6 30 0 4、零轮、86 7s-15份材料的广亲和性为“优”级。作亲和谱测验的 4份广亲和性“优”级材料 ,其中 3份亲和谱等级为“宽广” ,1份为“中等”。 From 1997 to 1998, affinity identification, classification and affinity spectrum analysis of broad compatibility materials of rice in different regions were conducted. A total of 12 materials were identified with a wide compatibility of “middle” or above, among which T46 1,16 11,6 30 0 4, zero round, and 86 7s-15 materials were “good” . Four affinity affinity “excellent” materials were tested for affinity spectrum, of which three were “broad” and one was “medium”.
