The location and variety had little influence on genetic differentiation of U. virens. The strains from same field have little difference in genetic variability and population differentiation, and there was no specific interaction between rice variety and U. virens.
大多数菌株相似性系数达0.79以上，说明湖北省稻曲病菌种群亲缘关系较近，地域性差异对种群分化的影响较小；来自不同品种上的稻曲病菌菌株之间的亲缘关系与水稻品种没有显著的关系。

目的研究亚洲大豆栽培品种地理群体的遗传多样性、特异性和群体分化。
参考来源 - 亚洲大豆栽培品种遗传多样性、特异性和群体分化研究The result implies the conservation strategies of this endangered plant. Because of the low level of genetic diversity and high level of population differentiation, promoting gene flow (via seed and seedling) among populations would be a practical effort of conservation.2.
研究结果对该濒危植物的保护有重要意义,考虑到低水平的遗传多样性和高水平的居群分化,通过居群间种子和幼苗的交换来促进基因流是可行的保护方案。
