报导了两个稻瘟菌株CH63和TH16的杂交后代在36个水稻品种上的致病性分离、遗传分析以及无毒基因组成的分析结果。78个子囊孢子菌株中呈现显著的致病性分离，共出现71种致病类型，在不同品种上分别出现1：1、1：3、3：1、1：7、1：15和15：1等的无毒性／毒性分离，表明供试菌株对不同品种的无毒性／毒性是一个或多个基因控制的。

From a cross-cultural perspective, Chinese authors'high commitment to propositions can be attributed to their solidarity with their readers and a collectivist cultural orientation.
