摘  要:
经田间调查分析,稻粒黑粉病在水稻不育系D汕A和珍汕97A上的病穗率与病粒率之间的关系(简称P-S关系)均可用指数函数描述,分别建立了两个不育系上的P-S关系模型。协方差分析表明两回归方程的截距间有显著差异,并建立了两不育系的P-S关系综合模型。

摘  要:
The relationship between the diseased panicle rate and the diseased seed rate (P-S re-lationship)of rice kernel smut (Neovossia horrida) on D shuan A-line and Zhengshuan 97 A-line were studied through field investigation. The results showed that the P-S relationship of the disease on the two A-lines might be described with exponential functions,and the P-S relationship models of the two A-lines were established. Analysis of covariance showed that there was a significant difference between the two regression intercepts, and the integrative P-S relationship model was established.
