1987～1991年对全省各大豆育种单位育成的新品种(系)在未审定推广之前统一进行了抗灰斑病鉴定。这些品种是区域试验正进行中的品种,抗病性鉴定可供推广参考。在151份品种(系)中鉴定出高抗材料26份,占供试品种(系)的17.22％,抗病材料14份,占供试品种(系)的9.27％,中抗材料36份,占供试品种(系)的23.84％。分生理小种测定发现有6份抗5个生理小种以上的品种(系)。统计分析表明,品种(系)的不同部位发病程度有一定的相关性。
1987 ~ 1991 on the province’s soybean breeding units of new varieties (lines) in the unverified unified anti-gray spot identification. These cultivars are currently undergoing regional trials and disease resistance identification is available for promotion. Among 151 varieties, 26 were identified as high resistant materials, accounting for 17.22% of the tested varieties (lines), 14 resistant materials, accounting for 9.27% of the tested varieties (lines), 36 of medium resistant materials, Accounting for test varieties (lines) of 23.84%. Sub-physiological race determination found 6 anti-5 physiological races over the varieties (lines). Statistical analysis showed that the breeds (lines) of different parts of the degree of disease have a certain correlation.
