摘要
在马铃薯晚疫病生理小种的鉴定中 ,经常出现结果不合理的现象 ,这时应通过单基因和复合基因鉴别寄主的发病情况反复相互验证 ,并增加重复次数 ,才能得出正确的结论。试验证实马铃薯晚疫病菌的生理小薯不是异质的 。
On the identification of physiological races of Phytophthora infestans,some unreasonable results usually occurred.True conclusions would be made if we mutual verified repeatedly by the disease case between monogenes identifical host and multigenes identifical host,and increase the repeats.This results showed that the physiological races of Phtophthora infestans was homogeneity,not of heterogeneity.$$$$
