1987~1990年共鉴定5317份粟品种,筛选出对粟锈病中抗以上的品种47份,占鉴定数的0. 88%.经粟品种对粟锈菌的抗性研究表明:有的品种在不同环境条件下,抗病性反应不稳定;同一品种在粟孕穗期和始穗至开花期两个生育阶段的抗性无明显差异;粟锈菌在不同抗病类型粟上的潜育期一般相差1~2天,夏孢子堆大、小和病斑反应型也明显不同。
From 1987 to 1990, a total of 5317 millet cultivars were identified, and 47 cultivars of anti-rust resistance were screened out, accounting for 0.88% of the identification number. Studies on the resistance of millet cultivars to P. rust fungi indicated that some cultivars Under different environmental conditions, the disease-resistant response was not stable. There was no significant difference in resistance between the two cultivars at the booting stage and beginning to flowering stage of the same cultivars. A difference of 1 to 2 days, summer spore reactor large, small and lesion reaction type is also significantly different.
