我国小麦品种抗条锈性丧失问题发生较迟,是解放后应用杂交品种“碧蚂1号”出现的一个新问题。截至目前,我国小麦品种抗条锈性的丧失,大体上可归为三批;即五十年代一批,六十年代一批和七十年代一批。五十年代以“碧蚂1号”为代表。这一品种1952年大面积推广,1957年完全丧失抗锈性。同一时期丧失抗锈性的还有“西北54”、“西北丰收”、“农大183”等。六十年代以“玉皮”、“甘肃96”、“陕农9号”、“南大2419”为代表。这些品种一般是1957年开始推广,1964年以前先后丧失了抗锈性。同一时期丧失抗锈性的还有“西农6028”、“中农28”、“西北612”、“西北134”、“陕农1号”、“农大311”
The problem of loss of resistance to stripe rust occurred in Chinese wheat varieties occurred later, which was a new problem appeared after the liberation of the hybrid breed Bi-1. Up to now, the loss of stripe rust resistance of wheat cultivars in China can be generally classified into three batches; that is, the batch of the 1950s, the batch of the 1960s and the batch of the 1970s. The fifties “Bi Ma 1” as the representative. This variety was extensively popularized in 1952 and completely lost its rust resistance in 1957. During the same period of loss of rust resistance are “Northwest 54”, “Northwest harvest”, “Nong 183” and so on. Sixties to “jade”, “Gansu 96”, “Shannon 9”, “Nanda 2419” as the representative. These varieties are generally promoted in 1957, before 1964 has lost the rust resistance. During the same period of loss of rust resistance are “Westong 6028”, “Zhongnong 28”, “Northwest 612”, “Northwest 134”, “Shannong 1”, “Nongda 311”
