为了在小麦多品种、条锈菌多小种体系中研究小种间的相互关系,1995年9月至1997年5月在田间设置方块圃,以全感、水平抗性和垂直抗性三种不同抗病类型的6个品种及条中29、水源11致病类型I与混合小种(条中29:水源11致病类型I=1:1)三类小种组合为试材,对各品种-小种组合的流行速率进行方差分析。结果表明:在多数品种上,条中29与水源11生理小种间存在互作关系,表现为协同作用,且混小种的流行速率明显高于单小种的流行速率。
In order to study the interrelationship among races in wheat multi-races and stripe rust races, a square nursery was set up in the field from September 1995 to May 1997, with total resistance, horizontal resistance and vertical resistance The results showed that there was no significant difference among the six cultivars with different disease resistance types and in the strains 29, the pathogenic type I of water source 11 and the mixed race (the pathogenic type I of water source 11: I = 1: 1) Variance analysis was performed on the prevalence of breed-races. The results showed that in most varieties, there was an interaction between the races 29 and the races 11, which showed a synergistic effect, and the prevalence of races was significantly higher than that of the races.
