在甘肃天水县汪川设立了小麦条锈菌的周年病圃,圃中病菌基本上可不断繁殖,实现周年循环。抗病性各种不同的38个品种,在病圃中经历了1979—1984年五年鉴定,结果指出:1.病圃可用于区分垂抗和可能水抗品种,前者抗病性逐年明显减弱,而后者则在一定范围内波动而无明显的变异。2.病圃中小种组成基本上可反映在地区的小种组成,且能有较早侦查或监测新小种发生发展的能力。周年病圃值得进一步改进,以使之成为鉴定持久抗性和监测新小种发展的有力手段.
In Tianshui County, Gansu Wang Chuan set up the annual sick wheat rust garden, nursery bacteria can basically continue to reproduce, to achieve the anniversary of the cycle. The results showed that: 1. The nursery can be used to distinguish between vertical and potential water-resistant varieties, the former disease resistance decreased significantly year by year , While the latter fluctuate within a certain range without obvious variation. 2. The species composition of the nursery can basically reflect the races of races in the area, and can detect or monitor the development of new races earlier. Anniversary nurseries deserve further refinement to make them powerful tools for identifying long-lasting resistance and monitoring the development of new races.
