自1982年春开始,为利用太谷核不育小麦建拓抗赤霉病基因库,进行了小麦抗赤霉病资源的鉴定筛选工作。在连续5年的鉴定中,肯定了:于同一鉴定条件下,不同品种感病程度差异显著;通过接种鉴定,筛选抗源是有效的。但是,在鉴定中发现,同一品种在不同年份、不同播期,甚至同一播期的不同小区间,感病程度有明显差异。这说明影响小麦赤霉病发生发展的因素是多方面的,除了与病原菌数量及寄主生育期有关外,受环境条件影响很大。
Since the spring of 1982, Taigu resistance wheat germplasm resources have been identified and screened by Taigu nuclear sterile wheat. In five consecutive years of identification, affirmed: under the same identification conditions, different varieties of significant differences in susceptibility; through inoculation identification, screening of anti-source is effective. However, in identification, it was found that there was a significant difference in susceptibility between the same breed in different plots of different years, different sowing dates and even the same sowing date. This shows that the impact of wheat head blight development and development of many factors, in addition to the number of pathogens and the host growth period, the environmental conditions are greatly affected.
