小麦品种抗赤霉病性的遗传是属于多基因控制的数量性状。过去对小麦抗赤霉病性的研究多以静止的方法进行,仅以接种后某一固定时期植株发病情况为指标,这不能全面反映小麦品种抗赤霉病扩展性的遗传特征。作者发现,不仅不同品种对赤霉病扩展的反应不同,而且同一品种不同时期在抗扩 The inheritance of resistance to scab in wheat cultivars belongs to the quantitative trait controlled by multiple genes. In the past, the studies on the resistance of wheat to Fusarium head blight were mostly carried out in a static manner. Only the incidence of plant disease at a fixed period after inoculation was taken as an indicator, which could not fully reflect the genetic characteristics of the scab resistance of wheat cultivars. The authors found that not only the different varieties reacted differently to the expansion of scab, but also the different varieties
