不同小麦品种(系)抗赤霉病程度分析

Analysis on the Scab Resistance Degree of Different Wheat Varieties( Lines)

为了明确小麦品种(系)之间对赤霉病抗性差异,制订适宜的防治措施,采用穗期单花滴注法人工接种赤霉病病菌,对不同小麦品种(系)抗小麦赤霉病程度及产量进行了鉴定分析。不同小麦品种(系)间抗赤霉病程度有差异,未发现免疫品种(系),其中周麦18、AF-01、AF-11对小麦赤霉病有较好的抗性,受感染后,产量分别达到5 588.89、4 572.22、4 600.00 kg/hm2。

The study aimed to confirm the wheat scab-resistance differences among wheat varieties （lines） to make appropriate preventive measures. The heading stage single flowers drip inoculation scab pathogen was used to identify different wheat varieties （lines） of wheat scab resistance and yield. Different wheat varieties （lines） There are differences in the degree of resistance to scab, it was found no immune varie- ties （lines）, among which Zhoumai 18, AF-01, AF-11 have better resistance on wheat scab, after infection, the yield reached 5 588.89 kg/hm2, 4 572.22 kg/hm2, 4 600 kg/hm2.
