小麦抗赤霉病种质资源鉴定与评价

摘要

A total of 260 different-source wheat variteis (lines) were evaluated in terms of scab resistance during the year of 2013-2014. The result showed that the immune germplasm and resistance(R) varieties did not exist, the resistance (MR) varieties accounted for 3.46% of the total for evaluation of wheat; the resistance (MS) varieties accounted for 16.33%, and most of the variteis were susceptible soybean varieties. The scab resistant of Ning wheat series which came from the middle and lower reaches of the Yangtze River region were more resistant than The Huai wheat series which didn,t come from the regions.%2013—2014年度对不同来源的260份小麦品种（系）进行赤霉病抗病性鉴定与评价。结果表明，鉴定品种中免疫或高抗（R）品种不存在；中抗（MR）品种占全部供鉴小麦的3.46%；中感（MS）品种占全部供鉴小麦的16.33%；大多数为感病品种。其中非小麦赤霉病重发区的淮麦系列品种抗赤霉病性相对较差，而赤霉病重发区的长江中下游麦区的宁麦系列品种较抗病。
