河北省生产推广种植小麦品种对麦红吸浆虫抗性鉴定及抗性风险评价

Identification of Resistance to Sitodiplosis mosellana Gehin and Resistance Risk Evaluation of Produced and Spreaded Wheat Varieties in Hebei Province

2012年利用田间抗性鉴定方法,针对河北省生产上推广种植的55个小麦品种,进行了对麦红吸浆虫的抗性鉴定及抗性风险评价。结果表明:不同小麦品种对麦红吸浆虫的抗性存在明显差异,明确了目前河北省生产上推广种植的55个小麦品种对麦红吸浆虫的抗性,其中,河农6049、石新828、济麦22、良星99、良星66和石麦12号6个品种为农艺性状好、高产、抗性稳定的高抗品种。并依据各抗性类型品种在生产上的种植面积,对各抗性类型品种在生产上的抗性风险进行了评价。

The resistance identification and resistance risk evaluation of wheat Sitodiplosis mosellana Gehin were studied using 55 wheat varieties which produced and spreaded in Hebei Province by field resistance identification methods in 2012. The results showed that there were obvious differences on the resistance of different wheat varieties to wheat Sitodiplosis mosellana Gehin. The resistance to wheat Sitodiplosis mosellana Gehin of 55 wheat varieties were made clear, among them Henong 6049, Shixin 828, Jimai 22, Liangxing 99, Liangxing 66 and Shimai No. 12 with good agronomic traits, high yield and stable resistance. According to planting area of wheat varieties of various resistance types, the resistance risk of different resistance type varieties were evaluated.
