不同小麦品种（系）抗耐黄矮病鉴定与评价

１９８９～１９９４年田间人工鉴定１１７３份小麦品种（系）材料，对小麦黄矮病的反应有不同程度差异。症状表现高抗的是中４，中５，忻４０７９，Ｙ９０１３６—４，Ｙ９０７８１—１４等；表现抗病的是临汾５１４，临汾５１８，忻３１８５等；表现耐病的是临汾６０１０，平阳２６１，临辐５１２３４，临旱７７（４）７等。症状表现高度感病，千粒重降低明显，生产中应谨慎使用的品种是烟１６０４、长治８６—３７９８、临汾８７—７０９３、平阳２８７等。

Field Screening and Appraisal of Wheat Varieties for Resistance to Yellow Dwarf Disease

Field scrrening work of 1173 wheat varieties of resistance to wheat yellow dwarf virus in 1989～1994 showed that levels of reaction to wheat yellow dwarf virus among wheat varieties were different. Chun─4, Chun─5, Xin4079, Y90136─4 and Y90781─14 were high resistance. Linfen514, Linfen518 and Xin3185 were middle resistannce. Linfen6010, Pingyang261,Linfu51234 and Linhan77(4) 7 were tolerance. Yan1604, Linfen87─7093, Changzhi86─3798and so on were high susceptible, of which 1000 kemel weight reduce. We suggest that these varieties chould be used in caution in production. careful use in production.
