摘要
水稻恶苗病（Ｇｉｂｂｅｒｅｌｌａｆｕｊｉｋｕｒｏｉ）是常见的水稻病害，对水稻生产威胁很大。１９９１～１９９２年作者用芽期接种方法和花期接种方法，鉴定了４２个水稻品种（品系）对恶苗病的抗病性，结果表明，芽期和花期接种均表现抗病或中抗的品种有哈８０—４－１、松粳２号、嫩交９０－０３８、藤系１４０、恢粘、松８８－１２、东８６１３、龙花０４６等２１份；芽期和花期接种均表现为感病或中感的品种有东农４１５、东农４１７、龙花８３—０７９、合江２１、嫩交９０—４７、哈８０—４等。此鉴定结果可供选用品种时参考。
By means of inoculation at stages of budding and flowering,resistances of 42 rice varieties (lines)to bakanae disease were evaluated in 1991 and 1992. The results showed that rice varieties having presented middle- resistance and resistance at both stages were Har 80 - 4 - 1 ,Songgeng 2,Nenjiao 90 -038,Tengxi 140,Huinian,Song 88 - 12,Dong8613,Longhua 046,etc. 21 in all. Rice varieties having prasented susceptibility or middle - susceptibility at both stages were Dongnong 415,Dongnong 417,Longhua 83 - 079,Hejiang 21, Nenjiang 90 - 47 and Har 80-4.
