中国大豆品种对大豆花叶病毒（SMV）病抗病性鉴定结果

本试验是在日本国农林水产省东北农业试验场作物开发部大豆育种研究室进行的。试验在网室内采用人工接种鉴定的方法,用日本的大豆花叶病毒(SMV)病五个生理株系(SMV—A.—B.—C.—D.—E)对我国125份大豆品种进行鉴定。 鉴定结果认为,对SMV—A株系具有抗病性的品种占26％;对SMV—B株系具有抗病性的品种占6％;对SMV—C株系具有抗病性的品种占16％;对SMV—D株系具有抗病性的品种占15％;对SMV—E株系具有抗病性的品种占8％。在供试品种中对SNV五个株系表现全抗的品种只有铁丰18,抗两个以上株系的品种有27个,占供试品种的22％。

EVALUATION OF RESISTANCE OF CHINESE SOYBEAN CULTIVARS TO SMV

The test was conducted in soybean breading laboratory of exploiting, Northeast Agricultural Experimental Farm in Japan.125 varieties of Chinese soybean cultivars were tested for resistance to 5 Japenese SMV stains(SMV-A, SMV-B, SMV-C, SMV-D,SMV-E) with inoculation.The results showed that the cultivars resistent to SMV-A,SMV-B, SMV-C, SMV-D, SMV-E were 26%, 6%, 16%, 15% and 8%, respctively. Among these varieties, only Tiefeng No. 18 was resistant to all the five strains.27 varieties were resistant to more than 2 strains.
