【摘要】 对2004-2006年度参加国家或部分省(市)区域试验的193个新选育的大豆品种进行了针对大豆花叶病毒主要流行株系SC-3和SC-7的抗性鉴定。结果表明:中作119、东大2号、中作017020、中作00-683、03鉴31等20个品种对2个株系都表现为抗侵染,约占参试品种总数10%;铁豆37、东大4号、铁96001-7、密选2号、东大7号等36个品种对SC-3株系表现为抗侵染,占参试品种总数的19%;晋遗46号、徐9302-186、晋遗39号、石豆412 4个大豆品种对SC-7株系表现为抗侵染,占参试品种总数的2%。除此之外,鲁9594-3、浙4074、中作J4015,汾豆72等品种虽然对2个株系表现为系统感染,但病情指数相对较低,表明这些品种对于大豆花叶病毒的扩展有一定抗性。这些不同类型的抗性品种既可用于大豆生产,也可作为抗源用于抗病新品种选育和与抗性相关的研究。更多还原

【Abstract】 The resistance to Soybean Mosaic Virus(SMV) of 193 cultivars from the Soybean National Regional Test and Local Regional Test in 2004-2006 was evaluated.The results showed that 20 cultivars such as Zhongzuo119,Dongda 2,Zhongzuo017020,Zhongzuo00-683,03jian31 et al were resistance in infection to both strains SC-3 and SC-7.36 cultivars such as Tiedou37,Dongda 4,Mixuan 2,Tie96001-7,Dongda7 et al were resistance in infection to strains SC-3.4 cultivars such as Jinyi46,Xu9302-186,Jinyi39 and Shidou412 were resistance in infection to strains SC-7.In addition to cultivars with resistance in infection to SMV,some cultivars such as Lu9594-3,ZhongzuoJ4015,Fendou72 et al were resistance to development of Soybean Mosaic Virus.These cultivars can not only be used directly in soybean production,but also can be used as resistance resources in breeding programs.更多还原
