大豆矮缩病毒(SbDV)是黄毒科的成员之一，在日本北部大豆生产中造成严重的产量损失。我们此前发现，印尼的一种大豆品种。Wilis对SbDV有很高的抗性。虽然Wilis感染了SbDV，但与许多感病品种相比，症状总是轻微的，而且发病较晚。用71个重组自交系与感病日本品系杂交，利用数量性状基因座分析鉴定了野生稻对黑穗病病毒的抗性基因S。Toyota okomachi和一组已发表的简单序列重复(SSR)标记。Wilis对SbDV的抗性主要由连锁群A1上SSR标记Sat_271附近的单个QTL控制。该QTL解释了表型变异的79%。
Soybean dwarf virus(SbDV), a member of theLuteoviridaefamily, causes serious yield losses in soybean production in northern Japan. We previously found that an Indonesian soybean cv. Wilis had a high level of resistance to SbDV. Although Wilis is infected by SbDV, symptoms are always mild and develop considerably later compared with many susceptible cultivars. To identify the resistance gene(s) to SbDV in Wilis in a quantitative trait loci (QTL) analysis, we used 71 recombinant inbred lines derived from a cross between Wilis and the susceptible Japanese cv. Toyokomachi and a set of published simple sequence repeat (SSR) markers. The SbDV resistance in Wilis was mainly controlled by a single QTL located near the SSR marker Sat_271 on the linkage group A1. This QTL accounted for 79% of the phenotypic variance.
