利用54个微卫星标记对虹鳟鱼产卵时间进行了QTL分析。连锁试验已进行了回交家庭的交叉春季和秋季产卵污渍在加拿大安大略。我们已经绘制了13个QTL标记的产卵时间代表7个连锁群。这些QTL标记中有8个来自5个连锁群，在两个采样年内表现出可重复的效果。这些结果表明，这一特点是高度多基因的虹鳟鱼。
We have used 54 microsatellite markers to search for quantitative trait loci (QTL) associated with spawning time in rainbow trout (Oncorhynchus mykiss). Linkage tests have been conducted in a backcross family produced by crossing spring and fall spawning stains in Ontario, Canada. We have mapped thirteen QTL markers for spawning time representing seven linkage groups. Eight of these QTL markers from five linkage groups show repeatable effects in two sampling years. These results suggest this trait is highly polygenic in rainbow trout.
