摘要
应用构建的NJRIKY(科丰1号×1138-2)大豆重组自交家系群体，对大豆根重QTL进行8次重复的随机区组分析；以该群体所构成的遗传连锁图谱为基础，采用复合区间作图法（Cartographer V. 1.21）检测到3个与根重有关的QTL位于连锁群N3-B1和N6-C2上。其中rw1在N3-B1的端距离是66.31cM，位于A520T～ACCCAGO5 区间，rw2和rw3分别在N6...
马拉硫磷对中华稻蝗种群遗传结构的作用Impacts of Malathion on Population GeneticStructure of Oxya chinensis
马拉硫磷 中华稻蝗 种群遗传结构 死亡率差异 等位酶
2008/1/8
摘要
将中华稻蝗(Oxya chinensis)注射1.5g/L的马拉硫磷，24h后死亡率为56%。用等位酶电泳确定死亡与存活个体在多态性基因座Pgm和Me上的基因型，并比较各基因型的死亡率差异。结果表明：在Pgm基因座上，马拉硫磷对具有不同基因型的中华稻蝗个体存在选择性致死作用，但是在Me基因座上未观察到类似选择性致死作用。在基因座Pgm上，Pgm-ab 基因型个体死亡率最高（80%），Pgm...
