美国农业研究局最近成功育成一系列抗根瘤线虫玉米新品种。这些新品种玉米不但可使在其根部产卵并进行孵化的多数线虫很快死亡 ,并且能延长幼虫发育为成虫的时间和减少危害作物的成虫数量 ,从而达到抵抗线虫的目的。这种玉米新品种主要可抵御危害作物的黄麻根瘤线虫和沙生根节 The American Bureau of Agricultural Research has recently successfully bred a new breed of root-knot nematode corn. These new varieties of corn not only allow most nematodes that spawn and hatch at their roots to die quickly, but also extend their larvae’s development into adults and reduce the number of adults that endanger the crop, thus achieving resistance to nematodes. This new maize variety is primarily resistant to root-knot nematodes and saprophytic root-knot nematodes that endanger crops
