为探明新疆桃抗根结线虫的种质资源价值,以实生钵苗为试材,采用人工接种2龄幼虫的方法,研究了新疆桃对花生根结线虫、北方根结线虫、南方根结线虫和爪哇根结线虫的抗性。结果表明:新疆桃高抗上述4种根结线虫,其实生群体内存在显著的抗性分离现象,对4种根结线虫的抗性均分离为免疫和高抗2种类型,侵入高抗型植株根系内的4种根结线虫的发育受到强烈抑制,以致完全无法产卵繁殖;新疆桃对花生根结线虫、北方根结线虫、南方根结线虫和爪哇根结线虫免疫株率分别为26%、20%、26%、12%。新疆桃是优异的抗根结线虫种质资源。 In order to explore the germplasm resources value of peach root-knot nematode in Xinjiang, taking the seedling of seedling as seed material, the method of artificial inoculation of second instar larvae was used to study the effects of Xinjiang peach root-knot nematode, root-knot nematode, Resistance of nematodes and root knot nematodes. The results showed that Xinjiang peach resistance to the above four kinds of root-knot nematode, the existence of the population of significant segregation of resistance, resistance to the four kinds of root-knot nematode were immune and high resistance to two types of invasive high-resistant The development of 4 kinds of root knot nematodes in the plant root system was strongly inhibited, so that they could not spawn at all. The immune strains of Xinjiang peach root knot nematode, root knot nematode, root knot nematode and javanicum were 26 %, 20%, 26%, 12%. Xinjiang peach is excellent resistance to root knot nematode germplasm resources.
