Reciprocal hybrids between the stem eelworm of the red clover and those of onion, straw berry, parsnip, parsley and narcissus were obtained. Observations were conducted on the state of hybrid and control populations within 10 generations. A partial genetic and physiologica incompatibility of crossed forms of stem eelworms which manifests itself to a different extent in various combinations of parental pairs, was revealed. The red clover eelworm is a biological race of the collective species Ditylenchus dipsaci, which is at a certain stage of intraspecific differentiation.
获得了红三叶草茎线虫与洋葱、草莓、欧洲防风草、欧芹和水仙茎线虫之间的正反交杂种。对10代以内的杂种群体和对照群体的状况进行了观察。揭示了茎线虫杂交形式的部分遗传和生理不相容性，这种不相容性在不同亲本对的各种组合中表现程度不同。红三叶草茎线虫是茎线虫复合种的一个生物小种，处于种内分化的某个阶段。
