豌豆种植地区,从热带至寒带分布很广,在生产实践中,病害的种类不仅多,而且在局部地区危害严重和产量损失大。除使用药剂或耕作措施等积极防治外,比较经济有效的方法是抗病育种,而且不少有关研究者指出,豌豆不同品种的抗病性,与其抗病基因有密切关系。曾在我省一些豌豆产区,于五十年代末至六十年代所种植的引进豌豆品种,如保加利亚和多纳夫等,先后都有所扩种,但均因开花后的根腐病严重侵害,发生 Pea cultivation area, from tropical to cold distribution is very wide, in the production practice, the disease is not only more types, but also in a serious harm to local and yield loss. In addition to the use of agents or tillage measures and other active prevention and control, the more cost-effective method is to resist disease breeding, and many researchers pointed out that the pea resistance of different varieties are closely related to their resistance genes. In some pea producing areas in our province, pea cultivars introduced in the late 1950s and 1960s, such as Bulgaria and Donauv, have been expanded, but both have severe root rot after flowering Infringement occurred
