论述了定西在豌豆根腐病研究及抗病育种的进展,介绍了甘肃中部地区豌豆根腐病的主要致病菌是茄镰刀菌(Fusarium solani(Mars)Sacc)、豌豆丝囊霉(Aphanomyces euteiches)等8种病原真菌复合侵染引起的根腐综合症;通过选育抗(耐)根腐病品种是解决问题最经济有效环保的措施,先后培育出了不同生态类型的豌豆品种定豌1号到定豌5号,基本解决了生产中因根腐病导致的减产、绝收现象,这些品种在甘肃中部、宁夏南部的旱地农业生产中发挥了重要作用。
This paper discussed the research on the root rot of pea and the progress of disease-resistant breeding in Dingxi. The main pathogens of pea root rot in central Gansu were described as Fusarium solani (Mars) Sacc, Aphanomyces euteiches ) And other eight kinds of fungal pathogenic fungi root infection caused by complex infection; by breeding resistant (resistant) root rot varieties is the most cost-effective environmental protection measures to solve the problem, has developed a different ecological types of peas peas given pei 1 No. 5 to Ding Pei, basically solved the production cut-off caused by the root rot, the phenomenon of total yield, these varieties in central Gansu, Ningxia southern dryland agricultural production has played an important role.
