    摘要:

    马铃薯孢囊线虫(PCN,potato cyst nematode)是马铃薯中重要的检疫性病害,可造成马铃薯减产80%。近年来,据报道西南地区多个马铃薯主产区发现马铃薯金线虫(Globoderarostochiensis)。为了我国马铃薯生产安全,筛选马铃薯孢囊抗性种质资源、选育抗性品种迫在眉睫。利用前人报道的抗性分子标记N146、N195、57R、TG689、Gro1-4-1和Gpa2-2,对云南省农业科学院保存的875份马铃薯种质资源进行马铃薯孢囊线虫抗性标记筛选。筛选到211份资源含有马铃薯金线虫抗性基因H1分子标记(N146、N195、57R和TG689),其中114份资源中同时含有4个分子标记;7份资源含有马铃薯金线虫抗性基因Gro1-4分子标记Gro1-4-1;237份资源中含有马铃薯白线虫抗性基因Gpa2分子标记Gpa2-2。本研究结果将为马铃薯孢囊线虫抗性育种提供技术支撑和材料基础。

    Abstract:

    Potato cyst nematode (PCN) is an important quarantine disease in potato, which can reduce the yield of potato by 80%.In recent years, it has been reported that the potato golden nematode (Globoderarostochiensis) has been found in several major potato producing areas in Southwest China.In order to ensure the safety of potato production in China, it is urgent to screen germplasm resources with cyst resistance and select resistant varieties.Using molecular markers N146, N195, 57R, TG689, Gro1-4-1 and Gpa2-2, 875 potato germplasm resources preserved by Yunnan Academy of Agricultural Sciences were screened for resistance genes to potato cyst nematode.211 resources were screened to contain H1 molecular markers (N146, N195, 57R and TG689) of the resistance gene of potato wireworm, of which 114 resources contained 4 molecular markers at the same time;Seven resources contain molecular marker Gro1-4-1 of potato golden nematode resistance gene Gro1-4;237 resources contain Gpa2-2 molecular marker of potato white nematode resistance gene Gpa2.The results of this study will provide technical support and material basis for the breeding of potato cyst nematode resistance.
