甘薯抗黑斑病种质资源的研究及育种利用

Study Progress and Perspective of Black Rot Resistant Germplasm in Sweetpotato

甘薯黑斑病(black rot)是危害甘薯严重且普遍发生的病害,生产上主要采用综合防治方法进行防治,其中选育抗病性品种是防治甘薯黑斑病最经济、有效的措施。长期以来人们围绕甘薯抗黑斑病种质资源进行了多方面研究,本文系统地概述了甘薯抗黑斑病种质资源鉴定、筛选,以及甘薯对黑斑病的抗性遗传特点和抗黑斑病种质资源的育种利用,并展望了甘薯抗黑斑病资源与育种的研究前景。

Sweetpotato black rot（Ceratocystis fimbriata Ellis et Halsted） is one of the major restrictive factors in sweetpotato production,and which has caused serious yield losses and quality decrease in the world,it is very difficult to eradicate this disease.The integrated control systems are the main measures to prevent this disease.It was pointed out that application of the resistant varieties was most economic and effective method approach to control this disease.So studies on black rot of sweetpotato resistant were carried out for many years.Describes the identification,screening and evaluation for resistance to black rot of sweetpotato germplasm,and resistance identified inheritance pattern and the genetic character,and breeding utilization of black rot resistant germplasm in sweetpotato were introduced.The perspectives and advice of study for resistance to black rot in sweetpotato have been prospected in this paper.
