摘要/Abstract

摘要： 晚疫病是由致病疫霉菌(Phytophthora infestans)引起的病害，是限制马铃薯产业发展最严重的病害之一。采用传#br#统育种和化学农药等方法防治马铃薯晚疫病虽然早有研究，但至今收效甚微。基因工程技术的兴起为防治马铃薯晚疫病提供了新#br#的契机，并已取得了一定成效。但单基因抗性容易丧失、水平抗性应用难度大，要提高抗病基因的持久性，同时释放多个抗病基因，#br#人为提高田间抗病基因的多态性是目前可选途径之一。对各种防治方法进行了综述，通过转基因技术创建抗病基因近等混合系是#br#持久防治马铃薯晚疫病的首选可行方法，概述了其发展前景。

Abstract: Potato late blight is caused by Phytophthora infestans, which is one of the most serious threats to potato production. In previous research, it proved that it was difficult to control potato late blight by conventional breeding and chemical pesticides. There will be a new opportunity to control potato late blight due to the rise of gene engineering technology, and some success has been achieved. In order to improve the durability of resistance genes, one of the promising solutions for late blight control is to release several R genes simultaneously and artificially create a resistance polymorphism in the field, such as R gene polyculture. Through the comparison of various control methods, the strategy of R gene polyculture by transgenic technology is the first feasible method for controlling potato late blight, and the feasibility and prospects of create R gene polyculture were summarized in the article.

Key words: Potato, Llate blight, R gene polyculture
