The Strategy to Control Potato Late Blight by Transgenic Technology

Abstract

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
