国际马铃薯中心在中国设立的研究项目主要集中在抗晚疫病材料的引进、评价和利用 ;晚疫病菌生物学特性的研究及晚疫病的综合防治研究。自中国与国际马铃薯开展科技合作以来 ,已引进了近 30 0份抗晚疫病的马铃薯种质资源 ,包括杂交种子、试管苗和薯块。从中筛选出了一些可直接用于生产的抗晚疫病材料 ,从引进的杂交实生种子组合中也筛选出了一些新的品种 ,并利用这些资源与国内品种资源进行杂交 ,从中培育出新的抗性品种 ,极大地减轻了晚疫病对我国马铃薯生产的影响。为研究晚疫病菌的生物学特性及其对瑞毒霉的抗性 ,从国内马铃薯主产省区收集了 2 0 0多个菌株 ,并对生理小种和抗药性进行鉴定 ,所保存的菌株为进一步研究晚疫病打下了良好的基础。以利用马铃薯品种抗性为基础的综合防治研究工作已开始在中国进行 ,重点放在基因与环境的互作、预测预报和特定农业生态区综合防治配套技术上
The research projects set up by IUCN in China focus on the introduction, evaluation and utilization of late blight resistant materials, the biological characteristics of late blight fungi and the integrated control of late blight. Since the start of scientific and technological cooperation between China and the international potato, nearly 30 0 potato germplasm resources for resistance to late blight have been introduced, including hybrid seeds, test-tube seedlings and potato cakes. Some of them were screened out for their resistance to late blight, and some new varieties were also screened from the introduced hybrid seed combinations, and these resources were used to cross-fertilize with domestic varieties to cultivate new anti-late blight Sexual breeds, greatly reducing the impact of late blight on China’s potato production. In order to study the biological characteristics of Phytophthora infestans and its resistance to T. reesei, more than 200 strains were collected from the major potato producing provinces and autonomous regions of China, and the physiological races and drug resistance were identified. The strains Which laid a good foundation for further research on late blight. The research on integrated control based on the resistance of potato varieties has started to be carried out in China, with emphasis on the interaction between gene and environment, forecasting and supporting techniques for the comprehensive prevention and control of specific agro-ecological zones
