摘要

马铃薯晚疫病是一种造成重大损失的疾病,在非洲中部和东部,损失率高达 75%以上。有鉴于此,为了限制合成杀菌剂的过度使用,使用抗病品种是一个更好的选择。本研究的重点是对中部和东部非洲在提高马铃薯抗晚疫病能力方面已经开展的工作进行综述,以了解总体情况。为此查阅了76份文件,包括67篇科学文章、8本书籍和一个网页。文献显示,这些地区马铃薯抗晚疫病能力的提高主要基于整个育种计划中的常规方法。这些研究主要由国际马铃薯中心领导。本综述涉及晚疫病造成的产量损失、Phytophthora infestans的生物学、晚疫病管理方法、抗晚疫病遗传学、中部和东部非洲抗晚疫病遗传资源、马铃薯抗晚疫病筛选方法和育种方法。

Potato Breeding for Late Blight Resistance in Central and East Africa
Potato late blight is a disease of great loss, which can go beyond 75% in Central and Eastern Africa. With this in mind, in order to limit the excessive use of synthetic fungicides, the use of resistant varieties is a better alternative. This study focuses on the synthesis of works already carried out in the improvement of potato resistance to late blight in Central and East Africa in order to have a general overview. For this purpose, 76 documents were consulted, including 67 scientific articles, eight books, and a web page. The literature has shown that the improvement of potato resistance to late blight in these areas is mainly based on conventional methods throughout the breeding scheme. These studies are mainly led by the International Potato Center. This review covers yield losses due to late blight, the biology of Phytophthora infestans, late blight management methods, the genetics of late blight resistance, genetic resources for late blight resistance in Central and East Africa, screening methods and breeding approaches for potato late blight resistance.
