Abstract:

Cucumber is the vegetable with highest yield among all the facility-grown vegetables in China. In recent years,the main epidemic diseases have had a serious impact on cucumber production. Utilizing molecular breeding techniques to improve selection efficiency,cultivating new resistant cultivars,and promoting their application is the most economical and effective way to control diseases and of great significance for the improvement of cucumber yield and food safety. In this paper,the research on molecular breeding of cucumber disease resistance was reviewed from the aspects of germplasm resources of resistant materials,mapping of resistance genes and QTLs,gene cloning and molecular mechanism analysis,and cultivation of new disease-resistant cultivars. Besides,the existing problems were analyzed,and the future work was prospected so as to provide reference for cucumber disease resistance breeding in the future.

Key words: Cucumis sativus, disease resistance, molecular breeding, research progress
