Abstract:

Apple is a model plant for resistance gene research in fruits. This paper reviewed the structure characteristics of apple disease and insect resistant gene and gene mapping; summarized the research progress made in resistances to major apple diseases, such as scab, powdery mildew, fire blight, woolly apple aphid, etc.  It also expounded the application of molecular marker technology in this research area and carried out discussion about the existing problems and solving methods.

Key words: apple；QTL；resistant gene
