Abstract: Rosaceae fruits are very important for fruit production in China and worldwide. Recently，significant advances in regeneration and genetic transformation of Rosaceae have been achieved and applied to various Rosaceae trees and fruits. However，the factors affecting the process of regeneration and transformation have not been reviewed in detail. This paper reviews recent progress in the regeneration pathway，factors affecting regeneration，genetically modified species and main traits，and the factors affecting Agrobacterium-mediated genetic transformation. The differences between species of Rosaceae fruits are emphasized，and the trends and areas for future studies are highlighted.

Key words: Rosaceae fruit tree, regeneration, genetic transformation, affecting factor
