Abstract:: Characters and their correlations of different fruit shapes fruits of 171 apple strains of reciprocal cross between ‘Royal Gala’ and ‘OBIR-2T-47’ were studied.The results showed that the variation of single fruit weight was larger，while variation of transverse diameter was smaller among strains with different fruit shapes.When longitudinal diameter or transverse diameter of different shape fruit increased，their fruit weights would increase significantly or highly significantly.When flesh firmness and soluble solid content increased，a down trend of single fruit weight would appear.The smaller fruit shape index，such as oblate fruit，or larger，such as oval and long conical fruit，the larger the single fruit weight.The shape index of long conical fruit increased the most significantly when its longitudinal diameter increased，and the shape index of short conical fruit increased most significantly when its transverse diameter increased.
