Abstract: Analyzing the berry shapes of grape germplasms can provide a good basis for understanding the berry shape characteristics and breeding parent selection. In this study，820 grape germplasms were selected（286 through field surveys，534 from《Chinese grape》and《Chinese grape varieties》）. The type of different berry shapes and varieties of grape，the distribution of the fruit weight and its correlation with fruit diameter，the number of different berry shapes etc. were studied. The results showed that the particles of obovoid and narrow lipsoid fruits were larger，while the round grape fruits were smaller. The Vitis vinifera L. has more broad lipsoid and ovoid shapes，and there are more obovoid varieties of Vitis vinifera × V. labrusca. Table grapes are more elongated than wine，raisin and juice grapes. Black grapes are mainly round and nearly round，but white and red grapes have a rich berry shape. From the point of view of the breeding process，the berry shape of the grape is mainly round，and then became mainly round，nearly round and broad lipsoid，and more and more fruit forms appear one after another. Round，broad lipsoid and obovoid grape’s horizontal，longitudinal can fit well with fruit weights. There may be differences in the berry shape of the same grape variety，with broad lipsoid changes being prevalent.
