Abstract: In order to evaluate the effects of rootstock grafting on the growth and fruit quality of Xinyu grape in the humid and hot regions of South China, the experimental materials were Xinyu grapes grafted with four different rootstocks Gloire, Summer Black, Kangzhen No.1, Kangzhen No.6. The related indexes of different rootstock-scion combinations were investigated, including phenological period, growth and fruiting habits, fruit economic characteristics, nutrient composition, etc. The differences of rootstock-scion combinations were analyzed, and the fruit quality of grape rootstock-scion combinations was evaluated comprehensively by principal component analysis. The results showed that four rootstock-scion combinations could increase the germination rate and fruiting branch rate of Xinyu, and the total phenol and sugar content of Gloire and self-rooted seedlings were significantly higher than those of Summer Black, Kangzhen No.1, Kangzhen No.6. The average grain weight of Gloire and Kangzhen No.1 were significantly higher than that of Summer Black and self-rooted seedlings. Principal component analysis showed that among the four rootstocks, Gloire was the best one for Xinyu grape.
