Abstract: In order to provide reference for the selection of suitable scion-rootstock combinations in the production of wine grape in Ningxia.Chardonnay and Merlot were grafted with three rootstocks respectively to study the effects of rootstocks on the growth, fruit quality and yield of two kinds of grapes.The results showed that 5BB, 1103P and 110R promoted the growth of Chardonnay in different degrees, among which 1103P increased the trunk diameter, leaf area and SPAD value significantly, and the effect of increasing growth was the most obvious. 5BB significantly increased the reducing sugar and titratable acid content of Chardonnay fruit, while 1103P decreased the accumulation of reducing sugar and increased the content of titratable acid, and 110R had no significant effect on the sugar and acid content. 1103P and 110R significantly reduced the total phenol content of Chardonnay, while 5BB and 1103P increased the anthocyanin content significantly. There was no significant difference in yield per plant between the grafted and self-rooted Chardonnay. The growth of Merlot grafted onto 140R, 5BB and SO4 was slowed down evidently, among which 140R significantly reduced the trunk diameter, new shoot length and diameter, leaf area and SPAD value, and the effect of weakening growth was the most obvious. SO4 significantly decreased the reducing sugar content and increased titratable acid content of Merlot fruit, while 5BB had no significant effect on the reducing sugar content, but significantly increased the titratable acid content, and 140R had no significant effect on sugar and acid content. Three rootstocks improved the tannin and anthocyanin content of Merlot fruit, among which 140R showed a significant raise in tannin content, and the anthocyanin content of SO4 and 140R grafted was obviously higher than that of self-rooted. The rootstock 5BB significantly increased the yield per plant of Merlot.Among the three rootstocks, 5BB was the best one for Chardonnay;but for Merlot, the self-rooted seedling was the best, and the comprehensive performance of 5BB was better than the other two rootstocks in terms of stable growth, quality and yield.
