The purpose of this study was to evaluate fruit yield and berry quality parameters of ‘Yueguangwuhe’ grapevines grafted on eight rootstocks (SO4, 101-14M, 3309C, 188-08, 110R, 5C, 5BB and Beta, with own root as control) over three consecutive years. The results revealed that the greatest difference of fruit yield existed between vines on SO4 and 5BB which were both notably different from control. Vines on 101-14M produced the highest fruit berry weight, berry vertical diameter, berry horizontal diameter, total soluble solids concentration (TSS) and pressure resistance and the lowest values of titratable acidity (TA) and pulling resistance. The highest values of cluster weight and flesh firmness were obtained with SO4. Overall, SO4 and 101-14M performed better than all other rootstocks and control. These results could provide a valuable reference for cultivation of table grapes.
