Summer Black,5BB,3309M,and Huajia No.8 grapes were used as rootstocks and grafted with Shine Muscat grapes respectively,the compatibility,fruit maturity,fruit and cluster characteristics of four rootstock-scion combinations were compared and analyzed.The results showed that under the conditions of inflorescence pruning,single layer fruit grain whole panicle,and control of yield,the soluble solid content of the four rootstock-scion combinations of Shine Muscat grapes is above 17%,meeting the standards for high-quality commercial fruits.The yield per 666.7 m2 reached more than 1 200 kg in the second year of planting,and more than 2 000 kg in the third and fourth years,reaching the expected yield target.The compatibility and early maturing advantage between the rootstock-scion combination of Summer Black and Shine Muscat grapes were significant.
