Abstract: Abstract: This research aims to take advantage of the merits of‘Cabernet Franc’,‘Syrah’and‘Pinot Noir’ clonal lines, and provide a basis for breeding new wine grape varieties with high polyphenol content. Using three clonal lines of‘Cabernet Franc’, two clonal lines of‘Syrah’and‘Pinot Noir’as materials, the cluster weight, average berry mass and soluble solid content, titratable acid content, the ratio of peel to pulp, and juice yield were measured, total anthocyanins content in pericarp, total polyphenol, tannin, total flavonoid and proanthocyanidin in pericarp, flesh and seed were evaluated using colorimetric method. There were differences in the fruit quality of‘Cabernet Franc’,‘Syrah’and‘Pinot Noir’, and also differences among various clonal lines. The content of phenolics in peel and pulp of‘Pinot Noir 115’was relatively high, but they were much higher in the seeds of‘Pinot Noir 667’.‘Syrah 100’had relatively high content of total anthocyanins, proanthocyanidins in the peel, tannins in the pulp and total flavonoid in the seeds.‘Cabernet Franc 327’had the highest content of total anthocyanins, total phenols and tannins in the pulp, and proanthocyanidin content in the seeds, while‘Cabernet Franc c214’had the highest content of total phenols, tannins, and total flavonoids in the seeds, however‘Cabernet Franc 409’had the highest content of total flavonoids, proanthocyanidins in the peel and total flavonoids in the pulp.
