The performance of the table grape varieties Queen of the Vineyards, Muscat of Hamburg and Dabouki on eight different rootstocks, was studied in the arid Negev, on a loess soil under irrigation.The highest yields (nine years of bearing) from Queen of the Vineyards were recorded on 161-49, followed by 1202 and 99 R; from Muscat of Hamburg on ownroot plants, 41 B and 110 R; from Dabouki on 41 B, 110 R and 161-49. Maximum vigor in Queen of the Vineyards was obtained on 1202, followed by own-root plants and 1103; in Muscat of Hamburg, on 140 R and 1202; in Dabouki, 0n 110 R and 1202.Highest relative fruitfulness (ratio of total crop per total weight of prunings) 1Jf Queen of the Vineyards was found on 161-49, followed by 41 B and 216-3; of Muscat of Hamburg, on 110 Rand 41 B; of Dabouki, on 41 B and 216-3.No correlation was noted between the ranking of stionic combinations as to vigor and their ranking as yielders. There was a marked tendency toward decreased vigor with age, except on 140 with all three varieties, on 1103 and 1202 with Muscat, on 216-3 with Dabouki, and on 1103 with Queen of the Vineyards. A comparatively large overgrowth in the Dabouki variety with some rootstocks n.id not impair performance.Great variation was noted in the performance of different varieties of V. vinifera on their own roots; high relative yields were obtained with Muscat of Hamburg, and low yield with Queen of the Vineyards. Only small differences were found in quality, cluster weight and berry weight on different rootstocks
