AB Seven Cabernet Sauvignon clones from Foundation Plant Materials Service (FPMS), University of California, were evaluated over a three-year period in the Lodi-Woodbridge District of the northern San Joaquin Valley, California. FPMS 2, 4, 5, 6, 8, 10, and 21 were all certified virus-tested. FPMS 6 had the greatest pruning weight (2.8 kg vine-1) while FPMS 8 and 10 had the least (2.0 and 1.9 kg vine-1, respectively). FPMS 6 had the lowest average yield (7.0 kg vine-1) while FPMS 21 had the highest average yield (9.7 kg vine-l). Vine yield was highly correlated (r2 = 0.96) with cluster weight while cluster numbers did not differ. Contributions to cluster weight were made by both berries per cluster and berry weight. Despite yield differences of 2.7 kg vine-1, average °Brix varied by only 1.2°. Titratable acidity and pH differences were negligible.
