Ten clones of ‘Bath’ ( Vitis labruscanaBailey) were tested in British Columbia in a non-replicated observational trial between 1976 and 1983 and in a replicated trial between 1984 and 1988. There were no consistent differences in vigor or yield of the ten clones. Clone 7 fruit generally maintained highest °Brix and pH as well as lowest titratable acidity (TA) throughout the course of both trials. Clones 4 and 9 also produced fruit with low TA and high pH. Since these clonal differences in fruit composition were not vigor- nor yield-related, it is concluded that they are true phenotypic differences, and that clones 4, 7, and 9, are early-maturing Bath clones.
