Title: Relative Performance of Ten 'Bath' Grape Clones
Authors: A.G. Reynolds, L.G. Denby and M.J. Bouthiller
Ten clones of 'Bath' (Vitis labruscana Bailey) were tested in British Columbia in a non-repli cated 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 pro duced fruit with low TA and high' pH. Since these clonal differences in fruit composition were not vigor- nor yield-related, it is con cluded that they are true phenotypic differ ences, and that clones 4, 7, and 9, are earlymaturing Bath clones.
