Abstract:
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.
