The growth of germ‐tubes of Botrytis cinerea at 24°C on leaf discs of six cabbage cultivars taken from heads prior to storage, was directly related to the proportion of whole heads developing rots caused by Botrytis during storage for 6 months at 1–2°C. Dipping heads in iprodione before cold storage substantially reduced losses, particularly in the most susceptible cultivar (Decema Extra). Both leaf disc assays of germ‐tube growth and studies of whole heads in store indicated significant and similarly ranked differences in cultivar susceptibility.
