18 Availability Commercial development by the University of Guelph and the Ontario Ministry of Agriculture. V.1', V.2 and V.3' have been licensed More information is required to determine the suitability of commercializing V.5', V.6', and V.7'. V.2 has been commercially released but has been difficult to propagate in the nursery, therefore it may have limited availability. V.4 will not be commercialized.
