Verification through Pollen Incompatibility Studies of Pedigrees of Sweet Cherry Cultivars from Vineland

Abstract
Pedigrees of Wit', `Venus', `Viscount', `Vogue', and `Viva' sweet cherry cultivars (Prunus avium L.) were confirmed with pollen-incompatibility studies. `Hedelfingen', the maternal parent of the last four cultivars, was assigned previously to Incompatibility Group VII (S4S5); however, it was shown that Vineland `Hedelfingen' belongs to Group `O' (Universal Donors) rather than VII. Thus, the parentage of the above cultivars, with the exception of `Vic', is correct as reported when these cultivars were named. `Vie' pedigree is incorrect and it belongs to Group `O' rather than the previously assigned XIII. `Valera' also belongs to Group `O' and the existence of Group XIV (S1S5), with `Valera' as its only representative cultivar, could not be confirmed.
