Interpretive Summary: In a plant breeding program, knowing the parents helps breeders in selection of parents for future use. However, plant breeders’ records occasionally contain errors. In this project, DNA markers were used to determine parents for grape varieties from the Cornell breeding program and a few key varieties used as parents. As expected, most (20 of 24) reported parents were correct. Unlike published reports, ‘Suffolk Red’ and ‘Glenora’ were shown to have ‘Black Kishmish’ and not ‘Black Monukka’ as a parent. The advanced selection NY 63.0970.07 is a hybrid of ‘Pinot noir’, not ‘Gamay’, x ‘Chancellor’. ‘Vignoles’ (Ravat 51) is not descended from the reported parentage of Seibel 6905 x ‘Pinot noir’.

Technical Abstract: In a plant breeding program, an accurate understanding of pedigrees provides useful guidance for future hybridizations. However, plant breeders’ records occasionally contain errors. In this project, SSR markers were used to confirm or correct pedigrees for grape varieties from the Cornell breeding program and a few key varieties used as parents. As expected, most (20 of 24) reported pedigrees were confirmed. Recognizing a heritable null allele from ‘Ontario’, at VVMD25, was necessary for parent progeny analysis of several varieties. ‘Suffolk Red’ and ‘Glenora’ were shown to be progeny of ‘Black Kishmish’ and not ‘Black Monukka’. The advanced selection NY 63.0970.07 is a hybrid of ‘Pinot noir’, not ‘Gamay’, x ‘Chancellor’. ‘Vignoles’ (Ravat 51) is not descended from the reported parentage of Seibel 6905 x ‘Pinot noir’.
