The bold terms are used in the remainder of the text, tables, and figures for simplicity. † The resistance loci (alleles) present in each vine are listed here, based on AmpSeq analysis of previously published markers [1720]. DVIT2732-6 lacks REN4 but has moderate resistance from an unknown pollen donor. The full-sibling progeny (452033, 452036, and 452051) of the biparental cross “Horizon” × V. rupestris B38 likely carries the REN3/REN9 locus conferring moderate resistance.
