Cucumbers and other cucurbit crops are subject to severe losses due to an array of potyviruses, including zucchini yellow mosaic virus (ZYMV), watermelon mosaic virus (WMV), and the watermelon strain of papaya ringspot virus (PRSV-W). Sources of resistance to these viruses have been identified within the cucumber germplasm, including resistance to ZYMV, WMV, and PRSV in `TMG-l'; resistance to PRSV in `Surinam'; and to ZYMV in `Dina'. In this study, we sought to determine the allelic relationships between resistance to PRSV in `Surinam' and `TMG' and resistance to ZYMV in `Dina' and `TMG'. Segregation ratios among F 1 , F 2 , and backcross progeny of `Surinam' and `TMG' indicated that the alleles are at the same locus. Similarly, progeny analysis indicates that the alleles for ZYMV resistance in `Dina' and `TMG' are at the same locus. In each case, however, the alleles appear to differ from one another with respect to dominance relationships, symptom expression, and/or response to different viral strains. We are further characterizing these differences by screening progeny of crosses to a common susceptible parent.
