Previous lists of Cucurbita genes were published in CGC Rpt. 15:102-109 (1992) and in CGC Rpt. 19: 91-92 (1996). Before publishing a proposed new gene symbol for a Cucurbita gene, researchers are urged to consult this gene list and those in CGC 15 and 19 in order to avoid using a symbol already assigned to another gene.
The following list of new Cucurbita genes also includes a correction for the erroneous symbol for the Ds gene that was given in CGC Rpt. 19: 91-92 (1996).
Gene | Character | Species | Reference |
Dx | Dark stem only, fruit color not affected | pepo | 4 |
| De | determinate plant habit; stem lacking tendrils and terminating with female flowers | moschata | 2 |
| mo-1 | mature orange-1; complementary gene for loss of green fruit color prior to maturity | pepo | 5 |
| mo-2 | mature orange-2; complementary gene for loss of green fruit color prior to maturity | pepo | 5 |
| Slc* | Squash leaf curl virus resistance | pepo | 3 |
| uml | umbrella-like; leaves shaped like partially opened umbrella | maxima x pepo | 6 |
| wc | white corolla; petals white, tending to curl, less dentate than normal | maxima | 1 |
| wyc | white-yellow corolla; dentate, white-yellow petals | maxima | 1 |
