Description:
Originated from a cross of CR1 x F1(FMR#3 x SC#6). CR1 is an accession of what was at the time classified as C. melo ssp. agrestis, but currently may be regarded as C. melo Group Agrestis (Pitrat, 2016); it has a fractal growth habit (Staub et al., 2011). Breeding line FMR#3 was an F3 selection from a cross of Galia x Qalya (Paris et al., 1989) and may be characterized as C. melo Group Inodorus. Breeding line SC#6 was an S5 from a complex cross of Eastern U.S. market-type melons (C. melo Group Cantalupensis Sub-group American Eastern) selected by Perry E. Nugent (retired, USDA-ARS, U.S. Vegetable Laboratory, Charleston, SC) for germinability at low temperature. A monoecious, early-flowering (in Wisconsin) plant was chosen from this three-way cross and self-pollinated four generations with concomitant selection for branching, earliness, and monoecy to produce an S4 line designated USDA 846-1. The deposited seed is a bulk of nine sib-pollinated plants from the original material.
Fruit of this line are slightly netted, non-ribbed, free of vein tracts (Davis, 1970), and typically oval.
