The USDA has released a new, pinkeye-type southernpea cultivar that is homozygous for the gc gene conditioning the green cotyledon trait. The new cultivar, `Charleston Greenpack', can be harvested at the near-dry stage of pod maturity without loss of the pea's fresh green color. `Charleston Greenpack' originated as a bulk of an F8 [`Kiawah' × (`Kiawah' × `Bettergreen')] population grown in 1994. Except for the green seed color, a tendency for a slightly greener foliage, and a slightly smaller pea size, the phenotype of `Charleston Greenpack' is quite similar to those of `Coronet' and `Pinkeye Purple Hull-BVR'. The results of replicated field tests indicate that `Charleston Greenpack' yields are comparable to those of `Coronet' and `Pinkeye Purple Hull-BVR'. Results of raw product evaluations conducted at a commercial freezing facility indicate that `Charleston Greenpack' produces an excellent processed product. `Charleston Greenpack' has excellent field resistance to blackeye cowpea mosaic virus, the major pathogen of southernpea in the United States.
