‘GreenPack-DG’ is a new southernpea [Vigna unguiculata (L.) Walp.] released 9 Jan. 2006 by the Agricultural Research Service of the U.S. Department of Agriculture. ‘GreenPack-DG’ is the first pinkeye-type southernpea to be released that has a persistent green seed phenotype conditioned by both the green cotyledon gene and the green testa (seedcoat) gene. Dry ‘GreenPack-DG’ seeds have a richer and more uniform green seed color than dry seeds of green cotyledon phenotype cultivars, and the seeds are much less susceptible to color loss due to blanching when harvesting is delayed. ‘GreenPack-DG’ was developed as a replacement for ‘Charleston Greenpack’, a pinkeye-type cultivar with a green cotyledon phenotype that is used extensively by the frozen-food industry.
