Technical Abstract: The USDA has developed a new pinkeye-type southernpea cultivar named ‘GreenPack-DG’. ‘GreenPack-DG’ is the first pinkeye-type southernpea to be developed that has a persistent green seed phenotype conditioned by both the green cotyledon gene and the green testa (seed coat) gene. The new cultivar was developed from a cross between ‘Charleston Greenpack’ (green cotyledon phenotype) and the breeding line USVL 97-296 (green testa phenotype). ‘GreenPack-DG’ originated as a bulk of an F8 population grown in 2003. Except for longer pods, ‘GreenPack-DG’ is similar in appearance and maturity to ‘Charleston Greenpack’. Fresh peas are kidney shaped, slightly smaller than ‘Charleston Greenpack’ seeds, and have a pink eye. Dry ‘GreenPack-DG’ seeds have a richer and more uniform green seed color than dry seeds of ‘Charleston Greenpack’. The major attribute of the new cultivar is the persistence of the green color of unharvested dry peas long after optimal harvest. Results of three years of replicated field tests at Charleston, SC, indicate that ‘GreenPack-DG’ yields are comparable to ‘Charleston Greenpack’ yields. The new cultivar has excellent field resistance to blackeye cowpea mosaic virus and does not produce hard seeds. ‘GreenPack-DG’ is recommended for trial by the frozen food industry as a replacement for ‘Charleston Greenpack’. It should perform well in all areas where ‘Charleston Greenpack’ has been grown successfully.
