Technical Abstract: Efforts to incorporate genes conditioning a persistent green seed phenotype into Zipper Cream and White Acre type backgrounds were completed with the official release of the new southernpea cultivars ZipperCream-CG and WhiteAcre-DG on 29 January 2008. ZipperCream-CG is a high yielding, large-seeded, cream-type breeding line with a persistent green phenotype conditioned by the green cotyledon gene; it was developed using a backcross/pedigree breeding procedure that utilized Zipper Cream, Bettergreen, and Freezegreen as parental lines. The plant, pod, seed, and maturity characteristics of ZipperCream-CG are quite similar to those of Zipper Cream. WhiteAcre-DG is a high yielding, small-seeded, cream type breeding line with a persistent green seed phenotype conditioned by both the green cotyledon gene and green testa gene; it was developed using a relatively complex pedigree breeding procedure that utilized White Acre, Mississippi Silver, Freezegreen, and Bettergreen as parental lines. White Acre was utilized as a parent in four of the crosses. WhiteAcre-DG plants are similar in appearance to White Acre plants, but mature to the dry-pod harvest stage 4 to 9 days earlier. WhiteAcre-DG peas have an ovate to globose shape, similar to White Acre peas. The major attribute of both ZipperCream-CG and WhiteAcre-DG is their persistent green seed phenotype; both of these breeding lines can be harvested at the dry stage of maturity without loss of the pea’s fresh green color.
