Technical Abstract: The USDA has released a new, cream-type southernpea (Vigna unguiculata) cultivar that is well adapted for production throughout the southern United States. The new cultivar, named Tender Cream, is the product of a conventional recurrent backcross breeding procedure to transfer the dominant Rk gene for root-knot nematode resistance from Floricream into Carolina Cream. Tender Cream originated from a bulked F5 population derived from the sixth backcross. The Tender Cream phenotype is quite similar to those of Carolina Cream and Bettergreen. The new cultivar is resistant to the cowpea curculio, root-knot nematodes, southern bean mosaic virus, Cercospora leaf spot, southern blight, rust, and powdery mildew. Tender Cream outyielded the cream control in the 1992, 1993, and 1994 Regional Southernpea Cooperative Trials by 5.4%, 11.0%, and 18.8%, respectively. It outyielded its root-knot nematode susceptible Carolina Cream isoline by 22.3% in a replicated 1994 test conducted in a field infested with a natural population of the southern root-knot nematode. Canned samples of fresh Tender Cream peas scored well during three years of testing at the University of Arkansas. Tender Cream is recommended for use as a processing and home garden cultivar for spring, mid-season, and fall plantings.
