Technical Abstract: The USDA has released the first southernpea cultivar that has a persistent green seed phenotype conditioned by both the green cotyledon gene (gc) and the green testa (gt) gene. The new cultivar, named DoubleGreen Delight, is a cream-type that produces dry seeds that have a richer and more uniform green color than dry seeds of either green cotyledon or green testa phenotype cultivars. DoubleGreen Delight seeds are much less susceptible to color loss due to blanching when harvest is delayed than are seeds of green cotyledon phenotype cultivars. DoubleGreen Delight originated as a bulk of an F9 (Bettergreen x Freezegreen) population grown in 1995. DoubleGreen Delight produces dry pods at Charleston, SC, in 65 to 71 days, usually about two to three days later than Bettergreen. The ovate to reniform shape of dry DoubleGreen Delight peas is similar to the shape of dry Bettergreen peas. DoubleGreen Delight peas have a smooth seed coat and are somewhat smaller than Bettergreen peas (weight per 100 dry peas: DoubleGreen Delight, 9.1 g; and Bettergreen, 9.7 g). The results of replicated trials indicate that the yield potential of DoubleGreen Delight is equal to that of Bettergreen. DoubleGreen Delight is recommended for use by the food freezing and dry-pack bean industries and home gardeners.
