Abstract

PS03101269 (Reg. No. GP-107, PI 663943) pea (Pisum sativum L.) germplasm was developed by the USDA-ARS in cooperation with the Washington Agricultural Research Center, Pullman, WA and North Dakota State University, Fargo, ND. PS03101269 is an autumn-sown pea with green cotyledons and a clear seed coat. It was bred specifically for high-value, food-quality seed characteristics and adaptation to harsh winter conditions. It was jointly released by the USDA-ARS and North Dakota State University as a breeding line in 2011. PS03101269 was developed using a modified bulk pedigree system. It was identified as an F6 selection from the cross CAH-61/‘Granger’ (cross number X98P096). PS03101269 was evaluated in autumn-sown yield trials for a total of 12 location- years in Washington. Across all locations, the grain yield of PS03101269 averaged 2354 kg ha−1, and the plants reached maturity in approximately 250 d. PS03101269 is semileafless and has long internodes and white, unpigmented flowers. The average 100-seed weight is 15.4 g. Due to its relatively small seed size, it is anticipated that the primary use of PS03101269 will be by breeders in the development of autumn-sown food-quality pea cultivars. Secondarily, it is expected that this germplasm will be used as a forage or cover crop variety.
