Registration of ‘ND Victory’ green field pea

Abstract

Abstract‘ND Victory’ (Reg. no. CV‐31, PI 701908) is the first semi‐leafless, green cotyledon field pea cultivar (Pisum sativum L.) developed by the North Dakota State University Pulse Crops Breeding Program and approved for release by the North Dakota Agricultural Experiment Station. It has white flowers, opaque seed coat, and smooth, round seed. It is semi‐dwarf, with lodging score of 3.3/9 and canopy height of 57 cm. Based on 30 environments (location‐year) of replicated yield trials in North Dakota, seed yield of ND Victory (2847 kg ha−1) was similar to commercial cultivar ‘CDC Striker’ (2819 kg ha−1) but significantly greater than ‘Cruiser’ (2653 kg ha−1) and ‘Aragorn’ (2639 kg ha−1) by 7.3 and 7.9%, respectively. ND Victory was also tested across 14 environments in Montana, where it had an average seed yield of 3264 kg ha−1, which was similar to ‘Hampton’ (3355 kg ha−1) but significantly greater than Aragorn (3110 kg ha−1) by 4.9%. ND Victory matures in approximately 90 days. ND Victory is a high protein cultivar, with protein content of 25.2%, exceeding the premium protein threshold of 24%. ND Victory (20%) is resistant to powdery mildew and performed similarly with resistant check ‘Spider’ (15%) and had significantly lower disease severity than ‘Salamanca’ (97%, susceptible check) and CDC Striker (82%). In irrigated field trials conducted under high Ascochyta blight pressure, ND Victory (5%) had lower disease severity than ‘AC Agassiz’ (10%) and CDC Striker (14%). ND Victory and CDC Striker exhibited similar response but significantly lower severity than AC Agassiz to Fusarium root rot inoculated with multiple Fusarium species pathogenic to pea.
