Registration of ‘ND Dawn’ large yellow pea

Abstract

Abstract‘ND Dawn’ (Reg. no. CV‐30, PI 694866), a semi‐dwarf, semi‐leafless, large‐seeded yellow field pea (Pisum sativum L.) cultivar, was developed by the pulse crops breeding program at North Dakota State University and approved for release by the North Dakota Agricultural Experiment Station. ND Dawn, the first yellow field pea cultivar from the program, was developed by the bulk‐pedigree method. Based on 18 environments (location‐years) of yield trials across North Dakota, ND Dawn had similar seed yield (2,843 kg ha−1) with the commercial yellow pea cultivars ‘AC Agassiz’ (2,875 kg ha−1) and ‘DS Admiral’ (2,799 kg ha−1) but significantly greater than ‘CDC Golden’ (2,633 kg ha−1). ND Dawn was also tested across eight environments in Montana, where it had an average seed yield of 3,803 kg ha−1, which was significantly greater than ‘Delta’ (3,554 kg ha−1) but similar to DS Admiral (3,686 kg ha−1) or AC Agassiz (3,565 kg ha−1). ND Dawn matures in approximately 94 d. It is resistant to lodging, with a plant height index of 0.66. It has uniform round seed, with size larger than Agassiz, a medium‐seeded yellow pea cultivar. ND Dawn's protein content, 24%, is acceptable to get a premium price in the current market for high‐protein pea. ND Dawn and AC Agassiz exhibited similar responses to Fusarium root rot based on a field trial inoculated with multiple Fusarium species pathogenic to pea. In an irrigated field trial conducted under high Ascochyta blight pressure, ND Dawn yielded similarly to AC Agassiz and ‘CDC Striker’ despite having a higher leaf necrosis percentage. Other agronomic traits of ND Dawn are within market acceptable ranges.
