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.

Bibliographical note
Funding Information:We would like to thank all the agronomists, extension specialists, pulse growers, and people involved in conducting breeding nurseries and cultivar yield evaluation trials in North Dakota (Kandel et al., 2019) and Montana (Franck, Etamadi, & Chen, 2019). We would also like to thank all graduate students, interns, and summer workers for their assistance with disease screening, data management, and multilocation yield trials. ND Dawn was developed with support provided by Northern Pulse Growers Association through their checkoff system, ND Agricultural Experiment Station, USDA-NIFA (Hatch Project ND01513), USDA Agricultural Marketing Service, and the North Dakota Department of Agriculture through the Specialty Crop Block Grant Program (SCBGP). An original version of the manuscript was improved by suggestions and edits provided by Dr. Herman Kandel, North Dakota State University.
