'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. Core Ideas: ND Victory is the first semi‐dwarf, semi‐leafless green field pea released from the NDSU Pulse Breeding Program.ND Victory has high yield potential in North Dakota and Montana.ND Victory's protein content is 1.2% above acceptable premium price in the high‐protein pea market.ND Victory is resistant to powdery mildew and has low severity due to Ascochyta blight and Fusarium root rot.The northern Great Plains of North Dakota and Montana continue to be the primary growing region for field pea in the United States.

'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. [ABSTRACT FROM AUTHOR]

Abstract: Gluten strength is an important characteristic, determining the end product quality of durum wheat semolina. To identify the genetic basis of gluten strength in North Dakota durum cultivars, a doubled haploid population was developed from the cross of a weak gluten cultivar ‘Rugby’ and a strong gluten cultivar ‘Maier’. A framework linkage map consisting of 228 markers was constructed and used with phenotypic data on gluten strength (measured by sedimentation volume) to conduct single- and two-locus QTL analyses. Only one consistent QTL (QGs.ndsu-1B) contributing up to 90% of the phenotypic or 93% of the genotypic variation was detected on 1BS. No QTL × QTL or QTL × environment interactions were observed. The QGs.ndsu-1B was flanked by two DArT markers which were converted to STS markers and used along with SSR and EST-SSRs to develop a map of 1BS. QTL analysis delineated QGs.ndsu-1B in a 7.3 cM region flanked by an STS marker (STS-wPt2395) and a SSR marker (wmc85). The adapted background of this material and availability of PCR-based markers closely associated with this locus represent invaluable resources for marker-assisted introgression of gluten strength into other durum wheat varieties. A single QTL segregating in this population also makes it an ideal target for map-based cloning. [Copyright &y& Elsevier]
