Prediction of crude protein content in field peas using near infrared reflectance spectroscopy

A rapid, near-infrared spectroscopic method to predict the crude protein contents of 72 field pea lines grown in Saskatchewan, both whole seeds and ground samples, was established. Correlation coefficients between the laboratory and predicted values were 0.938 and 0.952 for whole seed and ground seed, respectively. Both methods developed are adequate to support our field pea breeding programme. Key words: Field pea, near-infrared reflectance spectroscopy, crude protein

Accumulation of Phosphorus-Containing Compounds in Developing Seeds of Low-Phytate Pea (Pisum sativum L.) Mutants

Low phytic acid (lpa) crops are low in phytic acid and high in inorganic phosphorus (Pi). In this study, two lpa pea genotypes, 1-150-81, 1-2347-144, and their progenitor CDC Bronco were grown in field trials for two years. The lpa genotypes were lower in IP6 and higher in Pi when compared to CDC Bronco. The total P concentration was similar in lpa genotypes and CDC Bronco throughout the seed development. The action of myo-inositol phosphate synthase (MIPS) (EC 5.5.1.4) is the first and rate-limiting step in the phytic acid biosynthesis pathway. Aiming at understanding the genetic basis of the lpa mutation in the pea, a 1530 bp open reading frame of MIPS was amplified from CDC Bronco and the lpa genotypes. Sequencing results showed no difference in coding sequence in MIPS between CDC Bronco and lpa genotypes. Transcription levels of MIPS were relatively lower at 49 days after flowering (DAF) than at 14 DAF for CDC Bronco and lpa lines. This study elucidated the rate and accumulation of phosphorus compounds in lpa genotypes. The data also demonstrated that mutation in MIPS was not responsible for the lpa trait in these pea lines.

CDC Forest green field pea

Abstract: CDC Forest, a green cotyledon field pea (Pisum sativum L.) cultivar, was released in 2017 by the Crop Development Centre, University of Saskatchewan for distribution to select seed growers through the Variety Release Committee of the Saskatchewan Pulse Growers. CDC Forest has good lodging resistance, medium-sized round seeds, and good yielding ability. CDC Forest is adapted to the field pea growing regions of western Canada.

CDC Canary yellow field pea

Abstract: CDC Canary, a yellow cotyledon field pea (Pisum sativum L.) cultivar, was released in 2017 by the Crop Development Centre, University of Saskatchewan for distribution to select seed growers through the Variety Release Committee of the Saskatchewan Pulse Growers. CDC Canary has good lodging resistance, medium-sized round seeds, early maturity, and good yielding ability. CDC Canary is adapted to the field pea growing regions of western Canada.

CDC Athabasca yellow field pea

Abstract: CDC Athabasca, a yellow cotyledon field pea (Pisum sativum L.) cultivar, was released in 2016 by the Crop Development Centre, University of Saskatchewan for distribution to select seed growers through the Variety Release Committee of the Saskatchewan Pulse Growers. CDC Athabasca has good lodging resistance, large-sized round seeds, and good yielding ability. CDC Athabasca is adapted to the field pea growing regions of western Canada.
