Origin & Breeding History: '1217-2' originated from the cross ('757-3' / 'CDC 1812-5') / ('757-1' / 'Genki') conducted in 2009 at the Crop Development Centre at the University of Saskatchewan, Saskatoon, Saskatchewan. '1217-2' was developed from a single plant selection from the F2 population. '1217-2' was evaluated in the Crop Developement Centre marrowfat pea advanced trials in 2014 and in the Crop Developement Centre marrowfat pea elite trials in 2015 and 2016. It was selected for its yield, days to maturity, days to flowering, vine length, resistance to lodging, seed weight, seed size and disease resistance.
Tests & Trials: The comparative tests and trials for '1217-2' were conducted at the Sutherland Field Site of the Crop Development Centre of the University of Saskatchewan, Saskatoon, Saskatchewan during the 2016 and 2017 growing seasons. The trials were established using a complete randomized block design consisting of 2 replications per variety. Each replicate consisted of 3 rows spaced 30 cm apart, with a row length of 3.66 metres and a planting density of 65 seeds per square metre. The measured characteristics were based on 20 measurements per variety per year and there were 8 measurements made for 100 seed weight. The mean differences were significant at the 5% confidence probability level based on a paired Student's t-test.
