STEM: anthocyanin colouration ranging between medium to strong and strong intensity
LEAF: elliptic, medium to long, medium width, medium number of pairs of leaflets
FLOWER: ranging between small to medium and medium sized, purple standard with weak violet stripes, violet stripes absent on wings
POD: mainly two ovules, yellow at maturity, medium length, truncate shaped apex
DRY SEED: narrow, broad elliptic profile in longitudinal cross section, grey testa with spotted grey patterning, dull brown hilum
USE: human consumption
Origin & Breeding History: 'CDC 7026' (experimental designation 7026-13Y) originated from the cross between 5030-6 and IBC1226-2 conducted at the Crop Development Centre, University of Saskatchewan, Saskatoon, Saskatchewan in 2014. A single plant selection was made from the F2 generation with further selections made at the F3 generation based on yield, seed weight, seed size which includes diameter and plumpness, seed coat colour, cotyledon colour, days to flower, days to maturity, lodging resistance, plant height and disease resistance. Seed from 50 F9 sub-lines was bulked to establish breeder seed in 2021.
Tests & Trials: The comparative trials for 'CDC 7026' were conducted at the Crop Development Centre of the University of Saskatchewan, Saskatoon, Saskatchewan in 2021 and 2022. The trials were conducted using a RCB 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 94 seeds per square metre. Measured characteristics were based on 20 measurements per variety per year except for seed weight which was based on a minimum of 8 measurements per variety per year. Mean differences were significant at the 5% probability level based on LSD values.
