Variety Description
Variety used for comparison: 'CDC Maxim'
Summary: At flowering, anthocyanin colouration is present on the peduncle of 'CDC Simmie' whereas the peduncle of 'CDC Maxim' has no anthocyanin colouration. The seed of 'CDC Simmie' is elliptic in longitudinal cross-section whereas it is broad elliptic for 'CDC Maxim'. The seed weight of 'CDC Simmie' is less than that of 'CDC Maxim'.
Description:
COTYLEDON: orange
PLANT: flowers early to mid-season, matures early to mid-season
STEM: medium intensity of anthocyanin colouration
LEAF: elliptic
PEDUNCLE: anthocyanin colouration present
FLOWER: medium size, white standard with weak to medium intensity violet stripes, violet stripes absent on wings
POD: mainly two ovules, yellow at maturity, truncate shaped apex
DRY SEED: narrow, elliptic in longitudinal cross-section, grey with no pattern on testa, dull brown hilum
USE: human consumption
Origin & Breeding History: 'CDC Simmie' (experimental designation IBC1235) originated from the cross between 'CDC Coral' and 'CDC Maxim' with 3 subsequent backcrosses to 'CDC Coral'. Crosses were conducted at the Crop Development Centre, University of Saskatchewan, Saskatoon, Saskatchewan from 2012 to 2013. During the F1 to F4 generations, selections were made based on yield, seed weight, seed size, seed coat colour, cotyledon colour, days to flower, days to maturity, lodging resistance, plant height and disease resistance. Seed from eight F4 sub-lines was bulked to establish breeder seed in 2017.
Tests & Trials: The comparative trials for 'CDC Simmie' were conducted at the Crop Development Centre, University of Saskatchewan, Saskatoon, Saskatchewan in 2019 and 2021. 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.
