Variety Description
Variety used for comparison: 'CDC KR-2'
Summary: The plants of 'CDC Monarch' flower earlier than the plants of 'CDC KR-2'. At flowering, anthocyanin colouration is present on the peduncle of 'CDC Monarch' whereas anthocyanin colouration is absent on the peduncle of 'CDC KR-2'. At maturity, the plants of 'CDC Monarch' are taller than those of 'CDC KR-2'.
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 sized, 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: medium width, broad elliptic in longitudinal cross-section, grey with no pattern on testa, dull brown hilum
USE: human consumption
Origin & Breeding History: 'CDC Monarch' (experimental designation IBC1306) originated from the cross between 4475-11 and 'CDC Impulse' with 3 subsequent backcrosses to 4475-11. Crosses were conducted at the Crop Development Centre, University of Saskatchewan, Saskatoon, Saskatchewan from 2012 to 2014. 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 thirty-five F4 sub-lines were bulked to establish breeder seed in 2020.
Tests & Trials: The comparative trials for 'CDC Monarch' were conducted at the Crop Development Centre, University of Saskatchewan, Saskatoon, Saskatchewan in 2020 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.
