Variety Description

Variety used for comparison: 'CDC QG-1'

Summary: The plants of 'CDC QG-3' are later maturing than those of 'CDC QG-1'. The plants of 'CDC QG-3' are tolerant to imidazolinone herbicide whereas those of 'CDC QG-1' are not.


PLANT: late maturing

STEM: no anthocyanin colouration

LEAF: elliptic, rudimentary to prominent tendrils

FLOWER: flowers mid-season, medium to large, white standard with light violet stripes, white wings

POD: mainly two ovules per pod, no anthocyanin colouration, yellow at maturity, truncate to pointed apex
DRY SEED: narrow width, elliptic profile in longitudinal cross-section, green testa with no pattern, green cotyledon, dull brown hilum

Origin & Breeding History: 'CDC QG-3' (experimental designation IBC586) was developed from the cross 'CDC QG-1' /// 'CDC QG-1' // 'CDC QG-1' / 'CDC Maxim' carried out in 2009 at the Crop Development Centre at the University of Saskatchewan, Saskatoon, Saskatchewan. Selections were made in the F1 to F4 generations, where 28 sub-lines were used to establish the breeder seed. Throughout the generations, selections were based on yield, seed weight, seed size (including diameter and plumpness), seed coat colour, cotyledon colour, days to flowering, days to maturity, resistance to lodging, plant height, herbicide tolerance and disease resistance. 'CDC QG-3' was entered in and evaluated as IBC586 in the Pulse and Special Crops Cooperative Registration Tests in 2011 and 2012.

Tests & Trials: The tests and trials for 'CDC QG-3' were conducted at the Crop Development Centre of the University of Saskatchewan, Saskatoon, Saskatchewan during the summers of 2014 and 2015. 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 95 seeds per square metre. Measured characteristics were based on 20 measurements per variety per year. Mean differences were significant at the 5% confidence probability level based on a paired Student's t-test.
