Variety Description
Varieties used for comparison: 'CDC Maxim', 'CDC Redberry' and 'CDC Dazil'
Summary: 'CDC Impulse' has more pairs of leaflets per leaf than the reference varieties. 'CDC Impulse' flowers earlier than 'CDC Dazil'. The plants of 'CDC Impulse' are taller than those of the reference varieties. At maturity, the pods of 'CDC Impulse' are longer than those of the reference varieties. The seed of 'CDC Impulse' has one colour whereas that of 'CDC Dazil' has two. 'CDC Impulse' is tolerant to imidazolinone herbicide whereas 'CDC Redberry' is not.
Description:
PLANT: late maturing
STEM: weak to medium intensity of anthocyanin colouration
LEAF: elliptic, rudimentary to prominent tendrils
FLOWER: flowers mid-season, medium to large size, white standard with light violet stripes, white wings
POD: mainly two ovules per pod, no anthocyanin colouration, yellow at maturity, truncate apex
DRY SEED: narrow width, elliptic profile in longitudinal cross-section, one colour of testa, grey testa, orange cotyledon, dull brown hilum
Origin & Breeding History: 'CDC Impulse' (experimental designation IBC479) was developed from the cross 2262-14 /// 2262-14 // 2262-14 / '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 8 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 Impulse' was entered in and evaluated as IBC479 in the Pulse and Special Crops Cooperative Registration Tests in 2011 and 2012.
Tests & Trials: The tests and trials for 'CDC Impulse' 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.
