Variety Description
Variety used for comparison: 'DL Rico'
Summary: The plants of 'CDC 951' flower later than the plants of 'DL Rico'. The pod of 'CDC 951' is narrower than that of 'DL Rico'. The one hundred dry seed weight of 'CDC 951' is less than that of 'DL Rico'.
Description:
PLANT: indeterminate growth type, flowers mid-season, matures mid to late season
STEM: medium number of nodes up to and including the first flowering node
FOLIAGE: medium green, maximum width of leaflet positioned at middle
FLOWER: melanin spot absent on wing, no anthocyanin colouration on standard
POD: semi-erect attitude, brown black colour at maturity
SEED: irregular shape in median longitudinal section, grey beige colour of testa immediately after harvest, no black pigmentation of hilum
Origin & Breeding History: 'CDC 951' (experimental designation 951-1-11) originated from a cross between 'Navi' and 123-1 conducted in 2009 at the Crop Development Centre of the University of Saskatchewan in Saskatoon, Saskatchewan. Selections were made in the F1 to F4 generations and breeder seed was establish from the F9 generation. Selection criteria was based on vicine and convicine content, yield, seed weight, days to flowering, days to maturity, lodging resistance, plant height and disease resistance.
Tests & Trials: The comparative trials for 'CDC 951' were conducted in 2019 and 2021 at the Sutherland field site of the University of Saskatchewan in Saskatoon, Saskatchewan. The trials were arranged in a RCB design consisting of 3 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 43 seeds per square metre. Measured characteristics were based on 60 measurements of each variety per year except for seed weight which was based on 12 measurements per variety per year. Mean differences were significant at the 5% confidence probability level based on LSD values.
