Variety Description
Varieties used for comparison: 'CDC Maxim', 'CDC Redberry' and 'CDC Impala'
Summary: The leaflet of 'CDC Nimble' is shorter than that of 'CDC Impala'. The plants of 'CDC Nimble' mature earlier than those of 'CDC Maxim'. The seed weight of 'CDC Nimble' is less than that of 'CDC Redberry' and greater than that of 'CDC Impala'. The plants of 'CDC Nimble' are tolerant to imidazolinone herbicide whereas the plants of 'CDC Redberry' are not tolerant.
Description:
COTYLEDON: orange
PLANT: matures mid-season
STEM: weak intensity of anthocyanin colouration
LEAF: elliptic
FLOWER: flowers early to mid-season, medium size, standard is white with violet stripes, violet stripes absent on wings
POD: mainly two ovules, yellow at maturity, truncate shaped apex
DRY SEED: narrow, elliptic to broad elliptic in longitudinal cross-section, grey testa with no patterning, dull brown hilum
USE: human consumption
Origin & Breeding History: 'CDC Nimble' (experimental designation IBC 975) originated from the cross between 'CDC Impala' and 'CDC Redmoon' with 3 additional backcrosses to 'CDC Redmoon'. The final cross was conducted at the Crop Development Centre, University of Saskatchewan, Saskatoon, Saskatchewan in 2012. Selections were made during the F1 to F4 generations based on yield, seed weight, seed size, days to flower, days to maturity, lodging resistance, plant height and disease resistance. Twenty-seven sub-lines selected from the F4 generation were used to establish breeder seed.
Tests & Trials: The comparative trials for 'CDC Nimble' were conducted at the Crop Development Centre of the University of Saskatchewan, Saskatoon, Saskatchewan during the 2016 and 2019 growing seasons. 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 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 a Student's t-test. Data to support Imidazolinone tolerances was provided by BASF Inc. in Saskatoon Saskatchewan.
