Variety Description

Varieties used for comparison: 'CDC Viceroy', 'CDC Imvincible', 'CDC Impress' and 'CDC Imigreen'

Summary: The plant height of 'CDC Kermit' is shorter than that of 'CDC Viceroy', 'CDC Imvincible' and 'CDC Imigreen'. At maturity, the pods of 'CDC Kermit' are shorter than those of the reference varieties. 'CDC Kermit' is later maturing than 'CDC Viceroy'. The seed width of 'CDC Kermit' is very narrow whereas it is narrow for 'CDC Impress' and medium width for 'CDC Imigreen'. The seed testa of 'CDC Kermit' has two colours whereas 'CDC Impress' and 'CDC Imigreen' have one.

Description:

PLANT: late maturing

STEM: weak to medium intensity of anthocyanin colouration

LEAF: elliptic, rudimentary to prominent tendrils

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

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

Origin & Breeding History: 'CDC Kermit' (experimental designation 3592-13) was developed from the cross 1471T-A-10 / ('CDC Viceroy' / LC00600812P) carried out in 2005 at the Crop Development Centre at the University of Saskatchewan, Saskatoon, Saskatchewan. Selections were made in the F3 to F8 generations, where 42 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 and disease resistance. 'CDC Kermit' was entered in and evaluated as 3592-13 in the Pulse and Special Crops Cooperative Registration Tests in 2010 and 2011.

Tests & Trials: The tests and trials for 'CDC Kermit' 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.
