Variety Description
Varieties used for comparison: 'Aya' and 'Genesis'
Summary: When 50% of the flowers are open, the branch attitude of 'Wilma' is erect to semi-erect whereas it is semi-erect for the reference varieties. From 50% flowering to when 95% of the pods are ripe, on the middle third of the main stem, the pubescence of 'Wilma' is light tawny whereas it is grey for the reference varieties. When 95% of the pods are ripe, the intensity of brown colour of the pod of 'Wilma' is light whereas it is medium for the reference varieties. At maturity, the one hundred seed weight for 'Wilma' is greater than that of 'Genesis'. The plants of 'Wilma' mature later than the plants of 'Aya'.

Origin & Breeding History: 'Wilma' (experimental designation PR140995Z-14) originated from a cross between the varieties 'OAC Calypso' and 'VIR 1238' conducted in 2014 in Saint-Césaire, Québec using the modified individual pedigree selection method of plant breeding. From 2015 to 2016, four generations were advanced between Rojas, Argentina and Saint-Césaire, Québec by single plant selection, line selection and yield testing. Selection criteria included yield, maturity, lodging resistance and disease resistance. 'Wilma' was selected at the F5 generation in 2016. Breeder seed was produced from F10 lines in 2021.
Tests & Trials: The comparative trials for 'Wilma' conducted in Saint-Césaire, Québec during the 2023 and 2024 growing seasons. Trials were planted in a RCB design and consisted of 2 replicates for each variety. Plots consisted of 2 rows, 5 metres in length and a row spacing of 76 cm. The trial consisted of 350 plants per variety. Measurements were taken from 20 plants or parts of 20 plants of each variety per year except for the seed weight with 10 measurements per variety per year. Mean differences were significant at the 5% probability level based on a Student's t-test.
