Variety Description

Varieties used for comparison: 'Dares', 'Etna' and 'OAC Wallace'

Summary: When 50% of the pods are ripe, the plants of 'Ajico' are shorter than those of 'Dares'. 'Ajico' has a rounded ovate lateral leaflet whereas 'Dares' and 'OAC Wallace' have a pointed ovate lateral leaflet. 'Ajico' has medium sized lateral leaflet whereas 'Etna' and 'OAC Wallace' have small lateral leaflet. When 95% of the pods are ripe, the intensity of the brown colour on the pod is light for 'Ajico' whereas it is of medium intensity for 'Dares' and medium to dark for 'Etna'. The seed of 'Ajico' is large whereas the seed of 'OAC Wallace' is medium sized. The colour of the hilum of 'Ajico' is imperfect yellow whereas it is dark brown in 'OAC Wallace'. The hilum is lacking the abscission layer on 'Ajico' whereas 'Etna' retains the abscission layer on the hilum. 'Ajico' matures later than 'Etna'.

Description:

HYPOCOTYL: strong intensity of anthocyanin colouration

PLANT: oilseed type, indeterminate growth type, semi-erect to horizontal growth habit, begins flowering mid-season and matures medium-late to late in season

STEM: tawny pubescence on middle third

LEAF: dark green, medium blistering
LATERAL LEAFLET: rounded ovate, medium size

FLOWER: violet

POD: light brown
SEED: large, spherical flattened shape, yellow ground colour of testa
HILUM: imperfect yellow
FUNICLE: same colour as the testa

Origin & Breeding History: 'Ajico' (experimental designations CFS13.5.01 and C4M15027) is the result of a cross between propriety selections conducted in 2005 by La Coop fédérée, Saint-Hyacinthe, Quebec, Canada. The modified single seed descent method was used to develop the variety. From 2005 to 2007, F1-F4 generations were grown in Santa Isabel, Puerto Rico, and advanced by modified single-seed descent. In 2007, filial generation F5, grown in Saint-Hyacinthe, was selected based on visual assessment of yield and seed size. In 2008, progeny rows from 2007 selection were evaluated and the line that became 'Ajico' was selected based on maturity and on a visual assessment of lodging resistance and yield potential. From 2009 to 2018, 'Ajico' was tested in replicated private trials in multiple locations. It was also tested as CFS13.5.01 or 'Ajico' in the Réseau Grandes Cultures du Québec and Ontario Oil and Protein Seed Crop Committee trials from 2013 to 2018.

Tests & Trials: The comparative trials for 'Ajico' were conducted at the crop production research farm of La Coop fédérée in Saint-Hyacinthe, Quebec. The trials were planted in a RCB design with 3 replicates per variety during the 2017 growing season and 4 replicates per variety during the 2018 growing season. Each 7.5 square metre plot consisted of 4 rows, each 5 metres long with a row spacing of 0.38 metres. The seeding density was such that it resulted in a total of over 30 plants per variety per square metre. For each variety, the plant height was based on 30 measurements. Mean differences were significant at the 5% probability level based on LSD values.
