Variety Description
Varieties used for comparison: 'Asuka' and 'Jari'
Summary: When 50% of the flowers are open, the terminal leaflet of 'Aurelina' is ovoid shaped whereas the shape of the terminal leaflet is elliptic for the reference varieties. When 95% of the pods are ripe, the pubescence on the middle third of the stem of 'Aurelina' is light tawny whereas it is tawny on the reference varieties. The plants of 'Aurelina' are taller than the plants of 'Asuka' and shorter than those of 'Jari'. The plants of 'Aurelina' mature earlier than the plants of 'Asuka' and later than those of 'Jari'. At maturity, the glaucosity on the seed of 'Aurelina' is of medium intensity whereas the glaucosity is weak on the seed of 'Asuka'. The seed weight of 'Aurelina' is less than than that of the reference varieties.

LEAF: ovoid shaped terminal leaflet, pointed ovate lateral leaflet
FLOWER: violet
POD: medium intensity of brown
SEED: small to medium sized, elongated to elongated flattened shape, yellow ground colour of testa, medium intensity of glaucosity
HILUM: yellow, yellow funicle
Origin & Breeding History: 'Aurelina' (experimental designation SZD5729) originated from a cross made in Reichersberg, Austria between 'SY Eliot' and 'Gallec' in 2011. The crossed material was derived using a single-pod descent technique until the F4 generation when a single plant was selected for maturity, protein content, yield, lodging resistance and resistance to pod shattering in 2012. Seed from this plant was harvested and maintained by pedigree selection until the F4:7 generation when 9 plants were selected to morphological uniformity in 2015 to establish the breeder seed.
Tests & Trials: The comparative trials for 'Aurelina' were conducted at C&M Seeds in Palmerston, Ontario, Canada in 2020 and 2021. The trials were planted in a RCB design with 4 replicates per variety. Each plot was 4 square metres and consisted of 4 rows space 0.4 metres apart with a seeding density of 70 seeds per square metre. Measurements were taken from 20 plants or parts of 20 plants of each variety per year. Mean differences were significant at the 5% probability level based on LSD values.
