Variety Description
Varieties used for comparison: 'Imposa', 'Nile' and 'Snowbird'
Summary: The leaflets of 'Athena' are longer than those of 'Snowbird'. The wing of 'Athena' has a melanin spot and the extent of anthocyanin colouration of the standard is large whereas 'Imposa' and 'Snowbird' have no melanin spot or anthocyanin colouration. The pod attitude of 'Athena' is semi-erect whereas that of the reference varieties is erect. The plants of 'Athena' are taller than those of 'Snowbird'. The pods of 'Athena' are longer than those of 'Snowbird'. The weight of 1000 dry seeds of 'Athena' is less than that of 'Imposa' and heavier than that of 'Snowbird'. The colour of the testa of the dry seed of 'Athena' is beige whereas it is grey beige for 'Imposa' and 'Snowbird'.
Description:
PLANT: indeterminate growth type, flowers and matures mid to late season
STEM: medium anthocyanin colouration, medium number of nodes up to and including the first flowering node
FOLIAGE: greyish green, maximum width of leaflets positioned at middle
FLOWER: black melanin spot present on wing, large extent of anthocyanin colouration on standard
POD: semi-erect attitude, brown black colour at maturity
SEED: elliptic shape of median longitudinal section, beige colour of testa immediately after harvest, black pigmentation of hilum absent
Origin & Breeding History: 'Athena' (experimental number LGFN14943) originated from a selection from the crossing of '91020' x 'Quatro' made in 2000. In 2002, a single plant was selected in the F2, followed by selfing and replicated yield trials and multiplication. The breeding was carried out at the applicant's breeding station in Lelystad, the Netherlands. Selection criteria for 'Athena' included yield, resistance to disease, resistance to lodging and plant maturity.
Tests & Trials: Tests and trials for 'Athena' were conducted at Barrhead, Alberta during 2015 and 2016 growing seasons. The trials consisted of 4 replicates per variety. Each plot was planted in 4 rows, spaced at 20cm and 4.5 metres in length. Measured characteristics were based on a minimum of 20 measurements per variety per year. Mean differences were significant at the 5% probability level based on a paired Student's t-test.
