Dosis

Faba bean

Variety Description

Variety used for comparison: 'Fabelle'

Summary: At the beginning of ripening, the plants of ‘Dosis' are shorter than the plants of 'Fabelle'.

Description:

PLANT: indeterminate growth type, flowers and matures mid-season

STEM: weak anthocyanin colouration, medium number of nodes up to and including the first flowering node

FOLIAGE: medium green, maximum width of leaflets positioned at middle

FLOWER: black melanin spot present on wing, small extent of colouration on standard

POD: erect attitude, brown black colour at maturity
SEED: beige colour of testa immediately after harvest, black pigmentation of hilum absent

Origin & Breeding History: ‘Dosis' (experimental designation RLS87103) originated by crossing the F1 of ‘Compass' and ‘Goldrush' with ‘Styria', as the female parent, and subsequently crossing the resulting F1 with ‘Fabelle', as the male parent, at the breeding station in Hohenlieth, Germany in 2011. Pedigreed breeding and selection methods were used. A single plant was selected in 2015 at the F5 generation based on straw stiffness, protein content, plant height, pod fertility, maturity, and vicine/convicine content. From 2017 and 2018, the F7 and F8 generations were tested in Germany and also evaluated for stability, purity, yield and resistance to Chocolate spot (Botrytis fabae) and Downy mildew (Peronospora viciae). Breeder seed was established after the F8 generation in 2018.

Tests & Trials: The comparative trials for ‘Dosis' were conducted at the DL Seeds Research Station in Morden, Manitoba during the 2022 and 2023 growing seasons. The trials were arranged in a RCB Design and consisted of 3 replications per variety. Plots consisted of six rows 4 metres in length with a row spacing of 17 cm. The planting density of 77 plants per square metre resulted in a total of 314 plants per variety. Measured characteristics were based on 100 measurements of each variety per year. Mean differences were significant at the 5% probability level based on a paired Student's t-test.
