Juno

Faba bean

Variety Description

Variety used for comparison: 'DL Rico'

Summary: The flower of ‘Juno' is shorter than that of ‘DL Rico'. At the beginning of ripening, the pod attitude of ‘Juno' is semi-erect whereas it is erect on ‘DL Rico'. Excluding the beak, the pods of ‘Juno' are shorter and narrower than that of ‘DL Rico'.

Description:

PLANT: indeterminate growth type, flowers mid-season, matures mid to late season

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

FOLIAGE: medium green, maximum width of leaflets positioned towards the base

FLOWER: melanin spot absent on wing, anthocyanin colouration on standard absent

POD: semi-erect attitude, brown black colour at maturity
SEED: elliptic shape in median longitudinal section, grey beige colour of testa immediately after harvest, black pigmentation of hilum absent

Origin & Breeding History: ‘Juno' (experimental designation DL20.8703) originated by crossing the F1 of ‘Gloria' and ‘Devine' with ‘Espresso', as the female parent, and subsequently crossing the resulting F1 with ‘Babylon', as the male parent, at the breeding station in Hohenlieth, Germany. The initial and final crosses were conducted in 2009 and 2010, respectively. 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, flower colour 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 2020.

Tests & Trials: The comparative trials for ‘Juno' were conducted at the DL Seeds Research Station in Stanley, Manitoba during the 2022 and 2024 growing seasons. The trials were arranged in a RCB Design and consisted of 3 replications per variety. The 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 plot for each 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.
