Eternal

Bean

Variety Description

Varieties used for comparison: 'Windbreaker' and 'ND Palomino'

Summary: At full flowering, the upper side of the leaf of ‘Eternal' is dark green while that of ‘ND Palomino' is medium green. Stringiness of the ventral suture is absent on the pod of ‘Eternal' while it is present on the pods of the reference varieties. At fresh market maturity, the pod of 'Eternal' is longer than those of the reference varieties. The beak on the pod of 'Eternal' is longer than those of the reference varieties. The seed weight of 'Eternal' is less than those of the reference varieties. The seed of ‘Eternal' is elliptic in longitudinal section while those of the reference varieties are circular to elliptic in longitudinal section. The seed of ‘Eternal' is narrow in cross section while those of the reference varieties are of a medium width in cross section. The plants of ‘Eternal' flower later than those of ‘ND Palomino'.

Origin & Breeding History: 'Eternal' (experimental designation P16HR025) originated from a controlled cross conducted in 2013 at the University of Guelph in Guelph, Ontario between the lines PT9-6 and W12HR1410. The variety was advanced with single F5 plants selected in 2015 based on high pod number, plant architecture and maturity. An F6 progeny row was designated P16HR025 in 2016 and evaluated in replicated preliminary and advanced yield trials respectively in 2016 and 2017 and subsequently entered in the Variety Registration trials in 2020 and 2021. Breeder seed was established at the F9 generation in 2024.

Tests & Trials: The comparative trials for 'Eternal' were conducted during the 2023 and 2024 growing seasons at the University of Guleph Elora Crop Research Station in Elora, Ontario. The trial included 2 replicates with the plots arranged in a RCB design. Each plot consisted of 2 rows, both 5.5 metres in length and spaced 60cm apart. The seeding density resulted in approximately 400 plants per variety per year. Measured characteristics were based on 40 measurements per variety per year except for seed weight which was based on a minimum of 8 measurements per variety per year. Mean differences were significant at the 5% probability level based on a paired Student's t-test. Disease ratings were provided through the Disease Evaluation team of the Ontario Pulse Crop Committee.
