Variety Description
Varieties used for comparison: 'Windbreaker' and 'ND Palomino'
Summary: ‘XPT One' is a non darkening type pinto bean while ‘Windbreaker' is a darkening type pinto bean and ‘ND Palomino' is a slow darkening type pinto bean. The plants of ‘XPT One' are taller than those of the reference varieties. The plants of ‘XPT One' flower later than the plants of ‘ND Palomino'. At full flowering, the upper side of the leaf of ‘XPT One' is medium green while that of ‘Windbreaker' is dark green. Excluding the beak, the pod of ‘XPT One' is shorter than the pod of ‘ND Palomino'. The pod beak of ‘XPT One' is longer than those of the reference varieties. The main colour on the seed of ‘XPT One' is white while it is beige for the reference varieties.

Origin & Breeding History: ‘XPT One' (experimental designation ME78) originated from a controlled cross conducted in 2014 at the University of Guelph in Guelph, Ontario between the line ACUG 16-NDPI and the variety ‘Stampede'. An F4:6 line was selected in 2016 based on high pod number, upright plant architecture, yield, maturity and suitability to market class. After 3 years of testing the line was designated ME78 and entered into the Variety Registration trials in 2018 and 2020. Breeder seed was established at the F9 generation in 2022.
Tests & Trials: The comparative trials for ‘XPT One' were conducted during the 2022 and 2023 growing seasons at the University of Guleph Elora Crop Research Station in Elora, Ontario. The trial was conducted using a RCB design containing 2 replicates per variety. Each replicate consisted of 2 rows spaced 60 cm apart, with a row length of 5.5 metres. Each plot was 7.15 metres squared resulting in a total of approximately 400 plants per variety per year. Measured characteristics were based on 40 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.
