Origin & Breeding History: 'ND Palomino' originated from a controlled cross conducted in the winter of 2008 in a greenhouse in Prosser, Washington, USA between 'Sante Fe' and the breeding line PSO8-103. From 2009 to 2011, plants were grown and advanced using single seed descent and plantings alternated between a greenhouse in Prosser, Washington and a field in Othello, Washington to develop a recombinant inbred line population. In the summer of 2011, breeding line SF103-8 advanced based on plant architecture, seed quality and yield potential. From 2012 to 2015, multi-location yield testing, greenhouse disease evaluations and canning quality tests occurred across 22 environments in North Dakota, USA. From 2013 to 2014, breeder seed increases occurred in New Zealand and Washington, Wyoming and Idaho, USA.

Tests & Trials: The comparative trial for 'ND Palomino' was conducted during the 2022 growing season at Canterra Seeds in Portage la Prairie, Manitoba. The trial was conducted using a RCB design containing 3 replicates per variety. Each replicate consisted of 5 rows spaced 30 cm apart, with a row length of 5 metres. Each plot was 7.1 metres squared with a total of approximately 255 plants per variety. Measured characteristics were based on 20 measurements per variety, except seed weight which was based on 4 measurements of 100 seeds each per variety. Mean differences were significant at the 5% probability level based on a paired Student`s t-test. Results were supported by the official technical examination report 201700085, purchased from the Plant Variety Protection Office in Beltsville, Maryland, USA.
