CULM: straight to slightly curved neck, very dense pubescence
STRAW (STEM): medium thickness of pith in cross-section

SPIKE: very strong glaucosity, awnless, white at maturity, medium to dense, medium width in profile
ANTHERS: absent or very weak intensity of anthocyanin colouration
LOWER GLUME: short to medium length first beak, absent or very small to small second beak, hairs absent on external surface

KERNEL: amber, medium sized, medium length and width, elliptical shape, dark colouration with phenol

Origin & Breeding History: '934271498' (experimental designation APT1426023) originated from a cross conducted in 2005 between two unreleased experimental lines designated 04TF 107 and 04TF 104 in the Resource Seeds International Triticale Breeding Program in Fort Collins, Colorado, USA. Early generation selections were made using a pedigree breeding method based on plant height, maturity, disease tolerance, straw strength and awnedness. In 2014, an F4:F5 headrow designated as APT1426023, was bulk harvested and tested for grain yield, boot stage silage yield and vegetative forage production in multiple locations in Texas, Montana, New York, Washington and Idaho from 2015 to 2019. Simultaneously, a seed purification program, using head to row techniques, was used to identify rows that were uniform and true to type. Head rows were selected in 2016 and planted in Yuma, Arizona as progeny plots in 2018. In 2019, 2 progeny plots were bulk harvested and planted in Yuma to produce breeder seed.

Tests & Trials: The comparative trial for '934271498' was conducted during the 2021 growing season at Ag-Quest in Taber, Alberta. The trial was arranged in a RCB design with 2 replicates. Each plot consisted of 6 rows with a row length of 6 metres and 0.2 metres between rows. The seeding density was approximately 320 grains per squared metre resulting in approximately 3945 plants per variety. Measured characteristics were based on 20 measurements 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 202000217, purchased from the Plant Variety Protection Office in Washington, District of Columbia, USA.
