Summary: The plants of '641512175' are an alternative type while the plants of 'AAC Delight' and 'Tyndal' are spring type. The plants of '641512175' head earlier than the plants of '934271498' and later than those of 'AAC Delight' and 'Tyndal'. The flag leaf sheath of '641512175' has strong glaucosity while that of '934271498' has medium glaucosity. At anthesis, the flag leaf of '641512175' is longer than the flag leaf of '934271498'. At full stem extension, the plants of '641512175' are taller than the plants of the reference varieties. The spike of '641512175' is awnless while those of 'AAC Delight' and 'Tyndal' are half awned. Excluding the awns, the spike of '641512175' is longer than those of the reference varieties. The first beak on the lower glume of '641512175' is medium to long while those of the reference varieties are short to medium length. The lower glume of '641512175' has hairs present on the external surface while hairs are absent on the lower glumes of the reference varieties. The kernel of '641512175' is amber while that of 'AAC Delight' is red. The kernel of '641512175' has medium colouration with phenol while the kernel of 'AAC Delight' has none or very light to light colouration with phenol and those of '934271498' and 'Tyndal' have strong colouration with phenol.

Description:

PLANT: hexaploid, alternative type, semi-erect growth habit at tillering, high to very high frequency of plants with recurved flag leaves at booting, heads mid-season

FLAG LEAF: medium intensity of anthocyanin colouration on auricles, strong glaucosity of sheath

CULM: slightly to moderately curved neck, very dense pubescence
STRAW (STEM): thick pith in cross-section

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

KERNEL: amber, medium to large, medium to long, medium width, elliptical shape, medium colouration with phenol

Origin & Breeding History: '641512175' (experimental designation RSI 202567) originated from a cross conducted prior to 2001 between a proprietary parental line designated as 49816AM and the variety 'TriCal 2700' in the Resource Seeds International Triticale Breeding Program in Woodland California, USA. In 2001, 19 sister lines resulting from the cross were planted in Vega, Texas, USA with 2 of the lines selected and planted at several locations in Kentucky, Nebraska, Texas, Washington and Wisconsin, USA for observation from 2002 to 2004. After being shelved from 2005 to 2007, replicated silage trials resumed in Othello, Washington for one of the lines, from 2010 to 2016. In 2015, 15 progeny rows were identified as uniform and true to type and grown in progeny plots. Three plots were selected in 2016 and bulked to form breeder seed. '641512175' was selected based on forage production.

Tests & Trials: The comparative trial for '641512175' 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 metre inter-row spacing. 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 201700387, purchased from the Plant Variety Protection Office in Washington, District of Columbia, USA.
