Accelerate

Wheat

Variety Description

Varieties used for comparison: 'MSCHEVELLE' and 'AAC Penhold'

Summary: At maturity, the plants, including the spike and awns, of 'Accelerate' are taller than the plants of the reference varieties. The awns of 'Accelerate' are shorter than the spike whereas the awns of 'MSCHEVELLE' are equal to the length of the spike. The lower glume shoulder of 'Accelerate' is of medium width whereas the lower glume shoulder of 'MSCHEVELLE' is narrow. The lower glume of 'Accelerate' is short to medium in length and narrow to medium in width whereas the lower glume of 'AAC Penhold' is long and wide. The lower glume beak of 'Accelerate' is short whereas the lower glume beak of 'MSCHEVELLE' is of a medium length and that of 'AAC Penhold' is medium to long.

GERM: elliptical to broad elliptical in shape

Origin & Breeding History: 'Accelerate' (experimental designations LNR14-1299 and HY2077) was developed using a modified bulk breeding method. In 2011, a cross was conducted between the proprietary lines LNR10-0146 and LNR10-0177 in Fort Collins, Colorado, USA with the resulting F1 grown in Yuma, Arizona. From 2012 to 2014, the line was advanced from the F2 to the F4 generation with F5 selections grown as head rows for seed stock in Yuma, Arizona during the 2013-2014 growing season. Pre-breeder seed production commenced in Colorado, USA, in 2016. The variety was concurrently evaluated in mutiple locations across the USA and Canada in 2015 and was entered in the High Yield Wheat Cooperative Registration Trials as LNR14-1299 from 2016 to 2018. 'Accelerate' was selected based on grain yield and stability, maturity, lodging resistance, plant height and disease resistance as well as end use characteristics such as protein content, milling performance, starch quality, gluten strength, gluten extensibility, baking and pasta quality.

Tests & Trials: The comparative trials for 'Accelerate' were conducted at Limagrain Cereals Research Canada in Saskatoon, Saskatchewan during the 2020 and 2021 growing seasons. There were a minimum of 3 replicates per variety in each year, arranged in an RCB design. Each plot was 4.5 square metres and consisted of 6 rows, 3.0 metres in length with 0.22 metre inter-row spacing. The seeding density resulted in 250 plants per square metre, resulting in a minimum of 3,375 plants per variety per year. Measured characteristics were based on a minimum of 40 measurements per variety per year. Mean differences were significant at the 5% probability level based on paired Student's t-tests.
