Variety Description

Varieties used for comparison: 'Hobson' and 'HY 124-HRS'

Summary: 'HY 017-HRS' has absent or very weak anthocyanin colouration of the coleoptile whereas 'Hobson' has weak to moderate anthocyanin. The plants of 'HY 017-HRS' mature later than those of 'HY 124-HRS'. At the four leaf stage, pubescence of the lower leaf blade is absent for 'HY 017-HRS' whereas it is sparse for 'Hobson' and sparse to moderately dense for 'HY 124-HRS'. The flag leaf of 'HY 017-HRS' is shorter than that of 'Hobson', longer than that of 'HY 124-HRS' and more narrow than that of both reference varieties. Anthocyanin colouration of the flag leaf auricles of 'HY 017-HRS' is absent or very weak while it is strong to very strong for 'Hobson'. At maturity, 'HY 017-HRS' has a more weakly curved culm than 'HY 124-HRS'. The spike length for 'HY 017-HRS' is shorter than that of 'Hobson' and longer than that of 'HY 124-HRS'. The lower glume of 'HY 017-HRS' has a narrower shoulder and shorter beak than that of 'Hobson'. 'HY 017-HRS' has a smaller germ than both reference varieties.

Description:

PLANT: spring wheat, semi-erect to intermediate growth habit, low to medium frequency of plants with recurved flag leaves, matures mid-season to late

Origin & Breeding History: 'HY 017-HRS' (experimental designation 98S017-01) is a spring wheat variety that was bred and developed by Agripro-Coker (A Division of Syngenta Seeds) in Berthoud, Colorado, USA, from a cross made in 1998 between lines 'Lars/3/N92-0098' and 'Sumai-3/Dalen'. A modified single seed descent breeding method was used to develop 'HY 017-HRS'. The line was selected as an F4 and in the spring of 2003, seed was first tested by Hyland Seeds as an F6. From 2003 to 2006, further assessment, selection and advancement of 'HY 017-HRS' was based on its reaction to the available leaf and stem diseases, straw strength, height, and seed and other agronomic and quality characteristics. Also from 2003 to 2006, 'HY 017-HRS' was tested in both private and public trials where enough information was acquired to support its registration.

Tests & Trials: Tests and trials were conducted during 2010 and 2011. The plot for each of these years was planted at the St. Mary's Testing Location in the spring of 2010 and 2011. The plots were planted at a rate of 400 seeds/square metre, 4 metres long and consisted of four replicates. In the spring, plots were cut back to 3 metres and finally consisted of 5 x 23 cm rows in 2010 and 6 x 16 cm rows in 2011. The total plot area was 1.38 metres x 3 metres = 4.14 metres which resulted in a minimum of 1650 plants/plot grown/replicate.
