This is to share with you some key findings from this year’s variety experiments at TBARS Thunder Bay.

Wheat Varieties:

  • Thirty four varieties were evaluated; 9 of which were durum wheat and the rest mostly hard red.
  • Two varieties that gave >7,000 kg/ha grain yield were AAC Chiffon (soft white; 7,214 kg/ha) and Easton (HRS; 7,056 kg/ha). Second best group of varieties in grain yield was SY Rowyn (CPRS; 6,777 kg/ha), Prosper (HRS; 6,550 kg/ha), and CM 9004 (HRS; 6,482 kg/ha).
  • AAC Penhold (last year’s highest yielding variety) gave poor grain yield (5,808 kg/ha) this year!
  • Three top grain yielding durum wheat varieties were CDC Alloy (5,911 kg/ha), CDC Dynamic (5,882 kg/ha) and CDC Carbide (5,617 kg/ha).
  • Highest straw yield (8,586 kg/ha) was obtained with Enterprise (durum wheat), whereas highest biomass yields were registered by Easton (14,594 kg/ha) and AAC Chiffon (14,510 kg/ha).

Barley Varieties:

  • Sixteen high yielding barley varieties (new and proven; 5 two row and 11 six row) were compared for their production potential.
  • Three top grain yielding varieties were Boroe (7,170 kg/ha), Chambly (7,012 kg/ha) and Cyane (6,749 kg/ha). This was true when grain yield was averaged over 2016 and 2017; though the difference between Boroe and Chambly yields was higher in this case.
  • Oceanic (6,610 kg/ha) and Amberly (6,583 kg/ha) formed the second best group in grain yield.
  • Straw (5,165 kg/ha) and biomass (12,176 kg/ha) yields were highest with Chambly.

Malting Barley Varieties:

  • Ten varieties were evaluated.
  • CDC Bow (6,977 kg grains/ha), a new variety, gave over 2 MT/ha higher grain yield than the best yielding AAC Synergy (4,784 kg grains/ha) in the past two years.
  • AAC Synergy was followed closely by CDC Kindersley (4,424 kg/ha). OAC 21, an old variety demanded for craft bear, recorded a grain yield of 3,573 kg/ha.
  • Grain yield of other varieties ranged from 1,846 kg/ha (Newdale; poor stand probably due to bad seed) to 3,717 kg/ha (CDC Copeland).
  • Straw (10,793 kg/ha) and biomass (17, 769 kg/ha) yields were the highest with CDC Bow! AAC Synergy was the second best in straw (6,972 kg/ha) and biomass (11,756 kg/ha) yields.
  • Malting quality this year (grain protein content higher than the accepted 12.0 % in all varieties wasn’t as good as in the previous years; CDC Bow had the lowest grain protein content (12.7 %).

Oat Varieties:

  • Twenty three oat varieties were evaluated for their yield potential.
  • OA 1395-1 recorded the highest grain yield (7,245 kg/ha) followed by OA 1357-2 (6,419 kg/ha) and Vitality (6,417 kg/ha). Two other high yielding varieties were AAC Rosken (last year’s topper; 6,365 kg/ha) and AAC Noranda (6,361 kg/ha).
  • Grain yields of AC Rigodon and AC Jordon, formerly high yielding varieties with stable yields till 2015, were 4,500-5,000 kg/ha only.
  • Among the registered varieties, AAC Richmond produced the highest straw (9,217 kg/ha) and biomass (14,027 kg/ha) yields. Other high straw yielding varieties were AC Dieter (8,868 kg/ha), AC Jordan (8,823 kg/ha) and Vitality (7,435 kg/ha).
  • Selected high yielding varieties were tested for their grain protein content. OA1357-2 (13.9 %) and Vitality (13.6 %) had higher grain protein content than AAC Rosken (12.4 %) and AAC Noranda (10.8 %).

Winter Rye Varieties:

  • Twelve varieties/hybrids were compared for their production potential. There was some winter kill this year and hence the grain yields were lower than that in the previous years.
  • Two hybrids that recorded higher grain yield than Hazlet (4,986 kg/ha) were KWS-H-151 (6,193 kg/ha) and KWS-H-10104 (5,587 kg/ha); though only KWS-H-151 was significantly better than Hazlet.
  • Grain yields of Guttino (3,938 kg/ha) and Brasetto (3,414 kg/ha) were lower than that of Hazlet.
  • KWS-H-151 produced the highest straw (9,560 kg/ha) and the biomass (15,753 kg/ha) yields!

Perennial Rye (Variety Ace-1; seeded in fall 2016):

  • Maximum grain (3,208 kg/ha; 16.1 % protein) and straw (24.3 MT/ha; that is a lot of straw-highest of all crops tested at TBARS so far!) yields were obtained with a seeding density of 400 seeds/m2!
  • Forage dry matter yield increased with the increasing seed rate from 325 seeds/m2 (2.831 kg/ha; 12.1 % protein), to 425 seeds/m2 (3,513 kg/ha) to 475 seeds/m2 (3,811 kg/ha).

Liberty Canola Varieties:

  • Five varieties were compared with each other.
  • L230 recorded the highest seed (7,925 kg/ha; 1,256 kg/ha higher than L252 – last year’s highest yielding variety and 873 kg/ha higher than L5440), straw (12,314 kg/ha) and biomass (20,239 kg/ha) yields.
  • Seed yields of other two varieties were less than the three mentioned in the 2nd bullet and were in the order of L233P (6,734 kg/ha) > L140P (6,014 kg/ha); P in these two varieties stand for ‘Shatter Reduction’.

Round Up Ready/Clearfield Canola Varieties:

  • Five varieties were evaluated.
  • Seed yield ranged from 4,405 kg/ha (73-45 RR; an older variety) to 7,042 kg/ha (6074 RR; a new variety).
  • Next best varieties to 6074 RR in seed yield were 6086 RR (6,550 kg/ha), 6080 RR (6,319 kg/ha) and a Clearfield canola variety 5545 CL (6,013 kg/ha).
  • Straw yield followed a trend similar to the seed yield with 6074 RR producing the highest straw yield (~12 MT/ha).

Mustard Varieties:

  • AC Vulcan (Oriental mustard) recorded higher seed (1,689 kg/ha) and straw (4,535 kg/ha) yields than Adagio (Yellow mustard) – 651 kg/ha seed and 2,576 kg/ha straw.
  • Compared to canola, mustard is a low input crop, is used for culinary purposes, can be sold in retail and fetches higher market price than canola!
