Hail Damage – May 27 2016

• Grain yield and yield stability
• Stress tolerance - drought, high temperatures, winter injury
• Agronomics - plant height, straw strength, maturity, coleoptile

length, shattering tolerance

• Disease and insect resistance - rusts, wheat streak mosaic

virus (WSMV), wheat stem sawfly, Russian wheat aphid (RWA)

• End-use quality
• Physical, structural
• Milling
• Dough mixing
• Bread baking

Breeding Program Objectives

1973 1976 1994 2004 2011 2015 Vona - 34.5 bu/a Baca - 33.1 bu/a Advantage = +1.4 bu/a (16 trials, 1990-95) Akron - 42.3 bu/a Vona - 40.9 bu/a Advantage = +1.4 bu/a (35 trials, 1991-95) Hatcher - 46.8 bu/a Akron - 42.1 bu/a Advantage = +4.7 bu/a (78 trials, 2001-08, 2014-15) Avery - 59.6 bu/a Byrd - 58.0 bu/a Advantage = +1.6 bu/a (43 trials, 2013-15) Byrd - 55.0 bu/a Hatcher - 50.5 bu/a Advantage = +4.5 bu/a (49 trials, 2009-15)

‘Snowmass’ Hard White Wheat (2009) Woodrow, Colorado

Whole Grain Baking Test – CSU Wheat Quality Lab

Wheat Stem Sawfly Stripe rust

Breeding Challenges

• Stripe rust – non issue in Great Plains prior to

2001, evolution of virulent races (2010, 2012)

• Wheat stem sawfly – non issue prior to 2011,

rapidly emerging problem

• Stress tolerance

(drought, heat, winter)

• Dryland, full irrigation,

limited irrigation

• Other pest resistance

traits (RWA, leaf and stem rust, WSMV, etc)

• Herbicide tolerance
• Hard red (HRW) and

hard white (HWW)

• Commodity and

identity preserved production

A Balancing Act

Page 29-33

Hard Red Entries – First Tier

• Prairie Red, Akron – long term checks
• Hatcher – 7 years as #1 in CO acreage survey, yield,

quality, moderate stripe rust resistance

• Byrd – 2 years as #1 in CO acreage survey, #1 in trial

in 2010-12, top 3 2013-14, middle of pack 2015

• Denali – yield, test weight, straw strength
• Avery – new release (2015), 2 days later, larger

kernels/better quality, higher yield potential than Byrd

• TAM 114 (Agseco) – second year in trial, very good in

2015 under heavy stripe rust

Hard Red Entries – Second Tier

• Ruth (Nebraska) – second year in trial, good test

weight, good in 2015 under heavy stripe rust

• Kanmark (KWA) – third year in trial, lower dryland

yields, excellent straw strength for irrigation

• Cowboy (Crop Res Fnd WY) – Denali sib-selection
• TAM 204 (Watley) – beardless (I do not like them...)
• Ripper – 4 years as #2 in CO acreage, on way out
• CSU experimentals – potential release fall 2016
• CO11D1767 – yield, stripe rust resistance
• CO11D446 – yield, test weight, quality, stripe rust

Hard White Entries

• Antero – high dryland and irrigated yield, excellent

stripe rust resistance, no grower premium

• Snowmass – $0.80-1.00/bu grower premium
• Sunshine – $0.40-0.60 premium, improved yield

and stripe rust resistance relative to Snowmass

• CO12D922 – 1 of 5 lines for potential 2017 release

as Snowmass-Sunshine replacements (D922, D906, D1028, D2010, D2011)

• Joe (KWA) – second year in trial, very good in

2015 under heavy stripe rust, quality and sprouting tolerance below average

Clearfield Entries

• Two-gene – enhanced tolerance to Beyond,

allows use of methylated seed oil => feral rye

• Brawl CL Plus – early, good test weight and quality,

intermediate reaction to stripe rust

• Doublestop CL Plus (OK Genetics Inc) – first year in

trial, good stripe rust resistance

• Single-gene – cheat, jointed goatgrass control
• Settler CL (Nebraska) – historically strong performer,

susceptible to new stripe rust races

• Oakley CL (KWA) – fourth year in trial, good yield,

test weight, stripe rust resistance, quality

Wheat Stem Sawfly

Wheat Stem Sawfly Stem Solidness Scale (1-5)

Wheat Stem Sawfly Entries

• Emerging as a serious concern throughout the

west-central Great Plains, including Colorado

• MTS1024 (MT St Univ) – solid stem, very late
• CO11D1397 – CO050337-2/Byrd pedigree
• CSU experimental, potential release fall 2016
• Hollow-stem, has shown some “non-preference”
• High yield & test weight over 2 years at New Raymer
• Low cutting in 2014 (20”+ precip in May 2015…)
• Reduced level of larval infestation in stubble (8-10%

compared to 60-70% in Denali

Private Company Entries

• Limagrain Cereal Seeds
• LCS Mint – yield, test weight, quality, stripe rust
• LCS Chrome – first year entry, leaf/stripe rust resistance
• Westbred (Monsanto)
• Winterhawk – yield, drought tolerance, test weight
• WB-Grainfield – yield, stripe rust resistance
• WB4721 – first year entry, leaf/stripe rust resistance
• Agripro (Syngenta)
• SY Wolf – dryland/irrigated, straw strength, leaf disease
• SY Monument – yield, stripe rust resistance
• SY Sunrise – irrigated, straw strength, certified seed
