SDSU releases new hard red winter wheat variety
During that same time period, Redfield was also tested in seven locations east of the Missouri River in South Dakota. In those test trials, Redfield and Lyman both yielded 65.3 bushels per acre; which was less than cultivar, Overland, which yielded 69.4 bushels per acre, but more than cultivar, Wesley which yielded 63.6 bushels per acre.
Redfield's test weights were similar to Overland and significantly higher than Wesley. Protein concentrations were intermediate between Wesley and Overland.
As an experimental line, Redfield was evaluated in the Northern Regional Performance Nursery from 2010 to 2013. From 2010 to 2012, it consistently ranked in the top 5 for mean grain yield across all NRPN locations.
Redfield is shorter than Overland, but approximately 1-inch taller than Wesley. Redfield exhibits the same excellent lodging resistance as Wesley, which is better than Overland.
Redfield is a mid-maturity type, typically flowering approximately one day later than Overland and two to three days later than Wesley.
Its winter hardiness is expected to be as good as, or better than Wesley, providing more versatility where less protective cover exists in South Dakota and opportunities for movement north into North Dakota and Montana.
In the regional Fusarium Head Blight (FHB) Nursery, Redfield exhibited similar resistance to FHB as Overland. Similar to Wesley, it is moderately susceptible to leaf rust; moderately susceptible to susceptible to stem rust; moderately susceptible to moderately resistant to stripe rust; and susceptible to Wheat Streak Mosaic Virus.
Redfield was evaluated by the Wheat Quality Council from 2010 to 2012. It exhibited average to good milling quality and was better than Lyman in overall baking quality.
