The 6 new varieties include:
- reduced awn winter triticale - WT0006
- 2 malting barleys - TR14617 and TR17635
- nitrogen efficient feed and forage 6-row barley - SR18524
- 2-row feed and forage barley - TR18647
- general purpose barley - TR18645
“A nitrogen (N) efficient variety takes up more N from the soil or utilizes N more efficiently to maximize yield,” says Yadeta Kabeta, research scientist at the Field Crop Development Centre (FCDC).
“This can mean lower input costs, more stable yield and less N lost to the environment. Our new variety SR18524 has 6 to 10% more N use efficiency than check varieties.”
Agronomically, this line is a smooth awned semi-dwarf type, with 3% higher grain and forage yields than the available semi-dwarf 6-row varieties Amisk and Vivar.
The two 2-row feed and forage varieties to be released this spring, TR18645 and TR18647, were the 2 highest yielding lines in the 2-row pre-registration Cooperative tests in the 2018 drought year. TR18647 was bred specifically for feed and has superior forage production and quality. Over the 2 years of testing in the Cooperative trials, TR18645 and TR18647 had about 4% and 6% higher grain yield than CDC Austenson.
Also available is the only non-glycosidic nitrile (non-GN) malting barley in Canada.
“GN is a precursor to ethyl carbamate, a carcinogen, which can concentrate during distillation to undesirable levels,” explains Pat Juskiw, plant breeder at the FCDC. “This isn’t an issue for non-GN barley, like TR14617”.
