Abstract
The development of oat (Avena sativa L.) cultivars with improved grain yield and excellent test weight is necessary to increase the profitability of oat production. ‘Natty’ (Reg. no. CV‐385, PI 676027) was developed by the South Dakota State University (SDSU) oat breeding program and was released in 2014. The pedigree of Natty is SD020701//SD030888/ND030349. Natty exhibited high grain yield potential and excellent test weight when evaluated in the South Dakota Crop Performance Testing Oat Variety Trials and in the Uniform Early Oat Performance Nursery. The grain of Natty is characterized by a large proportion of plump kernels and groats with low beta‐glucan and oil content. Natty is resistant to smut, moderately susceptible to susceptible to crown rust, and moderately tolerant to Barley yellow dwarf virus. Natty is a tall and early‐maturing cultivar suited for the production of oat grain for the feed market. Although its milling quality is good, the low beta‐glucan content of Natty is not desirable for the food market. Based on its height, Natty is also suited for straw production. Three of the oat cultivars released by SDSU were named after Lon Hall's grandchildren; Natty is one of them. Lon Hall was oat breeder at SDSU from 2001 to 2014.
AC Assiniboia is a high-yielding, tan hulled oat cultivar possessing the crown rust resistance gene combination Pc38, Pc39, and Pc68, which is highly effective against the crown rust population on the Canadian prairies at the time of registration. It has very good resistance to loose and covered smut, good resistance to stem rust, and excellent tolerance to Barley Yellow Dwarf Virus (BYDV). AC Assiniboia has good kernel characteristics, including good protein and oil content. AC Assiniboia is well suited for the oat-growing areas of western Canada and in particular the Black soil zone of Manitoba and Saskatchewan.
Despite a significant decrease over the last 50 years, the production of oats (Avena sativa L.) presents both environmental and health benefits. When incorporated in crop rotations, oat has the potential to improve soil health and to break pest cycles in corn (Zea mays L.)–soybean [Glycine max (L.) Merr.] rotations. In addition, the presence of a soluble dietary fiber (b -glucan) in oat grain can help prevent cholesterol, coronary heart diseases, and type 2 diabetes. The development of new oat cultivars with superior productivity and high test weight is required to improve the attractiveness of the crop to producers and to maintain or increase oat production in the United States. ‘Hayden’ (Reg. No. CV-383, PI 676028) is a spring oat cultivar developed at South Dakota State University and released by the South Dakota Agricultural Experiment Station in 2014. The pedigree of Hayden is ‘Buckskin’//ND011054/SD020835. Hayden was developed using a modified bulk and single seed descent selection method. Hayden is a white hulled cultivar with mid-to-late maturity. Hayden was evaluated in the South Dakota Crop Performance Testing Oat Variety Trial from 2013 to 2015 and in the Uniform Mid-Season Oat Performance Nursery in 2013 and 2014 under the experimental number SD111972. Hayden was released because of its excellent yield potential, good yield stability, and high test weight. It is resistant to smut and moderately tolerant to Barley yellow dwarf virus. Hayden also demonstrates good overall milling and nutritional quality.
The landmark approval of the oat health claim by the U.S. Food and Drug Administration marked the first food-specific health claim. Health practitioners are uniquely positioned to recommend that incorporating oats into a diet low in saturated fat is an effective adjunct intervention for reducing the risk of cardiovascular disease. The last decade has witnessed an increase in such research, specifically, the mechanisms of action of oats and unique oat bioactive compounds. Recent interest has extended beyond lipid metabolism to blood pressure lowering, type 2 diabetes, satiety, weight management, and skin health. There is growing concern that the momentum for growing oat intake and research may be hindered as world oat production continues to decline. To reverse this downward trend, there is a need for strategic public and private collaborations to assure sufficient global oat production to meet global demands.
AC Lotta oat (Avena sativa L.) is a daylength-insensitive, spring-type, naked-seeded cultivar suitable for the feed, food (milling) and mixed-grain (oat and barley) industries in eastern Canada. It outyielded the naked seeded check cultivar Tibor by 10% in the Atlantic region, 19% in Quebec and 34% in Ontario in registration trials conducted in 1989 and 1990. It possesses genes conferring resistance to loose smut (Ustilago avenae (Pers.) Rostr.) and to race CR13 of crown rust (Puccinia coronata Cda. f.sp. avenae Eriks. and E. Henn.) and some races of stem rust (Puccinia graminis Pers. f.sp. avenae Eriks. and E. Henn.) in Ontario. It is susceptible to septoria blotch (Septoria avenae Frank f.sp. avenae) and barley yellow dwarf virus (BYDV).Key words: Avena sativa L., daylength insensitive, rust and smut resistance, cultivar description, naked oat
