Abstract
The oat cultivar URS Altiva, developed from the simple cross 'UFRGS 995090-2 x URS 21', and released by the Oat Breeding Program of the Federal University of Rio Grande do Sul (UFRGS) in 2015, presents high grain yield, high grain quality, desirable agronomic performance, and partial resistance to crown rust.
Highlights
The cultivated hexaploid oat (Avena sativa L., 2n = 6x =42, AACCDD) is an important cereal crop used for food, feed, and forage worldwide
The new line achieved grain yield close to or greater than 5% of the best check, which is the main standard established by the Brazilian Oat Research Committee (Comissão Brasileira de Pesquisa de Aveia – CBPA), in order to approve the release of a new oat cultivar using their cooperative trials
The name ‘Altiva’ was selected for this cultivar to highlight its robustness, which results in high grain yield potential, grain quality and resistance to crown rust and lodging, when compared with other oat cultivars currently available in Brazil
Summary
Oat grains contain high amounts of valuable nutrients, such as proteins, soluble fibers (β-glucans), unsaturated fatty acids, vitamins, minerals, and antioxidants. These attributes make oatmeal a functional food with beneficial effects on lowering cholesterol and reducing glycemic response in humans (Ames et al 2014). Oat production is mainly concentrated between the latitudes 23o and 38o S, and between 35o and 55o N In subtropical environments, such as Southern Brazil, oat plays an important role for grain production during the winter/spring seasons in no-tillage crop system rotation, usually with soybeans (Locatelli et al 2007). Breeding method, and agronomic performance of the new released oat cultivar URS Altiva
