URS Altiva - a new oat cultivar with high agronomic performance

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.

Key words:
Avena sativa L.; oat breeding program; crown rust
