URS Brava - a new oat cultivar with partial resistance to crown rust

The cultivar URS Brava, obtained from a simple cross between the line 'UFRGS 995078-2' and the cultivar 'URS 21', shows high grain yield and stability, high grain quality, desirable agronomical traits and partial resistance to crown rust, caused by the fungus Puccinia coronata f. sp. avenae.

Average relative to the best check cultivar, representing the best check within each year of yield test. ^§Average relative to the check cultivar URS 21, which was the best check for grain yield and test weight over the three test years of the new oat line UFRGS 076053-2. *Values shown in brackets for the line UFRGS 076053-2 demonstrate its cultivar performance when compared to the best check within the year of assessment and expressed as a percentage. The locations where the experiments were conducted in the regional yield trial, in 2009 included: Augusto Pestana, Eldorado do Sul, Passo Fundo, Pelotas, Vacaria, Guarapuava, Londrina, Mauá da Serra, Ponta Grossa and Capão Bonito. The locations where the experiments were conducted in the national yield trial of oat lines from the first year, in 2010 included: Augusto Pestana, Eldorado do Sul, Passo Fundo, Pelotas, Guarapuava, Londrina, Mauá da Serra, Ponta Grossa, Capão Bonito and São Carlos. In this year, the data obtained São Carlos were not used in calculating the overall grain yield average due to the high coefficient of variation. The locations where the experiments were conducted in the national yield trial of oat lines from the second year, in 2011 included: Augusto Pestana, Eldorado do Sul, Passo Fundo, Pelotas, Guarapuava, Londrina, Mauá da Serra, Pato Branco, Ponta Grossa and São Carlos. In this year, the data obtained in Pato Branco were not used in calculating the overall grain yield average due to the high coefficient of variation.
