“…URS Brava and URS Altiva were released as cultivars in 2014 and 2015, respectively, with phenotypic traits of race-non-specific resistance to crown rust (FEDERIZZI et al, 2015;NAVA et al, 2016). URS Altiva was more susceptible when compared to URS Brava and URS 21.…”

The evolution in virulence of Puccinia coronata f. sp. avenae has challenged the genetic resistance to crown rust in oat genotypes. New resistance sources are constantly required for yield stabilization and costs reduction. This study aimed to characterize the crown rust resistance of oat genotypes and the disease´s productive and economic impact. Experiments were conducted in two environments, with and without chemical control. Resistance was measured by disease progress, apparent rate of infection, final severity and pustule size. Damages were based on reduction of yield, 1000 grain mass and hectoliter mass. UFRGS16Q6030-2 was immune. In both environments, UFRGS166091-2 and URS Brava exhibited the greatest level of resistance and the smallest grain yield reduction, while URS 22 was highly susceptible, reducing more than 70% of its grain yield. These results surpass the negative impacts of the disease previously reported in oats, particularly related to grain yield. The data presented in this paper highlighted the importance of genetic resistance, particularly partial resistance, for maintaining oat genetic yield potential, reducing environmental contamination with less fungicides, and increasing economic gains with oat cultivation.

“…In the Oat Breeding Program at UFRGS we use a pedigree modified as breeding method. The main characteristics and modifications of the breeding method were described by Nava et al (2016). URS MONARCA is a hulled F6-derived line developed from the simple cross UFRGS 06 6083-3 / UFRGS 00 6183-2.…”

“…Panicles from all F1 plants were harvested and bulk-threshed, giving rise to seeds of the second filial generation (F2). The segregating population developed from the cross UFRGS 06 6083-3 / UFRGS 00 6183-2 was advanced and selected from F2 to F6 using a modified pedigree method (Nava et al 2016). All segregating populations were grown in the field in a non-till system during the normal season for the oat crop (planted in June and harvested in October).…”

“…For oat cultivar to be successful in the agronomic systems utilized by the farmers in the subtropical environments it needs to fit perfectly the windows between two summers crops. Earliness is an important trait for subtropical environments such as Southern Brazil, where oat plays an important role in grain production during the winter/spring seasons in no-tillage crop system rotations as a pre-soybean crop (Locatelli et al 2007, Nava et al 2016. The results of UFRGS 146155-3 for the traits related to the crop growth and total cycle are in Table 3.…”

“…The identification of agronomic traits that meet the demand of farmers, industry quality and final consumers, and their incorporation into elite oat germplasm are crucial to the development of successful new oat cultivars. Some of the most important traits selected by the Brazilian Oat Breeding Program include wide adaptation, high grain yield and grain quality, short plant cycle, reduced plant height, lodging resistance, frost tolerance, aluminum tolerance, and genetic resistance to the main diseases, such as crown and stem rust, leaf spot, fusarium, and barley yellow dwarf virus [4]. In this research the use of a mixture of fungicides claimed to have growth retardant effect is explored aiming a better assessment of yield attributes and quality parameters of oats.…”

Triazoles and strobilurins group of fungicides have been reported to have dual properties (growth regulator and fungicide) and have been used to prevent the plant lodging. In this study four subsequent field experiments with oat cultivars with and without fungicide application were conducted from 2012 to 2015 aiming to find if fungicide application can improve some yield attributes and quality parameters of oats and find yield attributes that most affect the quality parameters of oats. Multivariate techniques were applied in other to find the most important variables that contribute to sample classification. Fungicide application has a role in reducing the plant stature of oat cultivars with consequent decreasing in lodging index of oat cultivars. Fungicide
