“…The differentiation in trials with and without fungicide use was also observed in wheat, which showed higher genetic progress in trials without fungicide, indicating that breeding programs aimed at releasing disease-resistant cultivars present additive effects on grain yield (Oury et al, 2012).…”

“…For the oat crop, the studies developed by Barbosa Neto et al (2000) in Brazil and by Redaelli et al (2008) in Italy can be emphasized. In addition, the studies with cereals from the same family as wheat (Nedel, 1994;Rodrigues et al, 2007;Cargnin et al, 2008;Oury et al, 2012;Beche et al, 2014;Thomas and Graf, 2014;Wu et al, 2014), rice (Borges et al, 2009;Breseghello et al, 1999Breseghello et al, , 2011DoVale et al, 2012), and popcorn (Ribeiro et al, 2012) can be highlighted.…”

“…Dividing the cultivar trials with and without fungicide use is relevant. In France, different estimates of genetic progress were obtained for wheat cultivars grown with and without fungicide use (Oury et al, 2012). In Brazil, differences in oat trials with and without fungicide use have been reported in the studies of cultivar stability and adaptability (Lorencetti et al, 2004) and stratification of environments (Benin et al, 2005).…”

ABSTRACT. The State of Rio Grande do Sul (RS) is the largest producer of oat in Brazil with the aid of consolidated breeding programs, which are constantly releasing new cultivars. The main objectives of this study were to: 1) evaluate the annual genetic progress in grain yield and hectoliter weight of the oat cultivars in RS, with and without fungicide use on aerial parts of plants; and 2) evaluate the efficiency of oat breeding programs in introducing disease-resistant genes in the released cultivars through network yield trials conducted with and without fungicide use on aerial plant parts. The data on grain yield and hectoliter weight were obtained from 89 competition field trials of oat cultivars carried out from 2007 to 2014 in nine municipalities of RS. Of the total 89 trials, 44 were carried out with fungicide application on aerial plant parts and 45 were carried out without fungicide application. The annual genetic progress in oat cultivars was studied using the methodology proposed by Vencovsky (1988). The annual genetic progress in oat grain yield was 1.02% with fungicide use and 4.02% without fungicide use during the eight-year study period in RS. The annual genetic progress with respect to the hectoliter weight was 0.08% for trials with fungicide use and 0.71% for trials without fungicide use. Performing network yield trials with and without fungicide use on the aerial plants parts is a feasible method to evaluate the efficiency of oat breeding programs in introducing disease-resistant genes in the released cultivars.

“…Genetic progress studies have been performed with wheat (Nedel, 1994;Rodrigues et al, 2007;Cargnin et al, 2008;Oury et al, 2012;Beche et al, 2014;Thomas and Graf, 2014;Wu et al, 2014;Gummadov et al, 2015) and cereals from the same wheat family, including oat (Barbosa Neto et al, 2000;Redaelli et al, 2008) and rice (Borges et al, 2009;Breseghello et al, 1999Breseghello et al, , 2011DoVale et al, 2012). It is assumed that there was genetic progress for wheat grain yield in RS influenced by homogeneous regions of cultivation.…”

ABSTRACT. The State of Rio Grande do Sul (RS) stands out as the largest wheat producer in Brazil. Wheat is the most emphasized winter cereal in RS, attracting public and private investments directed to wheat genetic breeding. The study of genetic progress should be performed routinely at breeding programs to study the behavior of cultivars developed for homogeneous regions of cultivation. The objectives of this study were: 1) to evaluate the genetic progress of wheat grain yield in RS; 2) to evaluate the influence of cultivar competition trial stratification in homogeneous regions of cultivation on the study of genetic progress. Grain yield data of 122 wheat cultivars evaluated in 137 trials arranged in randomized block design with three or four replications were used. Field trials were carried out in 23 locations in RS divided into two homogeneous regions during the period from 2002 to 2013. Genetic progress for RS and homogeneous regions was studied utilizing the method proposed by Vencovsky. Annual genetic progress for wheat grain yield during the period of 12 years in the State of RS was 2.86%, oscillating between homogeneous regions of cultivation. The difference of annual genetic progress in region 1 (1.82%) in relation to region 2 (4.38%) justifies the study of genetic progress by homogeneous regions of cultivation.

“…This helps breeders in decision-making process to define appropriate goals and strategies for selecting cultivars with specific baking quality to meet the market requirements. Two ways to estimate the genetic gain are often used in evaluating the efficiency of breeding programs: i) conducting experiments with old and modern cultivars (Matus et al, 2012;Cormier et al, 2013, Bilgin et al, 2015, and ii) using data from multi-environment trials (Cargnin et al, 2008;Oury et al, 2012, CrespoHerrera et al, 2017. This last option is more attractive because it does not require a specific experimentation process, but just the data already available.…”

In wheat (Triticum aestivum L.) several studies have reported genetic gain for grain yield over the years. However, studies on wheat bread-making quality are scarce. Our objective was to estimate the progress due to genetic and environmental components in wheat breadmaking quality parameters. In addition, we aimed to examine trends in historical cultivars and associate traits performance with geographical parameters. We used data from multi-environment trials (MET) represented by eight years (2005)(2006)(2007)(2008)(2009)(2010)(2011)(2012) and 458 genotypes, including lines and commercial cultivars (controls). We determined the genetic progress by the contrasts between genotypes assessed in each biennium, excluding the year effect. This effect is previously estimated by existing variation among common genotypes. Genotype replacement rate was 52% and reflects the dynamism of the breeding program to develop better genotypes in terms of bread-making quality. The genetic progress estimated for gluten strength (W) was 1.30% yr -1 . The progress in W demonstrated to be partly counterbalanced by the environmental effect (-0.78% yr -1 ). We observed disequilibrium tendency in relationship between tenacity and extensibility (P/L ratio) as a consequence of searching for lines with high W. Analysis showed that P/L ratio can be reduced in responses to the increase in latitude of the location. Environmental and genetic effects on the traits variation were discussed.
