O objetivo deste trabalho foi avaliar os efeitos da aplicação de concentrações do regulador crescimento etil-trinexapac na altura planta, no acamamento e produtividade grãos cultivar aveia-branca Barbarasul, em diferentes ambientes cultivo doses nitrogênio. Os experimentos foram conduzidos nas safras 2010 2011 nos municípios Capão Leão Augusto Pestana, Estado Rio Grande Sul, 2012 Município Lages, Santa Catarina. Utilizou-se o delineamento blocos ao acaso, arranjo fatorial 4x2x6 (dose...
Abstract Crown rust, caused by Puccinia coronata f. sp. avenae Erikss., is the most important disease impacting cultivated oat ( Avena sativa L.). Genetic resistance desirable management strategy. The genetic architecture of crown rust not fully understood, and previous mapping investigations have mostly ignored temporal variation. A collection elite lines sourced from breeding programs in American Upper Midwest Canada was genotyped using a high‐density genotyping‐by‐sequencing system...
Abstract Predicting phenotypes from a combination of genetic and environmental factors is grand challenge modern biology. Slight improvements in this area have the potential to save lives, improve food fuel security, permit better care planet, create other positive outcomes. In 2022 2023 first open-to-the-public Genomes Fields (G2F) initiative Genotype by Environment (GxE) prediction competition was held using large dataset including genomic variation, phenotype weather measurements field...

Indirect selection can be considered an interesting strategy for plant breeding, especially when easily measurable/high heritability trait is highly correlated with a target which has lower in segregating populations. The objective of this study was to obtain estimates phenotypic, genotypic and environmental correlations evaluate the partition direct indirect effects agronomic variables on GY variable, through analysis two cultivated environments fifteen wheat traits grain yield per (GY),...
Abstract Kernel shape and β‐glucan content are important attributes for oat ( Avena sativa L.) millers. The identification of genomic regions controlling these traits, as well their effect on phenotype, will enable rapid gain from selection. objectives this study were (a) to identify the associated with kernel in an panel adapted subtropical environments (b) clarify relationship between oat. An elite comprising 406 inbred lines was assessed Londrina Eldorado do Sul, Southern Brazil....
Abstract:The objective of this work was to characterize the performance elite wheat genotypes from different Brazilian breeding programs for traits associated with grain yield and preharvest sprouting. The study conducted in 2010 2011 municipality Capão do Leão, state Rio Grande Sul, Brazil, a randomized complete block design three replicates. Thirty-three were evaluated related sprouting yield. estimate genetic distance used predict potential combinations selection plants high tolerance...
Selection for heading date has been a decisive factor to increase areas cropped with oats in Brazil. Although important oat breeders, genomic regions controlling have not completely identified. The objective of this study was identify subtropical environments. A set 412 genotypes, developed from 1974 2015, assessed contrasting environments and genotyped using genotyping–by–sequencing (GBS). Phenotypic genotypic data were used single multi–environment association models. Quantitative trait...
The delayed leaf senescence (stay-green) has been frequently attributed to significant yield gains in different crops, especially under stress conditions. goal of the study was elucidate if wheat plant through expression stay-green character brings effective contributions adaptability and stability parameters for weight a thousand grains, aiming genetic selection more stable productive genotypes. experiment conducted on years 2003, 2004 2005 field experimental design random blocks with three...
Abstract Multiflorous spikelets are found in oat Avena sativa L. subsp. nudisativa , which is characterised by elongated rachilla and variable number of florets per spikelet. One the main factors limiting exploration multiflorous oats, aiming to produce naked grains, its expressivity. This work aimed detect environmental influence on expressivity spikelet formation oats estimate heritability this trait analysing expression lower, middle upper third panicle 94 inbred lines two crosses each....
Pre-harvest sprouting (PHS) harms the quality of wheat by converting starch into sugar and decreasing flour quality.Therefore, improving genotypes for PHS is critical Brazilian breeding programs.The goals this study were to evaluate combining ability heterosis genotypes, aiming increase genetic gains identify promising combinations capable generating superior grain yield pre-harvest tolerance.The work was conducted in 2011 Capão do Leão, RS, Brazil, under an experimental design randomized...
Multiflorous spikelets are found in several grass species of agricultural and economic interest. In oat, this morphological characteristic is associated with the production naked grains. Although many genetic studies have been performed over past century, inheritance multiflorous spikelet trait not fully understood oat. The objectives study were to evaluate environmental effects on trait, estimate number genes controlling clone characterize sequences AP2 gene Two populations recombinant...
