The commercial value of the bovine carcass is determined by a set of traits, such as weight, yield, back fat thickness, and marbling; therefore, the genetic improvement of growth, meat, and carcass quality traits is an important tool to add value to the supply chain. Genomewide association studies (GWAS) enable the identification of loci that control phenotypic expression of quantitative traits (QTL). Therefore, the objective of this work was to perform a GWAS to identify genomic regions and genes associated with growth, carcass traits, and meat quality in Canchim beef cattle. These traits were yearling weight (YW), rib eye area (REA), back fat thickness (BFT), and marbling (MARB). To increase sample size and marker density, genotype imputation was performed, and only markers imputed with greater than 95% accuracy were used. Genomewide association study was performed using a Bayesian approach, by the Bayes B statistical method, incorporating genotypes and phenotypes from 614 animals from both the Canchim breed and the MA genetic group (offspring of Charolais bulls and one-half Canchim + one-half Zebu cows). This investigation identified 1 and 4 genomic regions explaining 0.23 and 7.35% of the genetic variance for REA and YW, respectively. These regions harbor a total of 19 genes, 7 of which were classified for biological functions by functional analysis. Significant associations were not observed for BFT and MARB. The identification of QTL that had been previously described in the literature reinforces associations found in this study.

ABSTRACT - The objective of this work was to determine the storability of 'SCS417 Monalisa' apple fruit in response to harvest maturity, 1-methylcyclopropene (1-MCP) treatment, and storage atmospheres. Fruit quality was evaluated after two, four, six, and eight months plus one day or seven days in shelf life at 22°C. The controlled atmosphere (CA) and 1-MCP (1.0 yL L-¹) treatments reduce fruit ethylene production and respiration, prevent rapid softening, and inhibit the incidence of scald-like symptoms, flesh browning, cracking, and fungal decay, in comparison with air storage . The combination of 1-MCP and CA provides additive benefits in firmness retention and in the reduction of the incidence of physiological disorders. CA and/or 1-MCP increase the risk of fruit developing wrinkly skin disorder. The loss of flesh firmness and acidity and the development of all physiological disorders and decay are higher in late-harvested fruit. The storage life of 'SCS417 Monalisa' apple is about two months in cold air and from six to eight months in cold CA, considering the time necessary to reach a flesh firmness of 53 N. The limiting factor for the long-term storage of 'SCS417 Monalisa' apple fruit under CA without 1-MCP is the development of physiological disorders and fungal decay.
RESUMO - O objetivo deste trabalho foi determinar a armazenabilidade de maçãs 'SCS417 Monalisa' em resposta à maturação na colheita, ao tratamento com 1-metilciclopropeno (1-MCP) e às atmosferas de armazenamento. A qualidade dos frutos foi avaliada após dois, quatro, seis e oito meses mais um dia ou sete dias de vida de prateleira a 22°C. Os tratamentos atmosfera controlada (AC) e 1-MCP (1,0 yL L-¹) reduzem a produção de etileno e a respiração dos frutos, previnem o amolecimento rápido da polpa, e inibem a incidência de escaldadura, escurecimento da polpa, rachaduras e podridões fúngicas, em comparação ao armazenamento ao ar. A combinação de 1-MCP e AC proporciona benefícios aditivos na retenção da firmeza da polpa e na redução da incidência de distúrbios fisiológicos. A AC e/ou 1-MCP aumentam o risco de os frutos desenvolverem o distúrbio superfície rugosa. A perda de firmeza e acidez dos frutos e o desenvolvimento de todos os distúrbios fisiológicos e a podridão são maiores em frutos colhidos tardiamente. O potencial de armazenamento das maçãs 'SCS417 Monalisa' é de cerca de dois meses em ar refrigerado e de seis a oito meses em AC refrigerada, considerando o tempo necessário para atingir a firmeza de polpa de 53 N. O fator limitante para o armazenamento a longo prazo da maçã 'SCS417 Monalisa' sob AC sem 1-MCP é o desenvolvimento de distúrbios fisiológicos e podridões fúngicas.
