Maize topcrosses for yield performance by additive main effects and multiplicat...
Rosa,Jocimar Costa; Scapim,Carlos Alberto; Faria,Marcos Ventura; Uhdre,Renan Santos; Zaluski,Welton Luiz; Sagae,Vitor SeitiABSTRACT: The analysis of main additive effects and multiplicative interaction is commonly used in the evaluation of the genotype x environment interaction, however, its application can be used for other purposes, as it is performed in the presentresearch, which uses this technique in the selection of inbred lines, testers and hybrids in maize topcrosses. Thisresearch determined the effect of the inbred lines x...
Effect of storage time on the chemical composition of whole and grainless corn ...
Souza,André Martins de; Neumann,Mikael; Rampim,Leandro; Almeida,Eduardo Rodrigues de; Matchula,Angela Fernanda; Cristo,Fernando BragaABSTRACT The objective of this study was to evaluate the effect of harvesting corn at different maturity stages for silage production combined with four storage periods, considering nutrient loss and the chemical composition of silage of the whole plant and also of grainless plants. The experiment was performed in a completely randomized design with a factorial arrangement of six maturity stages of corn [reprod...
Yield related key traits in the selection of super sweetcorn hybrids
Zaluski,Welton Luiz; Faria,Marcos Ventura; Rosa,Jocimar Costa; Uhdre,Renan Santos; Sagae,Vitor Seiti; Chiquito,Nathany Ribeiro; Gava,EmanuelABSTRACT Super sweet corn breeding must develop hybrids that fully meet the expectations of the market. In this sense, the determination of keytraits for the selection of sweetcorn genotypes is a fundamental condition for breeding success. The objective of this work was to identify key traits for the selection of promising and contrasting genotypes of super sweet corn. The experiments were carried out in Guarap...
Combining ability and genetic divergence in the selection of testers regarding ...
Rosa,Jocimar Costa; Faria,Marcos Ventura; Zaluski,Welton Luiz; Uhdre,Renan Santos; Andreoli,Pedro Henrique Willemann; Sagae,Vitor SeitiABSTRACT Genetic divergence analysis among testers and progenies and the correlation of genetic distance with combining ability can be an important alternative to select maize progenies regarding grain yield and forage potential since testers suitable to both purposes are rare.The objective of this work was to select testers suitable for the evaluation of grain yield and forage traits is topcrosses with S3 prog...
Forage potential of S3 corn progenies in topcrosses and selection of testers of...
Rosa,Jocimar Costa; Faria,Marcos Ventura; Zaluski,Welton Luiz; Gava,Emanuel; Andreoli,Pedro Henrique Willemann; Sagae,Vitor SeitiAbstract: The objective of this work was to identify corn (Zea mays) genotypes with forage potential and to evaluate the efficiency of testers to discriminate forage traits in topcrosses, considering the contribution of additive and nonadditive genes. The experiment was carried out in the 2015/2016 and 2016/2017 crop seasons, in a randomized complete block design with three replicates. Thirty S3 corn progenies ...
Selection of corn inbred lines, testers, and hybrids adapted to second-crop env...
Gomes,Rodrigo; Faria,Marcos Ventura; Rosa,Jocimar CostaAbstract: The objective of this work was to evaluate the yield performance, adaptability, and stability of corn (Zea mays) topcross hybrids in nine environments in Brazil, in order to select inbred lines, testers, and promising hybrid combinations for these environments in the second crop season. The trials were carried out during the second crop season of 2017, in six sites in the state of Paraná and three in ...
Combining ability of physiological traits in forrage maize
Redivo,Greice Daiane Rodrigues Gomes; Faria,Marcos Ventura; Rosa,Jocimar Costa; Ono,Elizabeth Orika; Rodrigues,João Domingos; Adriano,ElisaABSTRACT The exploitation of the existing genetic variability for the physiological traits related to the yield and quality of maize forage can assist in the development of superior inbred lines and hybrids. The objective of this work was to evaluate the general and the specific combining ability and the nature of gene effects of physiological and chemical traits of forage maize genotypes. Two groups of genotyp...
Base temperature for node emission and plastochron determination in tomato spec...
Zeist,André Ricardo; Resende,Juliano Tadeu Vilela de; Faria,Marcos Ventura; Gabriel,André; Silva,Israel Felipe Lustosa da; Lima Filho,Renato Barros deAbstract: The objective of this work was to estimate the base temperature for node emission and plastochron determination in wild species of tomato, in the Redenção cultivar, and in their respective interspecific F1 hybrids. The wild accessions Solanum pimpinellifolium AF 26970, Solanum galapagense LA-1401, Solanum peruvianum AF 19684, Solanum habrochaites var. hirsutum PI-127826, Solanum habrochaites var. glab...
Combining ability and heterosis of relevant fruit traits of tomato genotypes fo...
Figueiredo,Alex Sandro Torre; Resende,Juliano Tadeu Vilela de; Faria,Marcos Ventura; Paula,Juliana Tauffer de; Schwarz,Kélin; Zanin,Daniel SuekThe objective was to estimate the combining ability of lines and heterosis in industrial tomato genotypes for the identification of those with good potential for breeding programs. Ten lines of industrial tomato, 45 hybrids derived from a complete diallel and two commercial check cultivars were evaluated. The combining ability of tomato lines and heterosis of hybrid combinations for fruit-quality related traits...
