  • Adaptabilidade e estabilidade da produção de café beneficiado em Coffea canephora
    Rocha, Rodrigo Barros; Ramalho, André Rostand; Teixeira, Alexsandro Lara; Souza, Flávio de França; Cruz, Cosme Damião (Universidade Federal de Santa Maria, 2015-09)
    O objetivo deste trabalho foi comparar a capacidade discriminatória de métodos para seleção e recomendação de clones de cafeeiros da espécie Coffea canephora, considerando a interação genótipos x anos na distribuição da ...
  • Adaptability and stability of Coffea canephora Pierre ex Froehner genotypes in the Western Amazon
    Moraes, Marcos Santana; Rocha, Rodrigo Barros; Teixeira, Alexsandro Lara; Espindula, Marcelo Curitiba; Silva, Camila Andrade; Lunz, Aureny Maria Pereira (Universidade Federal de Santa Maria, 2020)
    The development of Coffea canephora cultivars is based on the characterization of genotype × environment interaction, which is interpreted to quantify the differential behavior of clones at different cultivation sites. The ...
  • Coffea canephora breeding: estimated and achieved gains from selection in the Western Amazon, Brazil
    Rocha, Rodrigo Barros; Teixeira, Alexsandro Lara; Ramalho, Andre Rostand; Espindula, Marcelo Curitiba; Lunz, Aureny Maria Pereira; Souza, Flavio de França (Universidade Federal de Santa Maria, 2021)
    Gain from selection is an important criterion in quantifying the efficiency of breeding programs. This study quantified the selection gain estimated under experimental conditions and realized gain achieved in the field, ...
  • Genetic progress with selection of Coffea canephora clones of superior processed coffee yield
    Silva, Dulcilene Oliveira da; Ferreira, Fábio Medeiros; Rocha, Rodrigo Barros; Espindula, Marcelo Curitiba; Spinelli, Victor Mouzinho (Universidade Federal de Santa Maria, 2018-03)
    The aim of this study was to select Coffea canephora clones of superior processed coffee productivity based on the estimates of the genetic parameters and of genetic progress with the plant selection. For this, the production ...
  • Selection of arabica coffee progenies tolerant to heat stress
    Teixeira, Alexsandro Lara; Souza, Flávio de França; Pereira, Antonio Alves; Oliveira, Antonio Carlos Baião de; Rocha, Rodrigo Barros (Universidade Federal de Santa Maria, 2015-07)
    Due to high temperatures, practically all coffee farms in the state of Rondonia are of the C. canephora species. Thus, importing arabica coffee from other states becomes necessary for composition of blends, as well as for ...
  • Selection of Coffea canephora parents from the botanical varieties Conilon and Robusta for the production of intervarietal hybrids
    Oliveira, Leilane Nicolino Lamarão de; Rocha, Rodrigo Barros; Ferreira, Fábio Medeiros; Spinelli, Victor Mouzinho; Ramalho, André Rostand; Teixeira, Alexsandro Lara (Universidade Federal de Santa Maria, 2018-04)
    The objective of this research was to quantify the genetic divergence of potential Coffea canephora parents, with the goal of developing progenies that associate the best traits of the Conilon and Robusta botanical varieties ...
