F4 coffee progenies selection obtained from ICATU group cultivars
Pereira, Thamiris Bandoni; Mendes, Antônio Nazareno Guimarães; Botelho, César Elias; Rezende, Juliana Costa de; Vilela, Diego Júnior MartinsThe objective of this study was to select, for agronomical features and resistance to diseases, F4 generation coffee progenies, obtained from Icatu cultivars. The experiment was conducted in the EPAMIG Experimental Farm (Fazenda Experimental da EPAMIG), in Machado- MG, using progenies derived from the crossing between Icatu with Catuaí Amarelo IAC 62 e IAC 17 cultivars and the IAC 5002 e IAC 5010 progenies. The...
Grafted coffee growth in mineral nutrient solution
Ferreira, André Dominghetti; Rezende, Ramiro Machado; Rezende, Juliana Costa de; Carvalho, Gladyston Rodrigues; Carvalho, Alex Mendonça deThe use of grafting in coffee, and give greater tolerance for nematodes, have shown influence on the growth of coffee, so the purpose of this study was to evaluate the growth of different varieties of Coffea arabica L. grafted into Apoatã IAC 2258 (Coffea canephora). The experiment was installed in a greenhouse, using the method of cultivation in nutrient solution. It used a factorial 7 x 3 + 2, and seven culti...
Coffee genotypes reaction for resistance to Meloidogyne exigua South of Minas G...
Pereira, Thamiris Bandoni; Salgado, Sonia Maria Lima; Carvalho, Gladyston Rodrigues; Pereira, Antonio Alves; Dominghetti, André FerreiraThe use of resistant cultivars is an economical and efficient method to prevent nematode infestation in coffee plantations. The progress of coffee resistance to Meloidogyne exigua depends on the continuous evaluations of genotypes obtained in breeding programs. The purpose of this work was to evaluate the reaction of the crossing of Icatu or Catuaí with Timor Hybrid or Catimor progenies against one population o...
