The coffee breeding research influences directly to the obtainment of coffee trees more productive. The purpose of this study was to evaluate the agronomic characteristics of the Bourbon coffee group plants, in two coffee growing regions of Minas Gerais state, aiming at the populations selection with high productivity, adapted and stable. In experiment consisting of 20 treatments were evaluated 17 populations o...
The cities in the South of Minas Gerais, which is the main coffee producer region in Brazil, would face a serious risk of productivity loss if more aggressive root-knot nematodes species, such as Meloidogyne paranaensis. In order to prevent the dissemination of this nematode, it is necessary to know the occurrence outbreaks and distribution of Meloidogyne spp. in this region. Then, objective was to investigate ...
The use of genetic materials Coffea sp. resistance to M. paranaensis with good agronomic performance can able to maintain coffee production activities in infested areas. The aim of this research was characterize the agronomic performance of coffee progenies and the reaction to M. paranaensis. The trial was carried out at Guaiçara farm located in the city of Piumhi- MG in February 2012. 21 progenies of F5 genera...
The 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...
This work aimed to develop embryos and acclimatize seedlings of Coffea arabica L. cv. Rubi produced by direct somatic embryogenesis. For the development of somatic embryos, were evaluated the effect of sucrose (0; 15; 30; 45 and 60 g.L-1) and GA3 (0; 2.5; 5 and 10 mg.L-1). For the development of seedlings, were evaluated the influence of GA3 (0; 2.5; 5; 10 mg.L-¹) and NAA (0; 0.25; 0.5; 1; 2 mg L-¹). ...
The objective of this work was to evaluate the productivity and resistance to leaf rust (Hemileia vastatrix Berk. & Br.) of twenty four F4 coffee progenies from crosses between the Icatu and Catimor cultivars. The experiment was carried out in Três Pontas, Minas Gerais State, in a randomized block design with four repetitions and 25 treatments. The Rubi MG 1192 cultivar was used as control. Coffee bea...
