Agronomic characterization and responses to coffeeleaf rust in coffee progenies...
Rezende, Ramiro Machado; Carvalho, Gladyston Rodrigues; Carvalho, Alex Mendonça de; Mendes, Antonio Nazareno; Salgado, Sônia Maria LimaThe aim of this study was to determine agronomic characteristics and responses to the coffee leaf rust fungus (Hemileia vastatrix Berk. et Br.) in coffee progenies resistant to the gall nematode Meloidogyne exigua. The experiment was conducted in December 2000 at Ouro Verde Farm (FazendaOuro Verde), located in the municipality of Campos Altos – Minas Gerais (MG). Ten F3:4 progenies were evaluated. They were der...
Phenotypic characterization of Coffea arabica genotypes in infested area by nem...
Carvalho, Alex Mendonça; Salgado, Sonia Lima; Mendes, Antonio Nazareno; Pereira, Antonio Alves; Botelho, Cesar Elias; Tassone, Guilherme AugustoThe Meloidogyne paranaensis causes serious damage to the root system of coffee; it could cause poor vegetative and reproductive development culminating in the death of plants. This trial was carried out aimed to evaluate, in naturally infested by M. paranaensis, vegetative growth, production in the first two years (2011/2012) and the population of the M. paranaensis in genotypes (GEN) Timor Hybrid UFV 408-01 pl...
Progenies selection F4 from icatu and catuaí amarelo crossing with resistance t...
Cardoso, Diego Abreu; Mendes, Antonio Nazareno; Carvalho, Alex Mendonça; Lima, Amador Eduardo; Botelho, Cesar Elias; Carvalho, Gladyston RodriguesWe aimed at evaluate and select coffee tree progenies in F4 generation in order to obtain rust resistant cultivars and agronomic characteristics superior to traditional cultivars. This research was carried out with 33 progenies resulted from crossing of Icatu cultivars and Catuaí Amarelo IAC 62, IAC 17 and the progenies IAC 5002 and IAC 5010; and three susceptible controls. The experimental design used was a ra...
Selection of coffee progenies of catucaí group
Carvalho, Alex Mendonça; Mendes, Antonio Nazareno; Rezende, Fernando Valaci; Botelho, Cesar Elias; Carvalho, Gladyston RodriguesThe coffee tree genetic improvement has brought expressive profit to the activity through the use of cultivars with high productivity and favorable agronomic traits. The aim of the improvement programs is gatheningthe best characters in a cultivar. So it searched to select the coffee tree progenies for favorable characteristics of productivity, grains size, vegetative force, resistance to rust and cercospora le...
