No. of bitstreams: 0 Previous issue date: 2021-01-12; Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq); Fundação de Amparo à Pesquisa do Estado de Minas Gerais (FAPEMIG); The evaluation of coffee quality in Brazil for commercialization is conducted mainly through sensory analysis, also known as the cup test, in which professional taster...

MG Travessia: a coffee arabica cultivar productive and responsive to pruning

This paper presents the results of progeny 1190-1170-2, which was recorded as ‘MGS Travessia’ and selected based on its performance in the state of Minas Gerais. The cultivar has short size, cylindrical canopy, high yield capacity, high vegetative vigor, very satisfactory husk/bean ratio, grain quality compatible to traditional cultivars, and is very responsive to skeleton pruning.

Agronomic characterization and responses to coffeeleaf rust in coffee progenies...

The 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...

Progenies selection F4 from icatu and catuaí amarelo crossing with resistance t...

We 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...

Behavior of coffee cultivars under the incidence of diseases of rust and gray l...

Orange rust, caused by Hemileia vastatrix, is the main coffee disease in terms of scope and damage. The development of cultivars, resistant and/or tolerant to pests and diseases, has an important role in the productivity increase and production cost decrease. Thus, the aim of this study was to provide information about the reaction of ten commercial cultivars of C. Arabica to the incidence of rust and gray leaf...

Adaptability and phenotypic stability of F4 progenies of Coffea arabica l.

The search for new genotypes with broad stability and adaptability, allied to good agronomic traits has been the main focus of coffee breeding programs in Brazil. With this work, we aimed at selecting C. arabica progenies, related to phenotypic adaptability and stability, to identify the genotypes with best behavior concerning environmental changes. The trial was installed in January of 2007, in the Experimenta...

Initial growth of coffee tree cultivars with different doses of nitrogen, phosp...

The mineral nutrition of the coffee tree is very important for its yield, and several places that previously were considered unfit for the cultivation, today exhibit highly productive crops, where soil fertility correction, over time, combined with proper mineral nutrition, are some of the main factors for this success. The aim of this research was to evaluate four new coffee cultivars at initial growth under d...

Agronomic performance of ‘Bourbon’s’ group coffee plants populations

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...

Recovery of coffee cultivars under the ‘skeleton cut’ pruning after 4.5 years o...

In view of the adverse weather in the last years as well as the intensification of pruning in new crops, it evaluated the vegetative and reproductive resilience after pruning type ‘skeleton cut’ in 24 commercial cultivars of C. arabica crop in 4.5 years of age. At 24 months after the pruning, the agronomic characteristics were evaluated by yield, floating grains percentage, bean size and vegetative vigor of the...
