This research is related to the performance evaluation of twelve Coffea arabica cultivars in Vale do Ribeira Paulista, in order to generate consistent information for the technical recommendation for cultivation in the region. The experiment was set in February 2018, at the Experimental Campus of the São Paulo State University “Júlio de Mesquita Filho” - UNESP in Registro, SP, Brazil, in a spacing of 3.00x0.60 ...
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.
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...
The 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...
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...
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...
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...
The 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...
In order to investigate the aspects related to the use of selection indexes in Coffea arabica breeding, analytical procedures were used: index based on the sum of ranks of Mulamba and Mock (ISR), index of desired gains of Pesek and Baker (DGI), classic index of Smith and Hazel (CI), base index of Williams (BI), and direct and indirect selection (DIS). Thirty-nine progenies were evaluated in the 4th generation b...
