-
(Editora UFLA, 2021-11-22)The development of modified hydroponic cultivation has aroused interest and its use has enabled advantages in several crops, but studies for coffee are still scarce. Thus, the objective of this research was to evaluate ...
-
(Universidade Federal de Viçosa, 1995)É evidente a forte redução da participação do café brasileiro na receita de divisas e no comércio internacional, nas últimas décadas. No entanto, o café ainda possui papel relevante na economia nacional, visto que o ... -
(2003)O gênero Coffea é composto por cerca de 80 espécies, que são diplóides (2n=2X=22) e, geralmente auto-incompatíveis, com exceção da espécie mais importante, Coffea arabica L., que é tetraplóide (2n=4X=44) e autofértil. ...
-
(Universidad Nacional de Colombia, 2014)Coffee is a very important crop for the world economy. The commercial coffee production is based on two species, Coffea arabica L. (70%) and C. canephora Pierre (30%). C. arabica is the only allotetraploid (2n=4x=44) ...

(Embrapa Café, 2015)Um sistema de produção é considerado sustentável quando todas as suas etapas atendem a processos socialmente justos, economicamente viáveis e ambientalmente adequados, visando gerar alimentos seguros para a saúde humana, ... -
(Instituto Agronômico (IAC), 2019)Selection of hybrid coffee plants coming from crosses between divergent populations is particularly relevant for the success of breeding programs. This study aimed to outline the best selection strategy in a hybrid population ...
-
(Instituto de Tecnologia do Paraná - Tecpar, 2007-07)The aim of this study was to identify plants of the IAPAR-59 and Tupi IAC 1669-33 coffee cultivars with less defeated resistance genes by the rust races present at IAPAR (Londrina, Paraná State, Brazil) using test-crosses. ...
-
(Sociedade Brasileira de Plantas Medicinais, 2013-08-23)Aiming to contribute to the development of alternative control methods of the coffee leaf miner, Leucoptera coffeella (Guérin-Mèneville & Perrottet, 1842) (Lepidoptera: Lyonetiidae), a search for plants able to produce ...
-
(Crop Breeding and Applied Biotechnology, 2014-06)The aim of this study was to select high-yielding coffee progenies with resistance to coffee leaf rust for the State of Paraná (Brazil). Field experiments in a randomized block design were carried out in Itaguajé and ...
-
(Universidade Federal de Santa Maria, 2015-07)Due to high temperatures, practically all coffee farms in the state of Rondonia are of the C. canephora species. Thus, importing arabica coffee from other states becomes necessary for composition of blends, as well as for ...
-
(Editora UFLA, 2018-07)This study aimed to evaluate different structures of variance-covariance matrices in modeling of productive performance of coffee genotypes over the years, and select hybrids of Coffea arabica using mixed models. A mixed ...
-
(Universidade Federal de Santa Maria, 2018-04)The objective of this research was to quantify the genetic divergence of potential Coffea canephora parents, with the goal of developing progenies that associate the best traits of the Conilon and Robusta botanical varieties ...

(Crop Breeding and Applied Biotechnology, 2014-06)The purpose of this study was to select Coffea arabica progenies for resistance to M. paranaensis in an infested coffee growing area using Henderson’s mixed model methodology. Forty-one genotypes were selected at the Coffee ...
-
(Editora UFLA, 2019-01)Rust is the main disease of coffee. Recently, cercospora leaf spot has grown in importance, intensifying defoliation and decreasing grain yield in Coffea arabica. The Big Coffee VL is a variety of C. arabica, with large ...
-
(Editora UFLA, 2019-04)The objective of this study was to select coffee progenies with better assessment that can result in coffee rust resistant cultivars and better agronomic characteristics than the traditional ones. The essay was performed ...
-
(Universidade Federal de Lavras, 2022-06-09)Recently, the cultivation of Coffea canephora species has expanded as a consequence of climate change effects and emerging markets that use this cof-fee as raw material. To meet such demands of production, it is necessary ...
-
(Crop Breeding and Applied Biotechnology, 2019)In the northern Minas region, the dry-warm climate predisposes coffee plants to the occurrence of leaf miners, mites, cercosporiosis, and leaf scald. Aiming for the development of a cultivar adapted to these conditions, ...
