(Crop Breeding and Applied Biotechnology, 2018)The coffee cultivar Catuaí is among the most successful cultivars in Brazilian agriculture; it has been on the market for more than 40 years. It was obtained by Dr. Alcides Carvalho, a researcher of the Instituto Agronômico ... -
(Crop Breeding and Applied Biotechnology, 2020)Amazonian Robustas are ten new clones of high yield potential with characteristics typical of the botanical varieties conilon and robusta. With individual registration, the new cultivars were developed to be grown together ...
-
(Crop Breeding and Applied Biotechnology, 2005-09-06)The root-knot nematode Meloidogyne exigua is a parasite which attacks the Arabica coffee tree (Coffea sp.) and its eradication from infested areas is practically impossible. The wide dissemination of this nematode across ...
-
(Crop Breeding and Applied Biotechnology, 2019)Andina is a conilon coffee variety originated from a selection of clones discovered by farmers. It was cultivated and evaluated for yield and plant vigor an altitude of 850m asl. Five genotypes (A1, NV2, NV8, P1 and Verdim ...
-
(Crop Breeding and Applied Biotechnology, 2023-10-25)The aim of this work was to validate markers linked to the SH3 gene of coffee leaf rust (CLR) resistance and use them in assisted selection. Initially, we validated the markers in genotypes already known to carry SH3. Next, ...

Breeding potential and genetic diversity of “Híbrido do Timor” coffee evaluated by molecular markers(Crop Breeding and Applied Biotechnology, 2010-06-20)AFLP, RAPD and SSR molecular markers were used to study the genetic diversity and genetic structure of the Híbrido de Timor germplasm. The principal coordinate analysis, UPGMA cluster analysis based on genetic dissimilarity ...
-
(Crop Breeding and Applied Biotechnology, 2021)The state of Espírito Santo is the major producer of Coffea canephora in Brazil. Knowledge of genetic reserves is fundamental to plant breeding. Therefore, the present study characterized and analyzed the genetic diversity ...
-
(Crop Breeding and Applied Biotechnology, 2004-03-12)Eighteen clones of differential coffee tree hosts for Hemileia vastatrix Berk. et Br. were characterized with RAPD markers. The genetic distances were estimated and the genealogical origin of the clones compared to data ...
-
(Crop Breeding and Applied Biotechnology, 2005-09-20)The objective of this work was to group different coffee species present in the genebank of the Instituto Agronômico by using some chemical variables. A total of thirty-nine plants belonging to seven species were analyzed ...
-
(Crop Breeding and Applied Biotechnology, 2016-03)Brazilian arabica coffee production is based on a set of highly productive cultivars sexually propagated. All of them are susceptible to coffee leaf miner, Leucoptera coffeella, and most of them are also susceptible to ...
-
(Crop Breeding and Applied Biotechnology, 2001)This paper introduces the coffee genetic breeding research program developed by IAPAR (Agronomic Institute of Paraná, Brazil) which started in 1973. The characteristics of a breeding program for a seed-propagated perennial ...
-
(Crop Breeding and Applied Biotechnology, 2004)Grafted Coffea arabica L. plants were grown hydroponically in a greenhouse for an evaluation of their nutritional efficiency under the influence of different rootstocks. Four C. arabica genotypes were used as scions: ‘Catuaí ...
-
(Crop Breeding and Applied Biotechnology, 2004-07-07)This study evaluated the adequacy of the composition of three clonal Coffea canephora varieties recommended for the State of Espírito Santo by a multivariate method designated discriminant analysis. This method consists ...
-
(Crop Breeding and Applied Biotechnology, 2019-01)This work aimed to study the effective population size and genetic gain in a population of robusta coffee (Coffea canephora Pierre) and verify the possibility of using recurrent selection. The experiment comprised 25 ...
-
(Crop Breeding and Applied Biotechnology, 2007-06-30)Genetic parameters of Arabic coffee progenies derived from the cross Villa Sarchi x Timor hybrid were estimated in order to evaluate their potential for improvement. The experiment was installed in a random block design ...
-
(Crop Breeding and Applied Biotechnology, 2020)Brazilian coffee cultivation was boosted over the last few decades by the mechanization of various field operations. Considering the influence of genetic factors on coffee harvesting efficiency, we aimed to evaluate the ...
-
(Crop Breeding and Applied Biotechnology, 2009)This study aimed to evaluate the genetic variability of 49 Coffea canephora clones of the breeding program of the Capixaba Institute of Research, Technical Assistance and Rural Extension (Incaper) based on RAPD markers. ...
-
(Crop Breeding and Applied Biotechnology, 2002)Cutting propagation of coffee trees has been used for several years in Coffea canephora because of the advantages of this technique compared to seed propagation. Recently, the production of heterotic arabic coffee hybrid ...
-
(Crop Breeding and Applied Biotechnology, 2002)Grafted young coffee trees were observed in a greenhouse to study the effect of different scions and rootstocks on plant growth. Four Coffea arabica L. genotypes were used as scions: the cultivars Catuaí Vermelho IAC 15 ...
-
(Crop Breeding and Applied Biotechnology, 2018-03)IAC 125 RN was derived from a cross between the coffee cultivar Villa Sarchí and the Hibrido de Timor CIFC 832/2. The coffee trees are short and re- sistant to races 1 and 2 of the nematode Meloidogyne exigua and to all ...
