-
(Crop Breeding and Applied Biotechnology, 2005)This research was carried out to estimate the variability and genetic parameters for the development of cultivars more frost resistant in Coffea arabica progenies, carrying C. liberica var. dewevrei genes. There is genetic ... -
(Crop Breeding and Applied Biotechnology, 2004)In a backcross population of the allotetraploid Coffea arabica L. the loci with diploid-like segregation were predominant, although a few loci with tetrassomic inheritance or distortion of the expected segregation were ...
-
(Crop Breeding and Applied Biotechnology, 2021-11-20)The objectives of this study were to optimize in vitro pollination and fluorescence microscopy procedures to characterize the gametophytic selfincompatibility of Coffea canephora genotypes. For that purpose, 115 in vitro ...
-
(Crop Breeding and Applied Biotechnology, 2023-08-20)IAC Herculândia is a Coffea canephora cultivar multiresistant to Meloidogyne exigua, M. incognita, and M. paranaensis to be used as a rootstock for Coffea arabica cultivars. It is a synthetic cultivar resulting from ...
-
(Crop Breeding and Applied Biotechnology, 2004)The technique of factor analysis in the simultaneous selection of traits and prediction of genetic gains was evaluated in Coffea canephora var. conilon. Fourteen traits in 40 assessed genotypes were evaluated at two sites. ...
-
(Crop Breeding and Applied Biotechnology, 2004)This study aimed to estimate the repeatability coefficient of the grain yield in Coffea canephora by three methods: to quantify the precision of the measurements; to predict the real value of an individual based on n ...
-
(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, 2018)The aim of this study was to identify resistance to bacterial halo blight in Arabica coffee lines carrying Coffea racemosa genes. Eighteen Arabica coffee lines derivative from the genotype C1195-5-6-2, and the cultivars ...
-
(Crop Breeding and Applied Biotechnology, 2022-09-01)MGS Guaiçara e MGS Vereda are resistant to Meloidogyne paranaensis, one of the most aggressive nematode parasites of coffee. MGS Vereda is an early maturation cultivar, whereas MGS Guaiçara has a medium maturation cycle. ...
-
(Crop Breeding and Applied Biotechnology, 2011-09-08)Gains from selection for yield were estimated in Arabica coffee progenies carrying rust-resistance genes. The experiment in augmented block design was installed in Três Pontas, state of Minas Gerais. Three blocks were ...
-
(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, 2002)The genetic diversity of Coffea arabic L. cultivars is relatively narrow and its assessment and increase is important for breeding. Fifty two arbitrary primers were used to evaluate the reproducibility and the influence ...
-
(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, 2010)Thirty-three coffee SSR primers from enriched genomic library with (GT)15 and (AGG)10 repeats were analyzed in 24 coffee tree accessions. Twenty-two primers were polymorphic among accessions; the number of alleles ranged ...
-
(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, 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, 2004-03-12)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, 2008-10-09)Simple sequence repeat (microsatellite) loci in coffee were identified in clones isolated from enriched and random genomic libraries. It was shown that coffee is a plant species with low microsatellite frequency. However, ...
-
(Crop Breeding and Applied Biotechnology, 2008-06-09)The purpose of this study was to verify the possibility of using direct selection in nine traits underlying indirect selection for yield and determine which traits should participate in the selection process. Data of 40 ...
-
(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 ...
