Item MGS Turmalina: A short rust-resistant Arabica coffee cultivar with drought tolerance and superior beverage quality(Crop Breeding and Applied Biotechnology, 2025-07-15) Oliveira, Antônio Carlos Baião de; Pereira, Antônio Alves; Abrahão, Juliana Costa de Rezende; Ferreira, André Dominghetti; Botelho, Cesar Elias; Nadaleti, Denis Henrique Silva; Caixeta, Eveline Teixeira; Gonçalves, Flavia Maria Avelar; Carvalho, Gladyston Rodrigues; Salgado, Sonia Maria Lima; Silva, Vania Aparecida; Figueiredo, Vanessa Castro; Andrade, Vinicius TeixeiraThe MGS Turmalina coffee cultivar is short in size, matures early, and is rust resistant. It has demonstrated a higher yield than the Catuaí Vermelho IAC 99 cultivar in different regions, standing out in environments with greater water deficit. The market value of MGS Turmalina beans is higher due to its superior cup quality.Item Agronomic performance and beverage quality of the arabica coffee cultivar MGS Catucaí Pioneira(Crop Breeding and Applied Biotechnology, 2025-10-18) Botelho, César Elias; Abrahão, Juliana Costa de Rezende; Nadaleti, Denis Henrique Silva; Ferreira, André Dominghetti; Pereira, Antônio Alves; Oliveira, Antônio Carlos Baião de; Gonçalves, Flávia Maria Avelar; Carvalho, Gladyston Rodrigues; Malta, Marcelo Ribeiro; Andrade, Vinicius Teixeira; Figueiredo, Vanessa CastroThe MGS Catucaí Pioneira cultivar stands out for its yield, rust resistance, and beverage quality. Evaluated over four harvest seasons in ten municipalities of southern Minas Gerais, it demonstrated excellent agronomic performance and a sensory profile with floral and sweet notes, making it suitable for both mechanized and non-mechanized production systems.Item Coverage plants in coffee production systems as weed control(Universidade Federal de Lavras, 2024-05-02) Barros, Vanessa Maria de Souza; Thimothee, Jean Alex; Rodrigues, Rafael Jorge Almeida; Gonçalves, Adenilson Henrique; Medeiros, Fernanda Carvalho Lopes de; Ferreira, André Dominghetti; Carvalho, Gladyston RodriguesThe aim of this study was to evaluate the floristic and phytosociological compositions of weeds and the influence of cover crops between rows of organic and conventional coffee plantations. The assessment of weeds was carried out in two seasons (dry and rainy) in 2019 and 2020. A square made from welded iron bars of 0.50 x 0.50 m (0.25 m2) was launched four times in each block randomly, avoiding overlap, totaling 4.0 m2 of sampled area. A total of 41 weed species were found and described, which were distributed in 38 genera and 19 families with the predominance of Poaceae and Asteraceae. The most abundant species were Cyperus sp. and Urochloa decumbens Staf. that occurred simultaneously in all treatments and showed greater importance (IVI) among weeds. The similarity index is generally low, indicating that the weed community was affected by the presence and absence of cover crops.Item MGS Guaiçara and MGS Vereda: Coffea arabica cultivars resistant to the root-knot nematode Meloidogyne paranaensis(Crop Breeding and Applied Biotechnology, 2022-09-01) Salgado, Sônia Maria de Lima; Fatobene, Bárbhara Joana dos Reis; Pereira, Antonio Alves; Abrahão, Juliana Costa de Rezende; Botelho, Cesar Elias; Carvalho, Gladyston Rodrigues; Oliveira, Antônio Carlos Baião de; Ferreira, André Dominghetti; Figueiredo, Vanessa Castro; Vilela, Diego Junior Martins; Luz, Silvana Ramlow Otto Teixeira da; Andrade, Vinicius TeixeiraMGS Guaiçara e MGS Vereda are resistant to Meloidogyne paranaensis, one of the most aggressive nematode parasites of coffee.

The MGS Aranãs cultivar is characterized by small size, ripe red fruits, large seeds, coffee leaf rust resistance, an architecture suitable for densification, production stability, and high beverage quality. This new cultivar is recommended for the Sul de Minas, Cerrado Mineiro and Vale do Jequitinhonha regions.Item Nutritional efficiency in phosphorus of arabica coffee genotypes(Editora UFLA, 2021) Vilela, Diego Júnior Martins; Coelho, Larissa Sousa; Silva, Douglas Ramos Guelfi; Carvalho, Gladyston Rodrigues; Botelho, Cesar Elias; Ferreira, André DominghettiNutritional efficiency is a term used to characterize plants in their capacity to uptake and use nutrients, being related to the efficiency of uptake, translocation, and utilization of nutrients. Different coffee genotypes are expected to exhibit variability in their nutritional efficiency. This work aimed to evaluate the phosphorus nutritional efficiency in arabica coffee genotypes. The experiment was carried out in a greenhouse of the Empresa de Pesquisa Agropecuária de Minas Gerais (EPAMIG), located in the municipality of Lavras – Minas Gerais, Brazil. The experimental design was a randomized complete block design, in a 10x2 factorial scheme (10 arabica coffee genotypes and two dosages of phosphate fertilization), with four replicates. Each experimental plot consisted of one pot with ten liters of soil, with one plant. The cultivars Catiguá MG2, MGS Ametista and Sarchimor MG 8840 are neither efficient nor responsive to phosphate fertilization. Progeny H 6-47-10 pl. 3 and the cultivar Catuaí Vermelho IAC 144 are not efficient but are responsive to phosphate fertilization. The cultivars Paraíso MG H 419-1, Topázio MG 1190 and MGS Paraíso 2 are efficient but are not responsive to phosphate fertilization. The cultivars Bourbon Amarelo IAC J10 and MGS Aranãs are efficient and responsive to phosphate fertilization.Item Selection of coffee progênies for resistance to leaf rust and favorable agronomic traits(Editora UFLA, 2019-04) Dias, Rafael Almeida; Ribeiro, Marcelo Resende; Carvalho, Alex Mendonça de; Botelho, Cesar Elias; Mendes, Antonio Nazareno Guimarães; Ferreira, André Dominghetti; Fernandes, Fernando CostaThe 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 at the EPAMIG experimental field in Patrocínio, state of Minas Gerais, Brazil. Twenty-five progenies in the F 3 generation were studied. The experiment was set in a randomized complete block design with three replicates and ten plants per plot, arranged in rows at 3.5x0.7m. Productivity assessment, fruit production, in liters of “farm coffee” per plot, bean rating in a sieve (16 or above), and plant vigor were accessed in three different harvest seasons (2011/2012 harvest to 2014/2015 harvest), and coffee rust incidence and severity were then evaluated for 2016. The production profit estimation through the selection was also assessed, by the gain of direct selection for each characteristic, when compared to the rank addition. Progenies 13 (Icatu V. IAC 4040 x IAC 5002) and 3 (Icatu A. IAC 2944 x IAC 5002) were promising in generation advance, for being among the five most productive progenies. The selection gain reached by direct selection was superior than the gain of the total rank additions.
