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 GGE Biplot for integrating agronomic and sensory attributes in coffee cultivar selection(Crop Breeding and Applied Biotechnology, 2025-07-16) Reis, Antônio Augusto Rezende; Botelho, Cesar Elias; Nadaleti, Denis Henrique Silva; Figueiredo, Otávio José de; Botelho, Thiago Tavares; Gonçalves, Flavia Maria Avelar; Carvalho, Alex Mendonca; Andrade, Vinicius Teixeira; Figueiredo, Vanessa Castro; Abrahão, Juliana Costa de RezendeCoffee plant breeding has developed cultivars with disease resistance, high yield, and excellent sensory quality. However, recommending cultivars for different regions requires evaluations that account for genotype × environment (G × E) interactions. This study evaluated the agronomic performance of 30 Coffea arabica cultivars in six locations in southern Minas Gerais, focusing on adaptability and phenotypic stability for yield and sensory quality using the GGE Biplot method. Traits assessed included yield, the proportion of high-sieve and mocha beans, bean density, and sensory quality. Statistical analyses involved ANOVA, the Scott-Knott test, and GGE Biplot. Two mega-environments were identified for yield and three for sensory quality. IPR 100, IAC Obatã 4739, Arara, and Catucaí 2SL demonstrated high yield, while MGS Paraíso 2 excelled in cup quality. GGE Biplot proved effective in identifying stable and adapted cultivars, reinforcing the need to integrate sensory attributes in breeding and recommendation strategies for specialty coffee production.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 New and efficient AS-PCR molecular marker for selection of coffee resistant to coffee leaf rust(Crop Breeding and Applied Biotechnology, 2024-10-15) Almeida, Dênia Pires de; Carneiro, Deisy Guimarães; Caixeta, Eveline Teixeira; Alves, Danúbia Rodrigues; Zambolim, LaércioCoffee leaf rust, caused by Hemileia vastatrix, is the most important disease affecting Coffea arabica. The use of molecular markers through marker-assisted selection (MAS) is an effective approach to develop cultivars with multiple and durable resistance, which is economically and environmentally beneficial for this disease control. In this work, a new molecular marker based on allele-specific polymerase chain reaction (AS-PCR) associated with the quantitative trait locus (QTL) of the linkage group 5 (LG5), which confers resistance to races I, II and pathotype 001 of H. vastatrix, was developed. The CaRHv10-AS marker was validated in a segregating genetic mapping population of 247 F2 genotypes and demonstrated selection efficiency greater than 97% for genotypes with resistance to three races. Thus, this work provides a fast, robust, and affordable molecular marker for use in MAS, facilitating the development of coffee plants with multiple resistance and ensuring sustainable coffee production.Item IPR Pérola: Dwarf Arabica coffee cultivar with high resistance to leaf rust and large beans(Crop Breeding and Applied Biotechnology, 2024-10-04) Sera, Gustavo Hiroshi; Sera, Tumoru; Mariucci Junior, Valdir; Shigueoka, Luciana Harumi; Bortolato, Kawana SilvaIPR Pérola is a Coffea arabica cultivar developed from a cross between IAPAR 59 and Mundo Novo IAC 376-4. It features a dwarf-medium size, high yield, excellent cup quality, a medium-early ripening cycle, and large beans. Additionally, it boasts high resistance to coffee leaf rust.Item New and efficient AS-PCR molecular marker for selection of coffee resistant to coffee leaf rust(Crop Breeding and Applied Biotechnology, 2024-10-15) Almeida, Dênia Pires de; Carneiro, Deisy Guimarães; Caixeta, Eveline Teixeira; Alves, Danúbia Rodrigues; Zambolim, LaércioCoffee leaf rust, caused by Hemileia vastatrix, is the most important disease affecting Coffea arabica.
