Item Coffea arabica clones resistant to coffee leaf miner(Crop Breeding and Applied Biotechnology, 2016-03) Guerreiro Filho, Oliveiro; Mendonça, Alex Paulo; Nonato, Juliana Vieira Almeida; Andrade, Vinícius Teixeira; Fatobene, Bárbhara Joana dos Reis; Braghini, Masako Toma; Prela-Pantano, AngelicaBrazilian 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 coffee leaf rust, Hemileia vastatrix. Aiming to reduce the selection process of cultivars with multiple resistances to both biotic constraints, the Coffea arabica clones 760, 1059, 1064 and 1215 were evaluated under field conditions. The mean yield of four C. arabica clones was not statistically different from the experimental controls; however, the yield of clone 1059 was 21% higher than the control cultivar Obatã IAC 1669-20. Leaf miner resistance level in all the evaluated clones remained the same as the mother plant’s. However, the same did not occur for resistance to H. vastatrix, due to the emergence of new pathogen races. In summary, it is potentially feasible the adoption of clone 1059 as a new clonal cultivar resistant to coffee leaf miner.Item IAC 125 RN – A dwarf coffee cultivar resistant to leaf rust and root-knot nematode(Crop Breeding and Applied Biotechnology, 2018-03) Fazuoli, Luiz Carlos; Braghini, Masako Toma; Braghini, Masako Toma; Silvarolla, Maria Bernadete; Gonçalves, Wallace; Mistro, Júlio César; Gallo, Paulo Boller; Guerreiro Filho, OliveiroIAC 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 races of coffee rust, Hemileia vastatrix, present in Brazil. Brazil.Item IAC Catuaí SH3 - a dwarf Arabica coffee cultivar with leaf rust resistance and drought tolerance(Crop Breeding and Applied Biotechnology, 2019) Fazuoli, Luiz Carlos; Braghini, Masako Toma; Silvarolla, Maria Bernadete; Gonçalves, Wallace; Mistro, Júlio César; Gallo, Paulo Boller; Guerreiro Filho, OliveiroThe cultivar IAC Catuaí SH3 was developed by the pedigree method, from the recombination of the coffee tree H 2077-2-5-46, of the Catuaí Vermelho germplasm, with accession IAC 1110-8, from the exotic cultivar BA10. Cultivar IAC Catuaí SH3 is high-yielding, resistant to coffee leaf rust and tolerant to drought.Item IAC Herculândia - a Coffea canephora rootstock multiresistant to Meloidogyne species(Crop Breeding and Applied Biotechnology, 2023-08-20) Guerreiro Filho, Oliveiro; Fazuoli, Luiz Carlos; Braghini, Masako Toma; Gallo, Paulo Boller; Oliveira, Claúdio Marcelo Gonçalves; Padilha, Lilian; Fatobene, Barbhara Joana dos Reis; Andrade, Vinicius Teixeira; Vasconcelos, Larissa de Brito Caixeta; Rosa, Juliana Magrinelli OsórioIAC 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 recombination among the clonal cultivars IAC WG, IAC FEBS, IAC PM, IAC LCCBF, and IAC ARM.Item IAC Herculândia – a Coffea canephora rootstock multiresistant to Meloidogyne species(Crop Breeding and Applied Biotechnology, 2023-08-20) Guerreiro Filho, Oliveiro; Fazuoli, Luiz Carlos; Braghini, Masako Toma; Gallo, Paulo Boller; Oliveira, Claúdio Marcelo Gonçalves; Padilha, Lilian; Fatobene, Bárbhara Joana dos Reis; Andrade, Vinicius Teixeira; Vasconcelos, Larissa de Brito Caixeta; Rosa, Juliana Magrinelli OsórioIAC 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 recombination among the clonal cultivars IAC WG, IAC FEBS, IAC PM, IAC LCCBF, and IAC ARM.Item IAC Obatã 4739 – dwarf arabic coffee cultivar with yellow fruits and resistant to leaf rust(Crop Breeding and Applied Biotechnology, 2018-07) Fazuoli, Luiz Carlos; Braghini, Masako Toma; Silvarolla, Maria Bernadete; Gonçalves, Wallace; Mistro, Júlio César; Gallo, Paulo Boller; Guerreiro Filho, OliveiroCultivar IAC Obatã 4739 was derived from a cross between coffee tree IAC 1669-20-1 and cultivar Catuaí Amarelo IAC 62. It is short and high-yielding, rust-resistant, has large and yellow fruits, medium to late maturation, excellent cup quality, and responds effectively to irrigation.
