SELEÇÃO DE CULTIVARES DE CAFEEIROS ARÁBICA ADAPTADOS E PRODUTIVOS NAS CONDIÇÕES DO SUL DO ESTADO DE GOIÁS

Abstract

Coffee is one of the most appreciated and consumed drinks in the world and Brazil stands out as the world's largest producer and exporter of this product. There is great genetic diversity in the Coffea genus produced in Brazil, with the possibility of selecting new cultivars. The State of Goiás is still incipient in coffee production, but the selection of genotypes that adapt to soil and climate conditions can contribute to increasing cultivation possibilities. Therefore, the present study aimed to evaluate the adaptability and productivity of Coffea arabica genotypes in the climatic conditions of the South of the State of Goiás. The experiment was installed and conducted at the Instituto Federal Goiano - Campus Morrinhos since 2011. Seedlings of 25 Arabica coffee varieties, where 9 genotypes have not adapted to local conditions and 16 are still under study. The last harvest analyzed was carried out in June and July 2022. This was done manually, when most of the fruits were ripe, at the cherry stage. Fruit production was evaluated in kilograms of coffee (“roça coffee”) per plot. Treatment means were compared using the Scott-knott test at a 5% significance level. Based on production data from the tenth harvest, it can be concluded that the cultivars, Mundo Novo IAC 379/19, H-518-3-6-462-M and Mundo novo Machado in the 2021/2022 harvest presented the best results of productivity, so that they can be recommended for cultivation in the southern region of Goiás
