Response of Conilon coffee cultivars in the central cerrado in irrigated management pivot sprinkler

Coffee cultivation has been growing significantly, since the world demand increased considerably in recent decades. Among coffees, conilon coffee a good option for Cerrado, as it presents production areas of high altitudes, however study canefora irrigated system Cerrado is something recent. The work aimed to analyze productive potential superior clones caneflower cultivars through agronomic performance under conditions Central and select outstanding future use genetic improvement programs. experiment was conducted experimental area Embrapa Cerrados Planaltina - DF, randomized block design with three replications. evaluated were Diamante ES 8112, 8122 Jequitibá Centenária 8132, each composed 9 totaling 27 genotypes, different maturation times. planted 3.5 x 0.5 m spacing center pivot irrigation system. characteristics from two harvests (2018 2020) were: average grain yield (PMG); percentage grains retained sieve 16 (sieve > 16); mocha (GMO); plant height (AP), crown projection (PC) number nodes (NNP). Data submitted analysis variance means grouped by Scott-Knott test at 5% significance level. Based on result variance, there significant difference all cycles traits PMG, 16, GMO, AP, PC NNP. averages size or larger distinct 3 groups analyzed. It found that processed (PMG) years evaluated, due environmental imposed one year another. Within clones, clone 207 presented highest value 2020 12493 kg ha-1. There genotypic variability behavior clonal varieties their respective being able them within breeding programs, targeted crosses subsequent development new cultivars.
