Abstract

In the world scenario, coffee culture is among the most commercialized and profitable products, representing a source of income for several countries. The species Coffea canephora L. stands out in coffee growing in Brazil, having great importance for the economy in its contribution as a positive acting agent in the Brazilian trade balance. Given this economic importance, the aim of the project is to evaluate the behavior of 20 Coffea canephora coffee clones in the Ribeira Paulista Valley, combined with good agronomic characteristics, in order to generate information that contributes to the technical recommendation of these cultivars for the region. The experiment was installed in December 2018, at the Experimental Campus of the São Paulo State University "Júlio de Mesquita Filho" - UNESP, in Registro-SP, with a spacing of 3.00 x 1.0m. The experimental design used is randomized blocks, with three replications, and plots of 10 plants, with only six central plants being considered as a useful plot. The following characteristics will be evaluated: stem diameter, number of plagiotropic branches, plant height, number of plagiotropic branches, length of plagiotropic branch, incidence of cercosporiosis in coffee leaves, incidence and severity of rust, incidence of miner bug on the leaves of coffee trees and incidence of phoma. Statistical analyzes will be performed using the computer program Sisvar (Ferreira 2000). The genotypic and phenotypic correlations between all evaluated traits will also be estimated, using the Selegen-REML / BLUP program (Resende, 2007). The average data, of the evaluated characteristics, will be submitted to the analysis of variance by the F test and the means compared by the Skott Knott test at 5% probability. At the end of the work, it is expected to generate information that contributes to the technical recommendation of these clones for the Vale do Ribeira Paulista region.
