Abstract

On the world stage, 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 objective of the project is to evaluate the reproductive and phytosanitary performance of 20 Coffea canephora coffee clones in the Ribeira Paulista Valley, together with good agronomic characteristics, in order to generate information that contributes to the technical recommendation of these clones 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 that of randomized blocks, with three replications, and plots of 10 plants, with eight central plants being considered as a useful plot. The following characteristics will be evaluated: productivity; percentage of chochos, cherries, green and dried fruits; vegetative vigor; incidence of cercosporiosis in the leaves of coffee trees; rust incidence and severity; incidence of miner bug and incidence of phoma. Statistical analyzes will be performed using the computer program Sisvar (Ferreira 2000). The average data of the evaluated characteristics will be subjected to 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 clones for the Vale do Ribeira Paulista region. (AU)
