Crop yield bienniality in groups of genotypes of conilon coffee

Abstract

Coffee plantations present large spatial and temporal variability of yield, the variation along the years with high and low productions is known as bienniality. This study investigated the bienniality in different groups of genotypes of conilon coffee, classified by the ripening cycle, evaluating the crop yield of the clones along four years to determine the magnitude of the bienniality. The results indicate that, the bienniality is present in genotypes of conilon coffee from all the studied groups of genotypes, existing very biennial genotypes and also very stable genotypes within each group.
