The environmental variance is quite significant in production and fruits traits, most of quantitative inheritance nature. This study evaluated the effect of years and the determination of the minimum number of necessary years for evaluation one needs for fruit weight, peel weight, length, diameter, relationship length/diameter, pulp revenue and soluble solids contents of fruits of feijoa (Acca sellowiana). Except for soluble solids contents, the effect of years represented great part of the total variance. Based on the repeatability coefficient, it was determined that it would be necessary at least four to six years of evaluation for selection of plants, with accuracy of 80%.
