Abstract
Repeatability coefficients for production traits were estimated using five statistical analyses for nine strawberry cultivars over two growing cycles in Brazil. These analyses were also used to determine the number of harvests required for the selection of cultivars. Regardless of how the data were analysed (first cycle, second cycle, or joint analysis), the number of fruit per plant, yield, and fruit weight were affected by cultivar, harvest, and the interaction between cultivar and harvest. The first cycle showed the highest repeatability coefficients and determination. Estimates of the repeatability were higher using principal components analysis. In conclusion, early and reliable selection, based on phenotypic data for the production traits of the nine cultivars, should be carried out in the first cycle. Analysis of variance are the highest estimates of yield needed to select the best cultivars in the first cycle. To estimate the fruit weight, the character with the highest repeatability, 17 harvests are required for a 95% confidence index.
