Clonal selection in S0 and S1 peach trees evaluated in a subtropical environment

Abstract The aims of this study were to estimate genetic parameters, predict genotypic values, and analyze the divergence in S0 S1 peach trees evaluated a subtropical environment by mixed model methodology. For this, twenty-two clones for plant fruit traits. Genotypic variance among was significant. individual broad-sense heritabilities ranged from 0.11 0.84, repeatability coefficients 0.15 0.89. variation higher than 10% most Clustering based on traits led formation two five mutually exclusive groups, respectively. Multivariate analysis principal components indicated that some could be excluded evaluation. Considering yield trait selection clones, predicted gain 70%, which shows possibility considerable progress clonal trees.
