Resumo: | The objective of this study was to evaluate yield, adaptability, and stability of sugarcane genotypes using the harmonic mean of relative performance of genotypic values method (MHPRVG), and to compare it with the method of differences of the segmented straight line weighted by the residual coefficient of variation (DRRB-CV), based on the Pi statistic from Linn & Binns. Employing the augmented block design, with five blocks, seventy clones and two checks were evaluated. Two experiments were carried out in each of seven environments in Minas Gerais State. Evaluations were performed in plant and ratoon. Considering the selection for sugar yield, adaptability, and stability, three clones performed better: RB947520, RB957712, and P86-42. The MHPRVG method was highly correlated with the parameters of the DRRB-CV method, and with the genotypic values that took into account the genotype x environment mean interaction. All the correlations between these statistical measurements were greater than 0.90. However, the MHPRVG method has the advantage that the results appear on the same scale of the characters evaluated, which could be directly interpreted as genetic values. Another advantage for clone selection is that this method takes into consideration simultaneously the criteria yield, adaptability, and stability. KEY-WORDS: Mixed models, REML/BLUP, stability, MHPRVG method. |

O presente trabalho teve como principal objetivo avaliar a produtividade, adaptabilidade e estabilidade de genótipos de cana-de-açúcar utilizando o método da média harmônica da performance relativa dos valores genotípicos (MHPRVG), bem como compará-lo com a metodologia das diferenças em relação à reta bissegmentada ponderadas pelo coeficiente de variação residual (DRRB-CV), baseada na estatística Pi de Lin & Binns. Utilizando-se o delineamento de blocos aumentados com cinco blocos, setenta clones e duas testemunhas foram avaliados em sete ambientes representativos das regiões produtoras de cana-de-açúcar de Minas Gerais. Em cada ambiente foram instalados dois experimentos. As avaliações foram realizadas em cana-planta e soqueira. Considerando a seleção para produtividade de açúcar por hectare, adaptabilidade e estabilidade três clones se destacaram: RB947520, RB957712 e SP86-42. O método MHPRVG mostrou-se altamente correlacionado com os parâmetros da metodologia DRRB-CV e com os valores genotípicos que capitalizam a interação genótipo x ambiente média. As correlações entre essas estatísticas foram superiores a 0,90. Contudo, o método MHPRVG, em relação à estatística Pi, apresenta a vantagem de fornecer resultados na própria escala de medição do caráter avaliado, os quais podem ser interpretados diretamente como valores genéticos. Outra vantagem para seleção de clones é que o MHPRVG contempla simultaneamente os critérios produtividade, adaptabilidade e estabilidade.
