          Abstract

          O desempenho de linhagens promissoras de arroz, gerado pelo programa de melhoramento genético do Instituto Agronômico (IAC) foi avaliado em diferentes ambientes. Os ensaios foram instalados em blocos casualizados com quatro repetições e parcelas experimentais com área útil de 6 m² nos anos agrícolas de 2006/2007, 2007/2008, 2008/2009 e 2009/2010, nos municípios de Capão Bonito-SP e Mococa-SP. A variação total dos dados de produção de grãos foi analisada pela ANAVA e pela ANADEV, e foram estimadas as significâncias dos efeitos da interação genótipo x ambiente pelas duas metodologias. A adaptabilidade e estabilidade de 16 genótipos de arroz de terras altas em 8 ambientes foram avaliadas pelos métodos de Eberhart e Russell (1966) e Lin e Binns (1988) e pela metodologia dos modelos mistos (REML/BLUP). Pelo método da média harmônica da performance relativa dos valores genotípicos (MHPRVG) foram selecionadas as linhagens IAC 2009, IAC 1829 e IAC 2005 com produções superiores em 11; 10 e 6% respectivamente, em relação à média geral, o que foi coincidente com os resultados obtidos pelas outras metodologias.

          The performance of promising strains of rice, generated through the genetic improvement program of the Instituto Agronômico (IAC), was evaluated for different environments. The experiments were set up in a randomized-block design with four replications, using experimental plots of 6m², during the periods 2006/2007, 2007/2008, 2008/2009 and 2009/2010, in the municipalities of de Capão Bonito and Mococa, both in São Paulo. The total variation of the data for grain-production was analyzed using ANAVA and ANADEV, and the significance of the effects of the interaction between genotype and environment were estimated for the two methodologies. The adaptability and stability of 16 genotypes of upland rice in eight environments were evaluated using the methods of Eberhart and Russell (1966), Lin and Binns (1988), and mixed-model (REML / BLUP). Using the harmonic mean of the relative performance of genotypic values (MHPRVG), the strains, IAC 2009, IAC 1829 and IAC 2005 were selected, with yields superior to 11; 10 and 6% respectively when compared to the general average, which matched results obtained by other methods.
