          Abstract

          O presente trabalho teve por objetivo estimar a estabilidade e a adaptabilidade de oito genótipos de amendoim ereto e comparar os modelos de análise de EBERHART & RUSSELL (1966), WRICKE (1965) e LIN & BINNS (1988), baseando-se em dados de produtividade de vagens e sementes. Os genótipos de amendoim foram avaliados em 14 ambientes situados nas Regiões Nordeste e Centro-Oeste, durante os anos de 2006 a 2011, sob o delineamento de blocos ao acaso com cinco repetições. Verificou-se que, entre os três métodos estudados, os de EBERHART & RUSSELL(1966) e LIN & BINNS (1988) geraram informações concordantes para estimativas de adaptação e estabilidade de produção de vagens e sementes, baseando-se nas condições deste estudo. Os genótipos L7 Bege e BRS 151 L7 foram os mais produtivos, com adaptabilidade específica a ambientes favoráveis, enquanto que CNPA 280 revelou adaptabilidade ampla e alta estabilidade fenotípica.

          This study aimed to estimate the stability and adaptability parameters in upright-peanut genotypes, based on pod and seed yield, through EBERHART & RUSSELL (1966), WRICKE (1965) and LIN & BINNS (1988) methodologies. The genotypes were evaluated in 14 environments located in Northeast and Midwest regions, during 2006 to 2011, in a randomized blocks design, with five replications. EBERHART & RUSSELL (1966) and LIN & BINNS (1988) methodologies revealed similar results, identifying genotypes with high adaptability and stability to pod and seed yield. The BRS 151 L7 and L7 Bege were the most productive, revealing specific adaptability to favorable environment, while CNPA 280 AM revealed broad adaptability and high phenotypical stability.
