ABSTRACT:   This  study  aimed  to  evaluate  the  adaptability  and  yield  stability  of  20  erect/semierect  cowpea  genotypes  in  the  Brazil Mid-North region through three methodologies. The experiments were carried out in 10 environments, corresponding to the Cerrado, Caatinga and Amazon biomes. The research was carried out during the period of 2010 to 2011. The experiments were  arranged  in  a  randomized  block  design,  with  four  replications.  The  Cerrado  biome  and  the  Balsas/MA  region  were  the  most suitable locations for cowpea cultivation, comprising the environments with greater yield stability. Theil (1950) methodology showed low sensitivity in genotype discrimination, while those of Lin & Binns modified by Carneiro and AMMI were more sensitive. For unfavorable environments, Lin & Binns (1998) methodology modified by Carneiro (1998) identified the cultivar BRS Tumucumaque with greater stability, whereas the AMMI methodology identified this cultivar with greater adaptation in favorable environments. Both methodologies identified the MNC02-676F-3 strain with better adaptation to favorable environments. The association of methodologies is necessary to complement the interpretation of the adaptability and stability of cowpea genotypes in the Mid-North of Brazil.

RESUMO:   Este estudo teve como objetivo avaliar a adaptabilidade e estabilidade de produção de 20 genótipos de feijão-caupi de porte ereto/semiereto na região Meio-Norte do Brasil por meio de três metodologias. Os experimentos foram conduzidos em 10 ambientes, correspondentes aos biomas Cerrado, Caatinga e Amazônia. A pesquisa foi conduzida durante o período de 2010 a 2011. Os experimentos foram arranjados em delineamento de blocos casualizados, com quatro repetições. O bioma Cerrado e a região de Balsas/MA foram os locais mais adequados para o cultivo do feijão-caupi, compreendendo os ambientes com maior estabilidade de produção. A metodologia de Theil (1950) mostrou baixa sensibilidade na discriminação de genótipos, enquanto as de Lin & Binns modificadas por Carneiro e AMMI foram mais sensíveis. Para ambientes desfavoráveis, a metodologia de Lin & Binns (1998) modificada por Carneiro (1998) identificou a cultivar BRS Tumucumaque com maior estabilidade, enquanto a metodologia AMMI identificou esta cultivar com maior adaptação em ambientes favoráveis. Ambas as metodologias identificaram a  cepa  MNC02-676F-3  com  melhor  adaptação  a  ambientes  favoráveis.  A  associação  de  metodologias  é  necessária  para  complementar a interpretação da adaptabilidade e estabilidade de genótipos de feijão-caupi no Meio-Norte do Brasi.
