ABSTRACT:      The development of superior hybrid cultivars depends on the identification of lines with greater combining ability. This  study  compared  the  discrimination  and  combining  ability  of  four  testers  when  crossed  with  43  partially  endogamous  S3popcorn  (Zea  mays  L.  var.  everta)  progenies  by  the  Residual  or  Restricted  Maximum  Likelihood  and  Best  Linear  Unbiased  Prediction  (REML/BLUP)  approach.  Yield  and  morphological  components  of  genotypes  were  evaluated.  The  experiment  was  arranged in a complete block design with three replicates at two locations (in the North and Northwestern regions of the State of Rio de Janeiro, Brazil). The REML/BLUP approach was able to efficiently discriminate and estimate the combining abilities for all traits assessed. Testers BRS-Angela and P2 had positive effects on all yield components, indicating their suitability as potential parents  of  hybrids  in  crosses  with  S3  progenies.  The  negative  genotypic  effects  were  the  highest  for  the  testers  IAC  125  and  UENF 14, indicating that they could be used to adequately identify the progenies with the highest potential among the evaluated genotypes. Overall, at both locations, tester IAC 125 was the best discriminator of the relative merits of S3 progenies, while BRS-Angela was the tester with the best hybrid yield.

RESUMO:      O desenvolvimento de cultivares híbridas superiores depende da identificação de linhagens com maior capacidade de combinação. Este estudo comparou a discriminação e a capacidade de combinação de quatro testadores quando cruzados com 43 progênies de pipoca S3 parcialmente endógamas (Zea mays L. var. everta) pela abordagem de Máxima Verossimilhança Residual ou Restrita e Melhor Previsão Imparcial Linear (REML/BLUP). O rendimento e os componentes morfológicos dos genótipos foram avaliados. O experimento foi organizado em um delineamento de blocos completo, com três repetições, em dois locais (nas regiões Norte e Noroeste do Estado do Rio de Janeiro, Brasil). A abordagem REML/BLUP foi capaz de discriminar e estimar eficientemente as capacidades de combinação de todas as características avaliadas. Os testadores BRS-Angela e P2 tiveram efeitos positivos em todos os componentes de rendimento, indicando sua adequação como potenciais genitores de híbridos em cruzamentos com as progênies S3. Os efeitos genotípicos negativos foram mais altos para os testadores IAC 125 e UENF 14, indicando que eles poderiam ser usados para identificar adequadamente as progênies com maior potencial entre os genótipos avaliados. No geral, em ambos os locais, o testador IAC 125 foi o melhor discriminador dos méritos relativos das progênies S3, enquanto BRS-Angela foi o testador com o melhor rendimento híbrido.
