              <text>As populações de milho crioulo são importantes patrimônios genéticos e fontes de genes de tolerância/resistência a estresses que necessitam ser adequadamente caracterizadas quanto ao potencial para o melhoramento. Os objetivos deste trabalho foram determinar o potencial genético individual e em cruzamentos de populações crioulas e identificar materiais para a seleção intrapopulacional e a síntese de compostos em dois locais. Na safra 2000/01, foram avaliadas 31 populações per se, 31 cruzamentos top-crosses intragrupo e dois híbridos em látices 8x8, com cinco e quatro repetições nas cidades de Palmeira e Londrina, Paraná, Brasil, respectivamente. As populações apresentaram comportamento diferenciado nos locais, mas BR 106, Cabo Roxo, Palha Roxa, Ouro Verde e Comum Antigo x Sabugo Fino apresentaram as melhores médias de produtividade em ambos locais, não diferindo estatisticamente das testemunhas (AG1051 e C125). Os efeitos de heterose média foram significativos para produtividade, altura de planta, posição relativa da espiga e porcentagem de acamamento, sem interação com locais. Os cruzamentos produziram cerca de 10,2% (Palmeira) a 8,5% (Londrina) a mais que as mesmas populações per se. As populações Palha Roxa, Milho Sem Nome, Pintado e Comum Antigo x Sabugo Fino apresentaram as maiores estimativas de capacidade geral de combinação para produtividade e participaram das melhores predições de médias para síntese de compostos.Maize landraces are an important genetic patrimony and gene sources of tolerance/resistance to biotic and abiotic stresses, which should be characterized in relation to the breeding potential. The aims of this study were to determine the landraces potential per se and in crosses; to identify genetic materials for intrapopulation selection and composites synthesis in two places. In 2000/01, thirty one populations per se, thirty one top-crosses intragroup and two hibrids were evaluated using an 8x8 lattice, with five and four replications in Palmeira and Londrina, Paraná, Brazil, respectively. The results of the populations per se showed different performances for each local, but BR 106, Cabo Roxo, Palha Roxa, Ouro Verde e Comum Antigo x Sabugo Fino showed higher grain yield means in both places, that did not differ significantly to the means of the commercial checks (AG1051 and C125). The average heterosis effects were significant for grain yield, plant height, ear placement and root lodging percentage, without local interactions. The top-crosses produced 10.2% (Palmeira) and 8.5% (Londrina) more than the same populations per se. The populations Palha Roxa; Milho Sem Nome; Pintado e Comum Antigo x Sabugo Fino showed the highest effects of general combining ability for grain yield and took part in the better composite predictions.</text>
