Summary: The objective of this work was to evaluate the reaction of maize hybrids of Programa Milho®, obtained from crosses between commercial cultivars to P. polysora, on so il with different levels of phosphorus at Estação Experimental the Gurupi, Brazil, Federal University of Tocantins. In conclusion: variability was observed about the reaction of genotypes in relation to P. Polysora, suggesting that there are sources of resistance for the genetic control of this disease; high input, when compared with low input, increased the incidence of P. polysora in any stages the plant development.

Ambientes e genótipos diferiram quanto à severidade da doença, tanto aos 30 quanto aos 40 DAF. Concluiu-se que a grande variabilidade dos genótipos de milho, quanto à reação a P. polysora, indica que existem fontes de resistência para o controle genético desta doença; Doses elevadas, quando comparadas a doses baixas de fósforo, promovem aumento da incidência do fungo P. polysora em qualquer que seja o estádio de desenvolvimento.Departamento de Diagnóstico e Pesquisa Agropecuária.
