Resumo: Open land, called cerrado, almost occupies one fourth of Brazilian territory and is characterized by acid soils with high aluminum saturation. The productivity of non-naturalized plants is reduced since growth of roots is greatly restrained. The use of aluminum-tolerant genotypes together with liming is a very promising strategy for the agricultural use of open land. Knowledge of inheritance mechanisms of aluminum-tolerance contributes towards obtaining of tolerant and productive genotypes. The aim of this research was to investigate the hypothesis of maternal effect on aluminum tolerance of maize inbred lines. Seedlings from six pairs of reciprocal crosses, produced by two tolerant and three non-tolerant inbred lines, were evaluated. Seminal root growth rates in presence of aluminum were similar among all progenies derived by reciprocal crosses. The results demonstrated the control of aluminum tolerance by dominant nuclear alleles in maize, without any detectable effect of extranuclear genes.

O uso de genótipos tolerantes ao alumínio, em combinação com calagem, é uma estratégia promissora para a exploração agrícola dos cerrados. O conhecimento dos mecanismos de herança da tolerância ao alumínio contribuirá para a obtenção de genótipos tolerantes e produtivos. O objetivo deste trabalho foi determinar se há efeito materno na resposta ao alumínio em cruzamentos recíprocos de linhagens endogâmicas de milho. Foram utilizados seis pares de cruzamentos recíprocos entre duas linhagens tolerantes e três sensíveis. Os cruzamentos recíprocos mostraram taxas de crescimento similares na presença de alumínio, evidenciando o envolvimento de alelos dominantes de loci nucleares na determinação da tolerância, sem influência detectável de genes extranucleares.Universidade Estadual De Maringá2008-05-09info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttp://www.periodicos.uem.br/ojs/index.php/ActaSciBiolSci/article/view/281610.4025/actascibiolsci.v22i0.2816Acta Scientiarum.
