Interspecific variability for aluminum tolerance has been described in many species. However, results from studies on transmission of this trait are conflicting because they indicate monogenic and quantitative inheritance, prevalently with the expression of more than one locus. The aim of this research was to evaluate the inheritance of tolerance in a family of maize (Zea mays L.) consisting of aluminum-tolerant and aluminum-sensitive parental inbred lines, and their progenies. Net Seminal Root Lengh (NSRL )was analyzed in seedlings grown in nutrient solution containing 4.5 Ug/mL aluminum. NSRL distributions in F2 and in backcrosses with the aluminum-sensitive parent were bimodal and indicated ratios 3:1 and 1:1 respectively. It is concluted that, in this family, tolerance is inherited as a single trait with a main locus effect.  aMilho  aAluminum toxicity  aAnálise genética  aGenetics of tolerance  aTolerância  aZea mays L1 aSCAPIM, C.
