ABSTRACT - The objective was to identify phenotypic and genotypic associations, and cause-and-effect relations of secondary components on primary components to establish criteria in the indirect selection process for maize. Partial diallel crosses were conducted in levelândia. F1’s were evaluated in five environments. For the purpose of increasing the yield of corn grain, breeders should seek to reduce the characters distance from the last node to the first branch of the tassel, tassel length and number of branches. The indirect selection for distance from the last node to the first branch of the tassel would be effective to increase the grain yield. The selection for smaller leaf angle, larger stem diameter and thousand grain weight are favorable for increasing grain yield in maize.

Key words: direct and indirect effects, Zea mays L., Tassel characters.</abstract>

RESUMO - O objetivo deste trabalho foi identificar associações fenotípicas, genotípicas e relações de causa e efeito de componentes secundários sobre componentes primários para se estabelecer critérios nos processos de seleção indireta para milho. Os cruzamentos do dialelo parcial foram conduzidos em Clevelândia. Os F1’s foram avaliados em cinco ambientes. Para fins de aumento do rendimento de grãos de milho, os melhoristas devem buscar a redução dos caracteres distância do último nó até primeira ramificação do pendão, comprimento do pendão e número de ramificações. A seleção indireta para menor distância do último nó até a primeira ramificação do pendão seria eficiente para o aumento do rendimento de grãos. A seleção para menor ângulo de folha, maior diâmetro de colmo e massa de mil grãos mostram-se favoráveis para o aumento do rendimento de grãos em milho.

Palavras-chave: efeitos diretos e indiretos, Zea mays L., Caracteres de pendão.</abstract>
