-This work was conducted at the Universidade Estadual de Londrina (UEL), in Londrina, State of Paraná, Brazil, with the goal to study food-type soybean (Glycine max (L.) Merrill) genotypes performance for use in cultivation or crosses. A total of 104 genotypes were analyzed: 88 were foodtype with large seeds, eight were food-type with small seeds, and eight-grain types adapted cultivars. The experimental plan was in randomized complete block design with four replications, and 12 traits of agronomic importance were considered. Genetic diversity was observed in the food-type germplasm. There were some genotypes with high yield adapted to a normal period of sowing. Soybean genetic improvement programs for direct human consumption in Brazil, either by means of Asiatic pure lines or by means of the incorporation of genes for late flowering in short-day conditions in this lines is highly viable.Index terms: agronomic characters, genetic breeding, germplasm, Glycine max. COMPORTAMENTO DE GENÓTIPOS DE SOJA TIPO ALIMENTO E POSSIBILIDADES DE ADAPTAÇÃO ÀS LATITUDES BRASILEIRAS RESUMO -O presente trabalho foi desenvolvido na Universidade Estadual de Londrina (UEL), emLondrina, PR, com o objetivo de estudar o comportamento de genótipos de soja (Glycine max (L.) Merrill) tipo alimento, para posterior uso como cultivares ou em cruzamentos. Foram avaliados 104 genótipos, sendo 88 do tipo alimento, de sementes grandes, oito do tipo alimento, de sementes pequenas, e oito adaptados, tipo grão. O delineamento foi o de blocos completos ao acaso, com quatro repetições, considerando 12 caracteres de importância agronômica. Foi observada uma grande diversidade genética no germoplasma tipo alimento, havendo genótipos com alta produtividade e adaptados para época normal de semeadura. Programas de melhoramento genético da soja para consumo humano direto, no Brasil, são viáveis, seja pelo uso direto de linhagens asiáticas, seja por meio da incorporação de genes para florescimento tardio, em dias curtos, nestas linhagens.Termos para indexação: caracteres agronômicos, melhoramento genético, germoplasma, Glycine max.
