Resumo
This work was conducted to evaluate the phenotypic correlation between characters in
topcrosses between vegetable soybean with grain type cultivars (Doko and FT-2). Interesting values to
facilitate selections were observed in correlations between one hundred seed weight (seed size) and
days of maturation and between seed size and pod width as visual score. Seed yield and seed size were
significantly correlated only in Doko’s topcrosses. Estimated correlation from individual plants tended
to confirm those obtained at mean level plot. Depending on the soybean type (grain, sprout/natto and
vegetable), the correlation values were different. Because of that it is recommended different selection
strategies to evaluate distinct soybean classes. Correlation studies for each topcross are important, due
to differences in plant performance as observed in obtained results.
