Phenotypic correlation between seed size and other characteristics in topcrosses of vegetable soybean with grain type

This work was conducted to evaluate the phenotypic correlation between char acters in topcrosses between vegetable soybean with grain type cultivars (D oko and FT-2). Interesting values to facilitate selections were observed in correlations between one hundred seed weight (seed size) and days of matur ation and between seed size and pod width as visual score. Seed yield and s eed size were significantly correlated only in Doko's topcrosses. Estimated correlation from individual plants tended to confirm those obtained at mea n level plot. Depending on the soybean type (grain, sprout/natto and vegeta ble), the correlation values were different. Because of that it is recommen ded different selection strategies to evaluate distinct soybean classes. Co rrelation studies for each topcross are important, due to differences in pl ant performance as observed in obtained results.
