Conteúdo: | Molecular markers have been used to predict the genetic variance of segregating soyabean populations by measuring the genetic distance between parents. The genetic distance among 6 pairwise combinations of 4 soyabean lines grown in Southern Brazil were analysed. The AFLP-based distances (AFD) were estimated with 21 primer pair combinations. Additive genetic variance (D) was estimated in 100 advanced inbred lines for each cross for 7 traits, including grain yield, for 4 sowing dates and 4 years. Results showed a low but significant overall correlation between grain yield variance and AFD in the average of the 4 years and sowing dates. Considering the sowing dates the highest correlation was in October. Significant correlations were also found for five out of the remaining traits evaluated. We found no significant correlations between D and parentage coefficient for all traits evaluated, except for 100 seed weight..
