Table 1: Mean squares of GCA and SCA in every traits
MS (GCA) MS (SCA)
Pod per plant 3,175 3,524
Pod length 1,817 0,852
Seed per pod 1,126 0,527
The GCA values are higher than one in every traits and larger than SCA values, expect
in the trait of pods per plant. The estimated GCA effects associated with each parent are
shown in Table 2.

The values of GCA very similar to each other, because of selected parents were very
similar respecting of yielding- features (excluding Foremos). The values of pod length
of GCA are correlated with the higher valueses of seed per pod of GCA in Margó,
Foremos, Presto, Mariza. The estimated of SCA effects are given in Table 3.
