The genealogical tree of F4 and F5 inbred lines derived from the selfing and selection of two F1 adapted to two different growing cycles correlates in different degrees with the dendrogram derived from the similarity matrix that was built using the bands obtained by RAPD analysis of the mentioned inbreds. Three clusters can be distinguished in the dendrogram. The inbred lines derived from the hybrid adapted to early planting cluster together and the same occur with all except two of the inbred lines derived from the hybrid adapted to late plantings, indicating that the different agronomical behavior of the two groups of the inbred lines derived from the hybrid adapted to late plantings, indicating that the different agronomical behavior of the two groups of lines has a refection in the bands they generate. Correlation between the genealogical tree and the dendrogram is weaker in the lines derived from the second hybrid, suggesting the inside the F2 population derived from this hybrid fixation had not been so fast, a higher degree of recombination had occurred and it was possible through strong agronomic selection recover similar genotypes following different selection paths in the genelogical tree.
