Résumé
In this work, we study two different groups of yield components (flowers per node, ovules per ovary, grains per pod, grains per ovule, pods per flower, pods per node, pods per plant, seed weight and yield per plant) in several generations (parental, F1 and F2, F3, B1, B1s, B2 y B2s segregations) for Vicia faba, by using principal components analysis. The objective is to assess the behaviour of these traits in each generation, and thus to determine the most effective method of using the improvement efforts in this species. We have employed advanced selection lines as parentals, and these pure lines have been crossed several times. The original traits were grouped similarly with respect to the first two principal components, explaining more than 75 per cent of total variation in the parental, F1, F2 and F3 generations, but not in the backcross generations. Genre blocks in the parental generation seem to be maintained in the F1, F2 and F3, and broken in the backcross generations ; backcrossing and not selfing allowed for recombination of quantitative traits
