Méthodologie de l'amélioration du blé tendre (Triticum aestivum L). II. Étude et analyse de deux premiers cycles de sélection récurrente

gime was performed with phenotypic indices which combine the main characters introduced in general wheat breeding. The analysis of the 2 first cycles was based on the comparison of the final population (PAwith the initial population (PA or with the 16-parent group introduced in PA It shows the efficiency of such a scheme with an increase in mean level for most characters studied. Moreover, the intrapopulation variability estimated by phenotypic variances (and genetic variances for PAremained at the same level except for the characters that were intensively selected. These evaluations provide a basis for discussion on a better way to insert and apply recurrent selection in a wheat breeding strategy.
