COMPARISON OF RECURRENT SELECTION METHODS IN WHEAT: II. SELECTION RESPONSE IN NON INBRED POPULATIONS
The purpose of this study was to determine the mean genetic progress rate (AG) and genetic variance changes for grain yield (R) in 50 panmictic wheat (Triticum aestivum L.) populations, derived from the recurrent selection for R by eleven direct and indirect methods practiced in a F2 population. In order to achieve this objective, F1 seeds from original and selected populations were evaluated in spaced planting in two rainfed environments, in the 1993 summer season. The regression analyses showed that the lower AG values for R per year were obtained with methods that evaluated F1 progenies: half-sib family selection (2.13 %), full-sib family selection (3.33 %), recurrent selection for general combining ability (3.64 %) and mass selection (5.20 %), but only in mass selection, the AG was significant (p
