However, there are significant differences among methods and it is important to compare them in order to emphasize the best one. The objective of this study was to determine the selection progress in the Tuxpeno and ETO populations and to determine the heterosis effect in the crosses among different Tuxpeno and ETO population cycles.Collection: CIMMYT Staff Publications Collection
