Resume The genetic variability of four promising tropical-temperate maize populations developed in Benin was studied for three major maize diseases in tropical zone (rust, tropical blight and maize streak). Random sets of S1 families derived from the populations were evaluated in savanna zone using 10 x 10 triple lattices. Genetic variances of 75% tropical 25% temperate and 50% tropical 50% temperate populations were not significantly different for resistance to rust and resistance to tropical blight in the two crosses studied. For resistance to maize streak, the genetic variance of EV8443SR x (EV8443SR x FS14) (EFE) was significantly higher than that of EV8443SR x FS14 (EF). There was no significant difference between genetic variances of EV8443SR x (EV8443SR x DEA) (EDE) and EV8443SR x DEA (ED). The expected genetic progress was higher in the population ED than in the population EDE for resistance to the three diseases. It was lower in the population EF than in the poulation EFE for the three traits. EFE and EDE appeared better than EF and ED respectivvely, as a foundation population to improve resistance to rust, tropical blight and maize streak.
