Inbreeding depression and heterosis of hybrids in F 2 populations of maize in the Sao Paulo State, Brazil. Heterosis and inbreeding depression are complementary phenomena, both important to the establishment of breeding strategies, such as conventional hybrids and population breeding. This study aimed to evaluate the agronomic traits of hybrids in F 2 populations, estimate of heterosis in relation to the average of the parents and determine the inbreeding depression in F 2 parents populations.

Ten hybrids of F 2 populations, five F 2 parents populations and the respective commercial hybrids HC were evaluated for male flowering, plant height, ear height and grain mass. Plants were evaluated in Mococa and Palmital counties at the Sao Paulo State and the experiment was arranged in a completely randomized block design. The estimated inbreeding depression from F 1 to next F 2 generation ranged from The heterosis in relation to the parents’ mean was Based on these results, it was possible to highlight two hybrids of F 2 populations with high yield potential, high average heterosis and F 2 populations with potential for extraction of inbred lines.
