Abstract
The effect of inbreeding on yield potential per plant and the load of deleterious genes in maize (Zea mays L.) were studied. Twelve recycled hybrids obtained though inbreeding and selection on the basis line performance per se, along with their original hybrid PR 3183 and the check hybrid B73×Mo17, were tested in a R28 honeycomb trial under very low density (0.74 plants/m 2). Inbreeding depression was related with reduced yield potential per plant and increased CV of individual plant yield (estimated in F1 and F3), as well as with increased heterosis. The recycled hybrids were found to have improved yield potential per plant in both F1 and F3, lower CV values in F3, and lower inbreeding depression. Results were indicative of the effective exploitation of the additive genetic effects, which reduced the load of deleterious genes, and produced less heterozygous hybrids that were characterized by improved yield potential per plant.
