Resumo: Apomixis is a trait with a single genetic control (reviewed in OZIAS-AKINS, 2006). Therefore, can be manipulated through the conventional techniques of plant genetic improvement as well as genetic engineering techniques. Because of the prospect of controlling apomictic reproduction, interest on this trait has increased recently. The main interest in uncovering the apomixis pathway is the possibility of control and transfer of the trait to cultivated plants where apomixis does not occur naturally. Consequences of this strategy have been discussed by many authors (BASHAW, 1980; ASKER; JERLING, 1992; KOLTUNOW, 1993; CARNEIRO; DUSI, 2002; SPILLANE et al., 2004) as follows: fixation of hybrid heterosis vigor through seed propagation; the possibility of propagating and storing currently vegetatively-propagated plants by seeds; simplification of commercial hybrid seed production with consequent reduction in cost; simplification of breeding programs and consequently increasing the number of cultivars adapted to specific environments.
