Souza CLJ (2011) Cultivar development of allogamous
Changes in weather patterns at coffee origins mean a general global increase in instances of these plagues, and Robustas allogamous
genetics allow it to adapt to changing climates without intensive human intervention.
Experimentally produced allogamous
seeds would enhance diversity in restoration programs.
plant breeding programs, it is essential to generate base populations that can be used in the future as a source of inbred lines for obtaining superior hybrids (HALLAUER et al., 2010).
Self-fertilizations are important to obtain lineages for the production of commercial hybrids in allogamous
plants and for genetic studies.
Corn (Zea mays L.) is a diploid, allogamous
species that belongs to the Poacea family, originated in Mexico and Central America.
Reproductive studies have revealed that a large number of plant species are allogamous
or possess a mixed mating system that is predominantly allogamous
(Gusson et al.
The use of molecular markers is a powerful tool in the genetic study of populations, RAPD (Random Amplifies Polymorphic DNA) being suitable for the analysis of genetic diversity in natural populations of allogamous
species (Ferreira and Grattapaglia, 1998).
speltoides is considered by Hammer (1980) as typically allogamous
(cross fertilized) and Ae.
vulpiseta are preferably allogamous
species, while in S.
It is a monoecious, wind-pollinated, and allogamous
species (Schaffalistzky de Muckadell 1955; Metzeau et al.
On the diploid level a distinction will be made between autogamous and allogamous
crops, the latter in several examples known as crop-weed complexes.
