Abstract
Polyploidy has played a significant role in the evolution of higher plants (Leitch and Bennett 1997), having helped in tremendously increasing the number of species and sometimes of genera on the planet Earth. It is the most rapid method known of producing radically different but vigorous and well-adapted genotypes (Stebbins 1950); for this reason, it is of great value in plant breeding, more importantly the allopolyploidy. The significance of polyploidy in the plant world can be visualized by considering its high incidence among angiosperms, including the leading commercial crops, such as wheat, sugarcane, oats, cotton, tobacco, apples, pears, plums, Rubus, etc. (Table 5.1). This incidence confers some important advantages, viz. heterosis, gene redundancy and asexual reproduction (Comia 2005).
