Rice (Oryza sativa L.) is unequivocally one of themost important food crops that feed the largest proportion of theworld’s population (Maclean et al., 2002). The demand for riceproduction will continue to increase in the coming decades,especiallyinthemajorrice-consumingcountriesofAsia,AfricaandLatin America, due to the population growth and cropland losses(Maclean et al., 2002).
