Rice (Oryza sativa L.) is one of the most important staple crops in the world. However, the increase in rice production is not keeping up with the demand increase this cereal. The occurrence of low temperatures is one of the main limiting factors to rice yield increase in temperate and tropical regions with high altitude. This study aimed to verify the differential tolerance to low temperatures in eight rice mutant genotypes in relation to their cvs. of origin during periods of germination and growing, and analyze the genetic variability between them through microsatellite markers. For the germination period, the tolerance indicators germination percentage (PG), mean germination time (GMT) and germination speed index (GSI) were used, while ...
