Abstract: Autotetraploid rice original variety (2n=4x=48) were created by doubling thechromosome number of diploid rice variety (2n=2x=24).Pooling together thedata from comparing the 4x original varieties with their corresponding 2x varietiessince 1979,it was found,that tetraploidy could cause variation of ma
