Abstract: Autotetraploid rice is a special germplasm with four sets of genome that is derived from diploid rice treated by colchicine. Compared with its diploid progenitor, the chromosomes and genome of the autotetraploids are doubled, thus the phenotype or morphology of the autotetraploids, especially the re
