Abstract: RAPD analysis for genetic diversity was conducted on 42 backbone parental lines in Indica hybrid rice breeding with 9 primers selected from 250 random prime rs. The results indicated that the genetic diversity in maintainer and restoring lines was small. The genetic similarity between them was up to
