RESUMEN

The RAPD analysis was conducted on genome DNA from 21 sets of rice, including 6 three-line hybrid rice combinations, separately derived from three different kinds of cytoplasmic male sterile (CMS) lines and their related parents. Out of 264 random primers screened first, 25 primers displayed well in polymorphisms. It was shown that only 7 bands amplified respectively from 7 primers were enough to discriminate the different types of CMS, the hybrid combinations and their parents.
