【Abstract】 Rice variety Yuexiangzhan and its mutants induced by high pressure, were studied by using microsatellite marker and soluble protein content analysi s. Results indicated that 11 of the 88 microsatellite primer pairs showed polymorphism. The polymorphic frequency was 3.4%-11.3% between mutants and Yuexiangzhan. The polymorphic markers were randomly located on rice chromosomes. The more similar the plant type of the mutants looked like their original variety(Yuexiangzhan), the less polymorphic loci were obtained. In addition, content of soluble protein in leaves of mutant was significantly lower than that in the original variety.更多还原
