【Abstract】 RAPD analysis on Lilium regale and its 13 phenotype male sterility mutants initiated from irradiation bulbs was made by means of 300 random 10mer primers. Of the tested primers, 93 primers produced ideal amplification bands on all materials, 14 primers generated stable different polymorphic bands among mutant ’Wang 2G03’?mutant ’Wang 3G03’ and Lilium regale. 21 different polymorphic bands were found between ’Wang 2G03’ and Lilium regale. 25 different polymorphic bands existed between ’Wang 1G03’ and Lilium regale. It was showed that ’Wang 2G03’ and ’Wang 1G03’were two real different male sterility mutants of Lilium regale. From the 93 primers RAPD bands, the other 11 phenotype male sterility mutants showed no difference in comparison with Lilium regale. It was proposed that more test need to be made to identify whether they were real mutants.更多还原
