Abstract: Mutagenic progenies M2, selected from peanut variety Luhua11 irritated by γ ray of 60Co,had significated difference on leaf characters and plant types.The DNA polymophisms of seven mutants were analysed by using 107 pairs of peanut SSR primers.The polymorphism was various among mutant materials and origional variety Luhua11.Mutant materials had more than two different loci from origional variety.Polymorphic analysis of SSR marker indicated that mutation can be induced by γ ray of 60Co,mainly showing chromosome deficiency and chromosome duplication.The genetic similarity( GS) among 101 mutagenic progenies M2 were calculated based on the data from SSR markers.The value of GS ranged from 0.457 to 1.000,with an average of 0.862.The variance ranges of genetic similarity of mutagenic progeny M2 and their original variety Luhua11 were 0.692-1.000.The analysis of molecular markers indicated that abundant genetic variations can result and genetic bases in original varieties can be broadened from the γ-ray radiation.

Key words: Peanut( Arachis hypogaea L. ), SSR Marker, Irradiation inducement
