Abstract :To induce flower color mutants in Grasspea insert ignore into journalissuearticles values( Lathyrus sativus Linn.); variety “Pusa-24“, the fresh seeds were exposed to 4 different doses of gamma radiation as physical mutagens insert ignore into journalissuearticles values(100, 200, 300 and 400 Gy); and treated with 4 different concentration of Ethyl Methanesulphonate as chemical mutagen insert ignore into journalissuearticles values(5, 10, 15 and 20 mM ); and also combination of both mutagens. Due to mutagenesis broad range of flower color mutants in M 2 , M 3 and M 4 were obtained. Various unique and different flower color mutations like pink, purple, white and yellow detected against blue which is natural color in control progenies. Maximum flower color frequency was recorded in EMS treated seeds insert ignore into journalissuearticles values(20 mM); in 4th generation and lowest mutation frequency in 2nd generation was obtained in gamma rays insert ignore into journalissuearticles values(100 Gy); treated seeds. The results showed more flower color mutations happened in more dose /concentration of mutagens in every generationKeywords : Flower color, Mutation, Grasspea, Gamma radiation, EMS
