ABSTRACT

................................................................................................................................................................................................................................

Mutagenic effectiveness and efficiency of individual and combination treatments of EMS and gamma rays were assessed in Isabgol (Plantago ovata Forsk.) var. Mayuri. The experiment included total 16 mutagenic treatments (6 each for individual treatments of EMS and gamma rays and 4 combination treatments), selected on the basis of their LD50 values. Effectiveness and efficiency were calculated on the basis of biological damage of M1 generation and chlorophyll mutation frequency of M2 generation. While mutagenic effectiveness was found to be decrease with the increasing concentrations/doses of the mutagens, mutagenic efficiency showed variable trend depending upon the mutagen type and the criteria selected for its estimation. EMS treatments showed high mutagenic effectiveness than the gamma rays and combination treatments.

 

Key words: Isabgol, EMS, gamma rays, mutagenic effectiveness and efficiency, chlorophyll mutations, biological damage.
