Effect of induced mutagenesis in M1 and M2 generations of cumin (Cuminum cyminum L.)

Cumin is an important spice that has been used for centuries in various cuisines around the world. Two cumin varieties (GC 3 and GC 4) were subjected to mutation understand macromutational modifications. Ethyl methane sulphonate (EMS) @ 0.6% gamma rays (190 Gy) significantly reduced germination plant survival percentage as compared 0.2% EMS 130 Gy. Physical mutagens showed higher suravival than chemical mutagens. However, mutagen treated plants more sterility physical Chlorophyll mutations confined rare albinos small number of xanthas M2 generation.
