Abstract :

The experiment was carried out to induce variability in the sunflower ineds by physical mutagen, i.e., Gamma rays. Progressive decreases in germination and survival with increase in of Gamma ray doses were recorded in M1 generation. The different mutagenic treatments showed an inconsistent relationship with respect to mean and variability. However, considerable increase in variability in days to 50 % flowering, plant height, head diameter, days to maturity, seed yield per plant and oil content was observed.
