Abstract: This paper studies dried broad bean seeds' induced effect after ⁶⁰Co-γ ray treatment.The results indicate that different doses of radiation hare remarkable influence on M₁ breeding period,biological traits and photosynthesis physiology.With the increase use of doses the breeding process is reduced and breeding period is prolonged;plant height,number of tillers,pods per plant,grains per plant and weight per hundred grains all decrease gradually.In addition,coefficient of variation increases;after the inducing treatment,chlorphyll content of blades is identical to that of photosynthesis change rate,i.e.,the treatments before podding are higher than the controlled,and lower than the controlled after podding.

Key words: broad bean, ⁶⁰Co-γ rays, induced effect
