ABSTRACT

In the present investigation, viable macromutants with changes in stature, duration, leaf,
pod and sterility were recorded in M2 generation of cluster bean. A total of 54 and 39 macromutants were isolated from EMS and SA treatments, respectively. In the EMS treatments, the mutation spectrum was much wider (nine types of mutants identified) at 0.8% and narrow
(four types of mutants identified) at 1.0% and in SA treatments the mutation spectrum was
wider at 0.03% (ten types of mutants identified) and narrow at 0.01% (two types of mutants
identified). In general, the mutation frequency was high on M1 plant basis than M2 plant basis
for both the mutagens viz. EMS and SA. The frequency of viable mutation on M1 and M2 plant
basis exhibited an inconsistent trend with increase in EMS and SA treatments.
