Abstract
The spectrum and frequency of chlorophyll mutations was assessed in M2
generation in local cultivar of Horse gram (Macrotyloma uniflorum
(Lam) Co-1 with a range of EMS 10mM, 20mM, 30mM,40mM and 50mM and Gamma rays
10KR,20 KR,30 KR, 40 KR and 50 KR doses. All the mutagen induced wider spectrum
of chlorophyll mutations. In present investigation Chlorina, Xantha and Viridis
were found more frequently which indicated preferential induction of certain
type of mutations. Fairly dependent increase in chlorophyll mutant rate was
observed based on plant population and segregating progenies in M1
generation in M2 generation. All the three mutagenic effectiveness a
measure of the frequency of mutation induced per unit dose of mutagen and
mutagenic efficiency, proportion of mutation in relation to undesirable
effects, were higher with EMS treatments indicates more effective and efficient
mutagen than other two.
