Gamma rays effect on frequency and spectrum of chlorophyll mutation in chickpea (Cicer arietinum L.)

Abstract

The present investigation was undertaken to study the frequency and spectrum of chlorophyll mutations of different doses of gamma rays in variety Uday. No chlorophyll mutations were observed in the control population. Highest mutation frequency of chlorophyll mutation (1.22%) was induced at 10kR presoaked dose of gamma rays treatment. The spectrum of chlorophyll mutations (albino, xantha, chlorine, viridis and striata) were observed and grouped. Except striata, remaining four kinds of mutations viz. xantha, chlorine, viridis and albino were more frequently. The overall mutation spectrum showed that xantha (0.701%) occurred with the highest frequency followed by chlorine (0.621%), albino (0.408%) and viridis (0.307%).
