Seeds of CO-1 variety were treated with .gamma.-rays and EMS (ethylmethane sulfonate), each in 5 doses, 10-50 kR and 0.5-2.5%, respectively. The chlorophyll mutation rate was characterized by linearity at low to medium doses and saturation as well as erratic behavior at high doses. As per mutation rate, estimated on the basis of M2 plants, EMS induced a high frequency. The spectrum consisted of albina, chlorina zantha, albo-viridis, tigrina (3 types) and striata (2 types), with tigrina being predominant. The treatments varied in their spectrum, with 2.0% yielding the widest spectrum of mutants.
