Induced mutation in tomatillo (Physalis ixocarpa Brot.)

To induce mutation in tomatillo (Physalis ixocarpa Brot.) commonly grown for its fruit value, seeds were treated with three alkylating agents (dimethyl sulphate, diethyl sulphate and methyl ethane sulphonate) and gamma rays. Seven viable and five chlorophyll mutant types were screened both from M₁ and M₂ generations. The isolated mutant lines are described and evaluated with reference to their beneficial value.
