The present study was conducted during 2013- 2014 to find out the effect of induced mutation on in vivo growth parameters in ‘Camarosa’ strawberry by following CRD factorial design. For the induction of variation explants (Runner tips, shoot tips and leaf disc) were subjected to different concentrations (0.1%, 0.2%, 0.3% and 0.4%) of EMS along with control for various treatment durations (1.5 hr, 2.5 hr and 3.5 hr). The concentration 0.4% was found lethal to the plants. The runner tip explants treated with EMS concentration 0.1% for duration 1.5 hr. gave maximum plant height (16.8 cm), plant spread (30.8 cm²), crown height (25.3 mm), crown diameter (16.3 mm), number of leaves per plant (15.5), leaf size (31.1 mm × 30.3 mm) and was found best among all the treatment combinations. While among various explants used, the runner tips explants was found best followed by shoot tips, leaf disc (abaxial) and leaf disc (adaxial). As the increased EMS concentrations along with treatment duration there was a gradual decrease in the in vivo growth parameters of strawberry. In future, these experimental results will prove very useful for induction of variability in this fruit crop.
