Author(s): UH Patil, AR Karale, SM Katwate and MS Patil
The present experiment was conducted on chrysanthemum cultivar ‘Local Golden’ which was irradiated with 0.5, 1.0, 1.5, 2.0, 2.5 and 3.0 Krad of gamma radiation. Reduction in survival percentage, plant height, number of branches, number of suckers per plant was observed after irradiation and with increase in dose of gamma rays. The LD50 is between 2.5 and 3.0 Krad. Plant height at time of bud initiation and flowering was maximum in control (45.29 cm and 79.90 cm, respectively), while minimum in 2.5 and 3.0 Krad treatments. Chimera in ray florets of flower was observed in one plant after 1.5 Krad treatment. The original shape of ray florets was flat with small tube at the base whereas in case of tubular mutant, shape at tip was spoon type and basal portion showed pipe or tube like appearance.
