Effect of gamma rays and EMS on germination and survival percentage of annual chrysanthemum

Abstract

An experiment entitled “Mutation studies in annual chrysanthemum” was carried out during rabi season of the year 2021- 2023 at the farm of Horticulture Section, College of Agriculture, Nagpur. The experiment of M1 generation was laid out in randomized block design with three replications and eight treatments. However, the experiment of M2 generation was laid out in progeny rows with eight treatments consists of Control, 100 Gy, 200 Gy, 300 Gy, 400 Gy, 0.1% EMS, 0.2% EMS, 0.3% EMS. The different treated seeds of annual chrysanthemum with gamma rays and EMS had significantly influenced the vegetative characters and also created the variability. Significantly reduced the germination percentage of plants and survival percentage of plants in M1 and M2 generation of annual chrysanthemum.
