Abstract:
An experiment was conducted to study the impact of gamma radiation on vegetative and bud characteristics of Lilium hybrid cv. Zambesi in vM2 generation during the year 2020-2021. The experiment consisted of randomized block design with four treatments. The result revealed that in vM2 generation different gamma ray doses had major effect on the vegetative and bud parameters. Generally the treated population had reduction in all the parameters in vM2 generation compared to control. Maximum plant height, leaf length and leaf width were observed in T₁ (control) except number of leaves per plant recorded highest in T₂ while minimum was observed in T₄. Similarly days to bud appearance and bud break were delayed at higher doses of gamma ray (viz. 3.5 gy and 5.5 gy) compared to control. Number of bud per plant and bud length recorded highest in control except bud width where increase was seen in treatment T₂.
