The present investigation was carried out at the Floriculture and Ornamental section, Department of Horticulture, University of Agricultural Sciences, Gandhi Krishi Vignana Kendra, Bengaluru during 2020-22. The experiment was laid out in factorial randomized complete block design replicated thrice with eighteen treatment combinations of varieties and gamma irradiation doses. Six gamma doses i.e., 15 Gy, 25 Gy, 35 Gy, 45 Gy, 55 Gy and control (untreated) as treatments were imposed on three varieties of gladiolus Arka Gold, Arka Pratham and Arka Amar. Number of days taken for sprouting was delayed with increased gamma dosage. The results of two generations (2020-21 and 2021-22) data showed that 25 Gy gamma rays enhanced the most of the quality parameters. Arka Amar showed maximum variations it is on par with Arka Gold. Gamma doses of 55 Gy is not good for quality parameters.
Gladiolus, Arka Gold, Arka Pratham, Arka Amar, gamma rays
In the present investigation gamma irradiation had exerted the significant effect on quality parameters in all three cultivars of gladiolus Gamma irradiation doses at 25 Gy and 15 Gy found beneficial for various traits in gladiolus. Medium to higher doses of gamma rays i.e., 15 Gy, 25 Gy and 35 Gy can applied in gladiolus corms for improvement. In general, the expressions of characters were decreased and retarded with 55 Gy.
