Abstract:

The experiment was carried out on gladiolus variety ‘Psittacinus Hybrid’ to know the best mutagen between physical mutagen (Gamma rays) and chemical mutagen (DES). The experiment was carried out at Floriculture Research Farm, ASPEE college of Horticulture and Forestry, Navsari during the year 2013-2014.The corms of gladiolus were treated with different doses of gamma rays viz. 5.5 kR, 6.0 kR, 6.5 kR, 7.0 kR, 7.5 kR and 8.0 kR and different concentrations of DES 0.1%, 0.2%, 0.3%, 0.4% and 0.5%. Different vegetative and flowering characters were taken under study. It was observed that there was negative correlation of sprouting and survival per cent with the different treatments and it was also noticed that survival per cent of DES treated corms was less compared to gamma rays. Looking at vegetative characters it was found that DES had more pronounced effect on vegetative characters similarly for flowering characters DES produced larger spikes and with more no. of florets as compared to Gamma rays. Plants were more responsive to treatment of DES as compared to gamma rays.
