“…The decrease in plant height after exposure of the rooted cuttings to the colchicine and EMS has been due to disturbances of auxin synthesis and chromosomal aberrations. It was agreed with the results of Gupta and Gill (1985) [5] in Chrysanthemum coronarium when treated with colchicine and Vaidya et al (2016) [9] and Kapadiya et al (2014) [8] also have similar opinion when treated with EMS in chrysanthemum. There was significant decreased in number of branches plant -1 over control T10 (19.63) in chemical mutagen maximum branches plant -1 (17.61) was recorded at 0.01% EMS (T4) which was at par with T1 (17.11), T5 (16.16) and minimum (11.46) branches plant -1 were observed in 0.03% colchicine T3.…”

A field experiment was carried out at Department of Horticulture, Vasantrao Naik Marathwada Krishi Vidyapeeth Parbhani. (Maharashtra) during kharif season of the year 2017-2018. The experiment was laid out in Factorial Randomised Block Design with thirty treatment combinations. The treatments comprised of two factors i.e. factor A and factor B. Factor A consist of 3 varieties (V1-Raja Pandharpuri,V2-Brown and V3-Shinaton) and factor B consist of 10 levels of chemical mutagen (colchicine T1 -0.01%, T2 -0.02%, T3 -0.03%, T4 -Ethylmethanesulphonate (EMS) 0.01%, T5 -0.05%, T6 -0.1%, T7 -0.5%, T8 -1.0%, T9 -1.5%,T10 -Control) in Chrysanthemum. The different treatments to rooted cuttings of chrysanthemum varieties with colchcine and EMS had significantly influenced the vegetative and flowering characters and also create the variability. Significant reduction occurs in both colchicine and EMS treated seedlings of chrysanthemum varieties in terms of plant height, branches plant -1 , plant spread, Diameter of main stem and Number of leaves plant -1 Whereas leaf area and Petiole length was increased due to the colchicines and decreased due to EMS treated population of chrysanthemum varieties over control. The higher dose of colchicine and EMS delayed the flower bud initiation, flower opening and 50% flowering.

“…It may possibly be due to the inactivation and/or disturbances in the auxin synthesis (Gordon, 1957) and extent of chromosomal aberrations (Sparrow and Evan, 1961). Similar evidences have been documented in Bougainvillea by Datta and Banerji (1997), Gupta and Shukla (1974) and in chrysanthemum by Misra et al (2009) and Kapadiya et al (2014).…”

Mutation breeding is an established method used for crop improvement and has played a major role in the development of many new flower colour shape mutant cultivars in ornamentals. The present study was undertaken to induce mutations in Bougainvillea spectabilis Willd. cv. Lalbagh using a physical mutagen (rays) and a chemical mutagen (Ethyl Methane Sulphonate) for creating novelty during 2014-15 at TNAU, Coimbatore, Tamilnadu, India. Hardwood cuttings were treated with three doses of-rays (5.0, 7.5, 10.0 Gy) and three concentrations of Ethyl Methane Sulphonate (0.8, 0.9 and 1.0%). The first mutant-vegetative (M 1 V 1) generation was evaluated for various morphological traits. Sprouting percentage and survival rate of seedlings gradually reduced with proportional increase in dose concentration of mutagens. All the morphological traits recorded a declining trend with increasing mutagenic treatments. Some of the morphological mutants' viz., dwarfness, early flowering and thornless stem were noticed within the mutagen treated plant population. Nine different types of chlorophyll mutants were observed namely albina, albina green, xantha, chlorina, viridis, yellow viridis, striata, maculata and variegated type. Among the chlorophyll mutants recorded, chlorina was more predominant followed by maculata and viridis. With regard to mutagenic treatments, EMS 1.0% recorded more number of morphological mutants (12 Nos.) and chlorophyll mutants (20 Nos.). The 5.0 Gy dosage of-radiation recorded the highest mutagenic effectiveness (215.20) and efficiency (122.69) than other treatments. The highest mutation rates in terms of effectiveness (161.81) and efficiency (75.62) were recorded in EMS than-radiation in Bougainvillea cv. Lalbagh. 1.1.-irradiation Three radiation doses viz., 5.0, 7.5 and 10.0 Gy were used to treat the hardwood cuttings along with the untreated cuttings as control.-irradiation was given using 60 Co-source

“…Abnormalities in the colour, form, and texture of leaves following irradiation have been reported in rose, carnation, chrysanthemum and other ornamental crops by several workers (Singh et al, 1999;Kumar 2002, Kumari et al, 2013. Kapadiya et al, (2014) also reported that vegetative abnormalities were higher at gamma rays.…”
