Crop improvement in Jasminum sambac through induced mutagenesis entails the insight on the sensitiveness of the individual plant materials of a species to different classes and nature of the mutagens. The current assessment was undertaken to analyse the mutagenic effect of acute gamma irradiation and EMS in Jasminum sambac cv. Ramanathapuram Gundumalli. Semi-hardwood cuttings of the plants were exposed to different dosage levels of gamma rays varying from 0 Gy (control) to 40 Gy and decapitated rooted cuttings were treated with EMS from 0 mM (control) to 90 mM. The M 1 V 1 generation was evaluated by treating the cuttings with four different doses of gamma rays (15 Gy, 20 Gy, 25 Gy and 30 Gy) and three concentrations of EMS (45 mM, 60 mM, 75 mM) formulated using respective LD 50 doses. The lethality dosage (LD 50 ) value for the cultivar Ramanathapuram Gundumalli was determined to be 21.37 Gy and 64.57 mM for gamma irradiation and EMS, respectively applying the probit curve analysis. The maximal reduction in the survival of cuttings of 75% and 71% correspondingly in gamma and EMS treatments was discerned at higher doses in comparison to the lower doses. The plants studied in M 1 V 1 generation for growth and flowering characters exhibited variable responses pertaining to differing doses or concentrations of the specific mutagenic means.

“…al., (2013), explained the substantial damage of meristematic cells and essential plant cell components at the physiological level of plants exposed to higher doses of gamma rays. The study carried out by Ghosh et. al., in 2018 reported that survival percentage of gamma treated cuttings ranging from 5Gy to 40Gy of different Jusminum species is varied with the species and recorded that LD50 value as 17.8Gy in J. grandiflorum, 28Gy in J. multiflorum and 25.1Gy in J. nitidum.…”

“…The mean shoot length per plant shows a decreasing pattern parallel to the plant height. The explanation from Ghosh et. al., in 2018 supported to prove these results the influencing of mutagenic agent as an inhibitor for vegetative growth performances such as shoot length, number of leaves and leaf length can be shown a decreasing pattern with the increasing of gamma irradiation dosage (5Gy to 40Gy) on Jasminum spp and Kannan, (1994) mentioned that J. sambac is a woody perennial plant which is inhibitory influence of ionizing radiation was well established.…”

Physical mutagenesis is an effective mutational breeding method for improving various growth and floral characteristics of ornamental plants. The experiment was undertaken with an objective to investigate the effect of various dosages of gamma irradiation on survivability, growth and floral characteristics of Jasminum officinale plants raised by rooted cuttings. The 60 CO Gamma irradiation source at Horticultural Crop Research and Developmental Institute, Gannoruwa was used to expose rooted plants to different dosages such as 0Gy, 17Gy, 21Gy, 25Gy, 29Gy and 33Gy. A Complete Randomized Design with four replicates having 10 plants for each replicate was practiced. The results revealed that gamma irradiation dosage from 25Gy to 33Gy significantly decreased the survivability of J. officinale plants (P<0.05). LD50 of gamma radiation on J. officinale was occurred around 33Gy at maturity stage. Plant height and shoot length were significantly reduced by gamma irradiation dosages of 17Gy to 33Gy compared to the control and significant reduction of shoot number was observed at 33Gy. Gamma irradiation with 17Gy dosage, it showed a significant reduction in petal width (0.82 cm) of flowers. None of the other dosages were able to develop a change in the floral characteristics of J. officinale. The study showed that 33Gy gamma irradiated plant, it is having significant reduction of plant height, number of shoots and shoot length hence it could be domesticated as a dwarf and potted plant.

“…Improvement of a vegetatively propagated crop like J. auriculatum depends on the presence of genetic variation in the existing germplasm. It has been more than three decades since an improved variety in J. auriculatum was developed, viz., CO.2 Mullai, which Tamil Nadu Agricultural University developed, Coimbatore, Tamil Nadu in the year 1988 (Ghosh et al, 2018). Considering the breeding behaviour of jasmine, mutation breeding is an effective tool to create variation in terms of corolla tube length, fragrance, and pest and disease resistance, as well as for improving the yield.…”

Vegetatively propagated crops like Jasminum auriculatum have a constraint in genetic variation due to a narrow genetic base that restricts the insights in any crop breeding programme. Mutation breeding is a potential tool that directs a way to create desirable variation effectively in vegetatively propagated crops. The optimum dose of mutagen is the one which produces the maximum frequency of mutation in turn the variation, with minimum killing. The aim of the present paper unveils the Lethal Dose (LD50) and the growth reduction dose (GR50) for both Gamma irradiation (GI) and Ethyl methane sulphonate (EMS) for the ecotype ‘Muthu Mullai’ of Jasminum auriculatum. These parameters of GR and EMS treated cuttings were analysed by considering the GR50 values of the mortality rate (57%, 48%), survival percentage (12.479Gy, 13.268mM), shoot length (18.59Gy, 18.28mM), root length (20.39Gy, 18.17mM), number of leaves (22.29Gy, 17.47mM), number of sprouts (22.97Gy, 16.17mM), vigour index (10.43Gy, 11.05mM), leaf length (21.61Gy, 19.90mM) and leaf width (19.2Gy, 16.17mM). The LD50 value was 12.479 Gy for GI and 13.268 mM for EMS treatment. The GR50 for different growth parameters ranged from 14.93 to 22.9 Gy for GI and 1.05 to 19.9 mM for EMS treatment. The mutagenic efficiency and effectiveness were 214.96 and 89.36 for GI and 48.66 and 33.77 for EMS treatment, respectively. These doses can be used for generating considerable variation, which can be put to use in future crop improvement programmes for Jasmine.
