“…The decline in plant height might be due to chromosomal damage resulting in premature activation of protein synthesis as documented previously [28,29]. Previous researchers have reported the decrement in growth attributes owing to modifications in enzyme activity, enzyme degradation [30], damage to cellular constituents and/or cellular DNA [31,32].…”

The determination of the optimum dose of radiation through its impacts on the growth attributes of the crop is the prerequisite for successful induced mutation breeding. For evaluating the impact of different doses of gamma radiation on wheat (Triticum aestivum), two wheat varieties DBW 187 and K 1006 were irradiated at six different doses (200, 250, 300, 350, 400 and 450 Gy) using a Cobalt-60 source at Bidhan Chandra Krishi Viswavidyalaya, West Bengal, India. Seed germination, survivability and seedling length of the irradiated seeds were measured at 7 days after sowing in laboratory experiments, while plant height, panicle length, grains per panicle and 1000 seed weight was recorded for field studies. It was observed that HIGHLIGHTS• Two varieties of wheat were irradiated with six doses of γ radiation• Seed germination, survivability and seedling length observed under laboratory conditions • Plant height, panicle length, grains per panicle and 1000 seed weight was recorded for field studies • LD50 for DBW 187 and K 1006 were found to be 272.71 and 278.61 respectively.

“…They are considered as the principle indicator of potential changes induced by the mutagens which can determine the clastogenic effects of the mutagens thereby permitting the exchange of chromosomes with successive genetic damages [150]. Moreover, the appropriate and effective dose treatments of the mutagens can be assessed through chromosomal aberrations to ensure the maximum outcomes from the breeding program [97]. Hence, in the present research work the genotoxic and cytotoxic effects of Monosodium Glutamate on Urginea indica Kunth were confirmed through the induction of significantly higher frequency of chromosomal aberrations.…”

Monosodium Glutamate is a food additive well-known as a flavor enhancer being used extensively in food industries. Also, it has long been used as a cheap source of fertilizer owing to the presence of high nitrogen contents in it. Furthermore, it also shows genotoxic effects on plants. Hence, in the present study the genotoxic properties of Monosodium Glutamate had been explored to assess its potential as a mutagen. The objective was specifically to find out its potential in inducing polyploidy in plants. For this, a medicinal plant, Urginea indica Kunth with immensely high therapeutic value was selected. The effectiveness and efficiency of Monosodium Glutamate on Urginea indica Kunth was assessed based on the records obtained after treatments in two generations, viz. M1 and M2 Generations. Its effectiveness and efficiency on Urginea indica Kunth pave a way for its use as a potential mutagen which can induce genetic variability among the selected wild species of the plants with great ease. Moreover, the higher degree of polyploidy obtained in the M2 generation established the objective of the experiment, that Monosodium Glutamate could be used with controlled, adequate dose and maintained experiment setup in inducing polyploidy in plants.
