“…Moreover, the treated populations were hexapetalous petals instead of five (in control plant) which is the index of increased number of seeds and better yield. The similar character was also noticed in Nigella sativa induced by gamma rays 13 . Apart from yield, big seeds size also comprised higher quantity of important chemical constituents which are gift for pharmacological domain and enhanced level of nutritive oil.…”

In the present situation of variable climatic conditions, global warming and sky-high populations, sustainable boost in the agricultural productivity is the utmost priority. View this point, induced mutation is the best approach to create the new genetic variability. The present study has been conducted to study the effects of gamma rays on Nigella sativa L. var. NRCSSAN-1. The seeds of Nigella sativa were mutagenized with 25, 50, 75 and 100 Gy radiation of gamma rays to develop a viable mutant. Different qualitative and quantitative traits of mutant plant were screened time to time and compared with control (untreated/normal plant). A macro mutations were induced affecting all plant parts and different morphological variants were screened and isolated on the basis of economic importance. The different morphological parameters such as plant height, number of fertile branches per plant and number of capsules per plant, number of locules per capsule, number of seeds per capsule and 1000 seeds weight were increasing with decreasing the doses. The different morphological traits having positive and strong correlation, will definitely be helpful in selection of improved mutants in subsequent generations. Cytological abnormalities were increasing with increasing the doses. The most abnormalities were seen in 100 Gy and lowest in 25 Gy. It is concluded that gamma rays at its optimal doses (25 Gy and 50 Gy) are ameliorative for medicinal herb-Nigella sativa. L.

“…Gamma irradiation was more potent in inducing higher frequency of mutation than EMS in celery and ajowan (Paul and Datta, 2005). Nigella seeds expose to gamma rays increased the seed weight and seed number as compared to the control plants (Kumar and Gupta, 2007).…”

“…Although meiotic chromosomal aberrations have been studied in different plants, comparatively less attention has been given to them in faba bean. Cytological abnormalities, induced by single and combined mutagen treatments, have been reported in some cereals (Suganthi and Reddy, 1992), Triticale (Edwin and Reddy, 1993b), Hordeum vulgare (Kumar and Singh, 2003;, Capsicum annuum (Dhamayanthi and Reddy, 2000), Solanum melongena (Zeerak, 1991), Nigella sativa (Kumar and Gupta, 2007), Cicer arietinum (Kamble and Patil, 2014), Vicia faba (Fatima and Khan, 2009;Laskar and Khan, 2014; and Vigna spp. (Goyal and Khan, 2009).…”

Current world scenario of hunger and malnutrition problem is posing a great threat to the human civilization. Millions of people are undernourished globally according to the reports of Food and Agriculture Organization (FAO, 2015). Pulses and cereals have been used for their high percentage of proteins and carbohydrates in seeds. Pulse crops also have the ability to enrich the soil fertility due to their nitrogen fixing ability of their root nodules. Further, it is not only the high protein content of pulses for which they are important, but the amino acid profile of these proteins is such that the mixed diet of cereals and pulses has superior biological value than either of the components alone. However, with increase in population, per capita availability of pulses is getting reduced. As against recommended daily requirement of 50-60 grams, current per capita availability of pulses in India is less than 30 grams per day. India is the largest producer and consumer of pulses and depends mostly on pulses and cereals for their food. Urbanization and drastic climatic changes like drought, global warming, different environmental stresses etc. have led to considerable loss of crop productivity throughout the world leading to food insecurity. Scientists all over the world are using sophisticated approaches in developing improved varieties of crop plants that are high yielding and show considerable resistance to drastic environmental changes. Physical and chemical mutagenesis has been proved to be a convenient tool compared to other conventional processes in inducing desirable variability in crop plants related to yield and other components. In the light of above all, it is necessary for a scientist to study in detail the all aspects of different approaches that are used to increase the yield and productivity in different crop plants. The current review covers all aspects of study during the different approaches of physical and chemical mutagenesis for increasing food security and developing high yielding and stress resistant plants.
