To determine the association among yield related traits on grain yield of mutant wheat, an experiment was conducted at the Agricultural Research Farm of R. B. S. College, Bichpuri, Agra (Uttar Pradesh). The application of physical mutagens such as X-rays, gamma rays, and neutrons, as well as chemical mutagens, for inducing variation is well set up. Induced mutations have been applied to the Joint offer of FAO/IAEA Division of Nuclear Methods in Agriculture, more than 1800 cultivars acquired either as direct mutants or derived from their crosses have been released globally in 50 countries. The correlation of twelve characters in wheat induced mutants was investigated. The number of spikelets per spike and spike length both had a significant and positive correlation with yield per plant. Selection for traits that are positively correlated with yield per plant could lead to increased yield. This suggests that selecting for these traits may be more effective in maximising grain yield.

Mycotoxins are toxic secondary metabolic products of various fungi, mainly belonging to the genera Fusarium (Trichothecenes, Zearalenone), Aspergillus (Aflatoxin) and Penicillium (Ochratoxin) and can be found in almost 25% of the world’s agricultural commodities. These compounds are toxic to humans, animals and plants and therefore, efforts should be made to avoid mycotoxin contamination in food and feed. It has been estimated that at least 300 of these fungal metabolites are potentially toxic to animals and humans. In India 50% losses of agricultural commodities are due to postharvest losses. A number of physical and chemical approaches have already been taken to reduce the effect of mycotoxins, but due to certain limitations of physical and chemical strategies prompted search for other solutions to the mycotoxin hazards. Thus, there is an increasing public pressure for a safer and eco-friendly alternative to control these organisms. Consequently, a new approach is applied for managing mycotoxins through transformations that offer specific, efficient and eco-friendly way for detoxification of mycotoxins. This review aims to brings about the up-to-date management strategies mainly through transformation (genetic and bio) to pre-vent or reduce post harvest damages to the crops caused by storage fungi and the contamination of food and feed by mycotoxins. It will make aware of the new technologies or management methods for mycotoxins through transformation. The transformation methods may become the technology of choice, as they offer a specific, irreversible, efficient and environment friendly way of detoxification that leaves neither toxic residues nor any undesirable by-products.
