Abstract
Increased malnutrition and food insecurity for the past several years in countries, like India, is point of great concern. Present study was undertaken to reveal the potential role of mutagenesis to induce genetic variability of total seed Fe (μg g-1) and Mn (μg g-1) contents and their correlations to the yield/plant (g) in chickpea. Fe and Mn deficiencies are usually responsible for major malnutrition conditions, while lower yield of crops results to food insecurity. Seeds of chickpea were treated with ethylmethane sulphonate (EMS), gamma rays and their combinations and studied their effects on the components of variation for yield/plant, the total seed Fe and Mn contents. Six high yielding mutants were isolated in M2 generation and their Fe and Mn contents were evaluated. Positive correlation was seen between total Fe and Mn contents to yield in the isolated mutants at lower doses of mutagen while the correlation between Fe to Mn contents was found to be negative.
