The influence of mutations on the nutritional value of Rapeseed Meal (RSM)

Anubhuti Sharma

Background: Members of family cruciferae contain many health promoting and potentially protective phytochemicals including folic acid, phenolics, sinapines, carotenoids, selenium, glucosinolates and ascorbic acids. However, presence of antinutrients e.g. glucosinolates remains a limiting factor for the use of Rape Seed Meal (RSM) as animal feed. Mutation breeding method is rapid, potential and valuable tool to create genetic variability for various quantitative and qualitative characters in crop plants. Induced mutations are produced by the use of mutagenic agents like physical mutagens (x-rays, Gamma rays etc.) and chemical mutagens (alkylating agents, base analogues etc.). However gamma rays act on genetic material by ionization leading to more of chromosomal rather than point mutations and gamma rays are successfully used in plant breeding program because of its simple application, good penetration, reproducibility and high mutation frequency and less disposal problems. Objectives: Two Indian mustard varieties were studied for biochemical analysis to explore the potential mutations (Physical and Chemical) for raising confidence in using oilseed meal in monogastric diets. This study will focus on the variability of RSM biochemical composition and the influences of mutation on this and major phytochemicals.
