Abstract: To study the proximate biochemical composition and yield of twenty M₄ Indian mustard mutants, an experiment was conducted and work was subjected to the comparative evaluation of its chemical and biochemical parameters viz., total chlorophyll, nitrogen, phosphorus, potassium, protein, and oil. Among these twenty mutants, the highest chlorophyll, N, P, K at 25, 45, and 65 DAS, and protein and oil after harvesting was obtained from ACM₁₈, ACM₁₂, ACM₆, ACM₈ and ACM₄. In case of proximate analysis, the highest chlorophyll, N, P, K, protein and oil were recorded from ACM₁₈. The oil content of different mutants of mustard varied from (33.30 - 42.67%). ACM₁₈ (28.13 %) contained the highest amount of seed protein. All the chemical and biochemical traits were showed highly significant and positive correlation with seed yield. Substantial genetic variability exists for chemical composition and nutritional traits which could be utilized to suggest the future strategy. Hence, these five mutants are recommended for breeding programme and testing.
