Experimental study on biochemical parameters and yield of M4 Indian mustard mutants

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.
