Studies on the biochemical properties of soybean (Glycine max) genotypes in response to charcoal rot incidence

Despite being one of the most economical source of protein and packed with several nutraceutical components, soybean does suffer from shortfalls that limit its utilization in food uses. Given the fluctuating production of soybean in the recent years due to several biotic and abiotic stresses, it has become important to breeding for quality traits in tandem with overcoming other biotic/ abiotic stress that affect crop productivity. Diseases on soybean is one of the major constrain in production in Maharashtra. Charcoal rot is a soil borne, rated as number one or two factors causing economic loss due to root and stem disease of soybean. In general, 30-50 % losses occur every year in soybean worldwide and recorded up to 77% in India considering the losses it has become important to study the biochemical properties of the crop for breeding for quality traits in tandem with overcoming other biotic/ abiotic stress that affect crop productivity. In the present study protein, proline, carbohydrate and oil content was evaluated. The highest protein content was recorded in the genotype AMS MB 5-19 (43.22 g/100g) and the lowest level was recorded in TAMS-38 (31.31 g/100g) genotype. Highest content of proline was found in AMS MB 5-19 (24.42 g/100g) and lowest amount of proline was found in AMS 475 (21.42 g/100g). Highest carbohydrate was found in AMS MB 5-19 (19.22 g/100g) and lowest amount of carbohydrate was found in AMS 475 (6.31g/100g). Highest oil content was found in AMS MB 5-19 (21.01%) and lowest amount of oil % was found in BRAGG (18.84%).
