Abstract

Present investigation entiteled ‘Influence of Different Germplasm on Physiological and Biochemical Characters in Sweet Potato (Ipomoea batatas)’ was carried out in the Department of Horticulture, Rajasthan College of Agriculture, Udaipur to evaluate the physiological and biochemical variation in sweet potato (Ipomoea batatas L.) germplasm”. In this research, sixteen diversified sweet potato germplasm were evaluated under randomized block design with three replications. The result reveled that maximum protein (7.24%) in ‘CO-3-4’, starch (22.80%) in ‘Sree Nandini’ However, Overall with respect to physiological character i.e leaf area index (3.30), photosynthesis rate (1.01 µmol m-2s-1) and respiration rate (4.70 µmol m-2s-1) at 90 DAP and tuber yield (40.73 t ha-1) attributing characters ‘CO-3-4’ found to be superior over other genotypes.
