Post harvest behavior of different sweet potato (Ipomoea batatas (L.) Lam) germplasm under ambient conditions

Abstract

An experiment was undertaken to study the postharvest behavior of different sweet potato germplasm under ambient conditions. The study indicated that minimum physiological loss in weight was observed in BSP-23 and highest was observed in BSP-27. The higher and lower PLW of tubers was due to increased or decreased transpiration changes with progress of storage period along with the genetic makeup of the plant as well as prevailing environmental conditions. Maximum shelf life was recorded in BSP-23 whereas, BSP-7 recorded minimum. BSP-23 recorded maximum reducing sugars, non-reducing sugars and total sugars. Whereas, minimum was recorded in BSP-30 and BSP-27. Significant variation in quality parameters among different genotypes of sweet potato may be due to the inherent genetic makeup of the genotype and influence of environmental conditions.
