- •
Variations in physicochemical properties of starches were found in sweetpotato varieties.
- •
TNG31 and TNN18 produced starches with distinctly different physicochemical properties.
- •
AM content was related to pasting and thermal parameters, swelling, solubility, and textures.
- •
GBSS and SS activity reflected the abundance of GBSS and SS mRNA in TNG31 and TNN18.
- •
Expression of AGPase, GBSS, SS, and SBE in TNN18 substantially increased AM content.
