Abstract
Starch pasting properties of seven sweetpotato varieties at two levels of potassium fertilizer were analyzed by a rapid visco-analyzer(RVA).RVA pasting curves of sweetpotato flour generally have type B and type C.The difference in the breakdown of the starch among the genotypes was greatest.The breakdown was negatively correlated to peak viscosity(r=-0.71~(**)).Starch content was positively correlated to peak viscosity(r=0.59~*) and the breakdown(r=(0.74)~(**)).The amylose content was also positively correlated to the breakdown(r=0.89~(**)).Potassium fertilization had little effect on the starch pasting properties.The results showed that a key factor altering starch characteristics of sweetpotato was genotype variation,but not potassium fertilization.
