This chapter discuss methods and factors to consider to prolong root shelf-life during marketing. The first observation is that different sweetpotato cultivars have varied susceptibility to water loss which dictates the differences in shelf-life. Among main forms of sweetpotato deterioration are water loss and rotting. Water loss is consistent between different seasons however, some cultivars perform better than others. Some of the major factors that control variations in susceptibility to water loss include reaction to root wound, probability of root to be damaged and root shape with round shape being less susceptible to breakage. This chapter concludes by singling water loss to sweetpotato deterioration. Further environmental effects on cultivar behavior require testing on multiple sites as it would inform on breeding programs.
