      abstract = {Frequently, farmers in Puerto Rico complain that the  tuberous roots from the recommended varieties differ in  size, shape and weight, a situation that increases  difficulties for marketing. Baseline information on the  magnitude of losses related to inappropriate root size is  not available. The objective was to assess roots' fresh  weight distribution among varieties of sweetpotato of  common use in Puerto Rico. Four varieties were grown in a  location on the southern coastal valley. For this study  roots harvested at 162 days were selected. Roots were  weighed individually. Distribution of the individual root  fresh weight for each variety was compared to theoretical  distributions by using the Kolmogorov-Smimov Test. There  was a high frequency of light-weighted roots. The Normal  Distribution does not describe adequately the data for root  fresh weight distribution from any of the varieties.  Because of a high frequency of roots having lightweight,  Lognormal and Weibull Distributions appear more adequate  than the Normal Distribution to describe the actual root  weight distribution. Roots end to be too small for the  market, thus for commercial purposes, results stress that a  relatively high percentage of photosynthates accumulated in  the roots are lost. More emphasis on the selection for this  characteristic is needed.},
