Grape shapes

ulations were made about the shape of each grape. Every grape was also manually rated based on elongation.

"Visual inspection supported the SigmaScan analysis," reported the researchers.

The grapes used for the study were frozen at the time of harvest and did not need to be thawed or cut to be photographed. Ten grapes were photographed at one time, but more grapes could be shot and studied in a single photo in the future to further the speed of study. In this way, SigmaScan improves efficiency, and because the fruit is still intact, it can also be used for additional studies or consumption.

This method has potential for future breeders by helping them to select grapes based on degree of elongation, and can also be applied to studies of other fruits. Although none of the elongated grapes have been released for public use as yet, it is hoped that in the future these new and unique grapes will be an addition to the expanding fresh fruit profile for American consumers.
