Identification of Italian landraces of bean (Phaseolus vulgaris L.) using an image analysis system

The macro, called Bean.mcr, works quickly and accurately. The performance of the four classifiers was as follows: the first, for the identification of 15 landraces, 99% training set and 98.20% test set, respectively; the second, to identify two harvest years, 99% and 100%; the third, to identify three harvest years, 100% and 98.82%; the fourth, for the identification of the two different cultivation regions, 94.5% and 82.40%. The macro gives, to a certain extent, the possibility of tracing beans yield, in order to get a “market card” for landrace beans.
