Fig. 4
Three Si vs. Hi plots for the validation samples (from the eight fava bean varieties, n = 25) representing the closeness and classification of these samples to one of the three models’ classes of fava bean varieties. The samples that belong to a certain model class lie in the left lower quadrant with a small distance and leverage to the model for which they belong. The validation samples from the five traditional Egyptian cultivars lie in the lower left quadrant of the traditional fava bean class model, while Maryout and LUZ samples lie outside this quadrant with high leverage and/or distance to the tradition Egyptian fava bean model (a). Only Maryout validation samples lie in the lower left quadrant of Maryout class (new Egyptian varieties), while all other varieties lie outside this quadrant (b). Finally, only LUZ validation samples lie inside the lower left quadrant of the Spanish variety Luz de Otoño class whereas all Egyptian verities lie outside this quadrant (c).
