In a breeding program for improving drought resistance in Vicia faba the water status of four highly homozygous genotypes of faba bean was studied in field in southern Italy, throughout the growing period of the crop. One of the genotypes was of major type (Aguadulce) and the other three (Manfredini, Vesuvio and Maris Bead) were of minor type. Leaf water potential and diurnal pattern of stomatal resistance were studied together with stomatal and trichome anatomic and physiological features. No significant differences in any of the characters were observed among the varieties and therefore no inferences on the relationships between water status of plant and drought tolerance could be drawn
