Abstract
In summer 2003 a first search was done whit the goal of finding adult walnut seedlings with leafs free of Xanthomonas arboricola pv. juglandis (Xaj) spots. During that year about 150 walnut trees were pre-selected. However in successive years they had been discarded a number of genotypes that had shown some Xaj spots on leaves. At present they remain selected only 25 genotypes that year-after-year were keeping their leaves and nuts free of Xaj spots. In February 2007 some thin shoot tips out of the 25 genotypes had been removed and set to IMIDA of Murcia to be evaluated.
