Avocado genetic resources across the globe are currently main-tained ex situ in field repositories due to its recalcitrance (Alcarazand Hormaza, 2009), and the unavailability of an alternate storagemethod. Field repositories have the advantage that researchers canphysically evaluate and characterise the accessions for parameterssuch as yield, tree height and disease resistance (Barrientos-Priegoet al., 1992; Benz, 2012).
