The USDA-ARS Malus collection was established mainly with materials from contemporary breeding programmes and was biased towards immediate commercial or breeding utility, rather than genetic diversity per se. A review of the collection found that some species were represented by a single accession and/or had scant passport information, primarily because most Malus wild germplasm is native to Central Asia and China, areas that until quite recently had been impossible for US scientists to visit. Thispaper describes some of the collecting missions undertaken in Central Asia, the first being in 1989 followed by subsequent trips in 1993 and 1995. Some of the problems caused by the breakup of the Soviet Union on the maintenance of apple genetic resources in situ are outlined and some of the opportunities for international collaboration are considered.
