The complete coat protein (CP) nucleotide sequences of nine historical (1943-1984) potato virus Y (PVY) isolates belonging to resistance strain groupings Y-C, Y-Z or Y-O, and nine new Australian isolates from potato and tomato were compared with those of 85 others. New potato isolate BL was in resistance group Y-O. On phylogenetic analysis, the historical potato isolates fitted within phylogenetic groups C1 or C2 (Y-C), 'Y-O' (Y-Z, Y-O) or N-Wi (Y-Z), while the new isolates were in phylogenetic groups C1 (tomato) or 'Y-O' (potato, tomato). Substitution of the designation (Y-Q) for the current phylogenetic 'Y-O' grouping is proposed for consideration.
