Fire blight

Susceptible

Crown & Root Rots

Variable screening results, further testing required

Woolly Apple Aphid

Susceptible

Powdery Mildew

Moderately resistant

Hardiness (Midwinter)

Originally released as a more cold tolerant competitor to M.9, later tests have been inconclusive. P.2 is probably among the most cold tolerant rootstock genotypes, but perhaps not in late winter/early spring.

Observations, suspicions, history

There is a conflict between European and American trial results with P.2 - American trials have placed P.2 consistently as a more dwarfing rootstock than M.9, while European trials have generally found P.2 to be significantly larger than M.9. In the Pacific Northwest, P.2 is considered to be competitive with MARK, B.146, and B.491. P.2 is a promising cold hardy genotype. P.2 is very susceptible to fire blight. P.2 is recommended for orchard testing by growers in regions where fire blight is less severe.
