Polish 2
Origin
M-9 X Common Antonovka, developed by Dr. S. W. Zagaja at Skierniewice,
Poland.
Influence on Scion Habit
P-2 produces trees that are about 25% of seedling size. P-2 has been
widely used in Poland as an interstem because of its exceptional
winter-hardiness. Cropping efficiency is similar to M-9 Trees on P-2
display good open growth.
Disease Resistance
P-2 is resistant to collar rot and is slightly susceptible to scab and
mildew. P-2 shows resistance to European canker, perennial canker,
silver leaf and crown gall.
Nursery Habit
In the
layers, P-2 is not as straight as P-1 and produces some feathers. It
compares to EMLA 26 in rooting and stooling density. Leaves are dark
green, round with deep serrations. P-2 is non-suckering and produces
good scion growth with numerous lateral branches. Trees on P-2
defoliate early in the fall and break bud late in the spring. No
burrknot tendency.
Horticultural Value
P-2 has excellent winter hardiness, similar to Alnarp 2, and is used as
an interstem on Antonovka seedling in Poland to produce hardy trees that
are M-9 size and can be free standing. Requires a rich soil and is also used
for high density trellis planting with vigorous varieties. P-2 is
precocious and crops in the third year.
