CHARACTERISTICS: The variety has main season maturity. Yielding
ability is medium to high. This variety first gained prominence
in the forties
and maintained its position of major importance through the 1970's.
During this time, it was the major white-skinned variety in the
Northeast because of its consistent performance. Katahdin is
Plants are medium in size, growing slowly at first,
then developing rapidly with a somewhat open canopy. Stems, leaves,
and petioles are dark green with slight purple pigmentation in the

abundant and fertile. For this reason and for its desirable characteristic,
Katahdin appears in the pedigrees of many North American varieties.
Tubers are round to oblong with buff, smooth skin and creamy white
flesh. Lateral eyes are shallow and apical eyes are moderately deep.
Specific gravity and cooking quality are medium. Dormancy is medium.
STRENGTHS & WEAKNESSES: Katahdin
is susceptible to scab and resistant to mild mosaic, net necrosis
and brown rot. It does not have a high degree of resistance to other
major diseases, but neither is it especially susceptible to them.
Tubers develop high in the hill and are subject to greening. Tubers
are seldom misshapen, but may be irregular in shape under some growing
conditions. The variety acquired its popularity because of its consistent
performance under a wide range of conditions.
