Varieties
- Monona (Solanum tuberosum)
ORIGIN: Named in 1964 by Frito-Lay, Inc. Bred and selected by the USDA in Maine
from a 1953 cross of Katahdin selfed, by Chippewa selfed.
CHARACTERISTICS: A mid-season maturity variety with medium yields
and widely used for chip processing from the field and from extended
storage. Monona is widely grown in the North Central and Northeastern
areas of the U.S. and in Canada.
Plants are small to medium size with spreading growth
habit. Stems are medium thick and round with green and slightly swollen
nodes. Leaflets are large with pointed tips, medium green and roll
when under stress. Flowers are large and white with abundant pubescence.
Tubers are oblong to ovate, somewhat irregular, flattened with smooth,
light-cream buff skin and white fleshed. Eyes are shallow to medium
deep.
STRENGTHS & WEAKNESSES: Produces
an excellent chip color and will recondition rapidly after cold storage
but specific gravity is low. Monona is resistant to mild and rugose
mosaic, tolerant to scab and Verticillium wilt and is very susceptible
to blackleg. The bright white skin and small percentage of tubers
scoreable against the U.S. No. 1 grade are advantages for tablestock.
The irregular shape, moderately deep eyes and variable yield are
the major disadvantages.
