ORIGIN:
Released jointly by Agriculture Canada and the University of Guelph,
Guelph, Ontario, Canada in 1981. Yukon Gold was selected from
a cross between W5279-4,Katahdin and Norgleam.
It was tested under the pedigree G6666-4Y.
TUBBER:
Tubers are oval,slightly flattened, with yellow-whiteskin and light yellow tuber flesh.
It has shallow, uniquely colored pink eyes.distinguishIing Yukon Gold
from other yellow-skinned, yellow-fleshed cultivars.
CHARACTERISTICS:
Yukon Gold has medium-early maturity,moderate yields,
moderate specific gravity and relatively attractive tuber type. Plants
are medium-large to large and upright. Stems are purplish but are more green in
the upper portion of the plant. Leaf petioles extend downward. Nodes are not
swollen. Leaves have a distinct terminal leaflet with four pairs of primary
leaflets which are largest near the terminal leaflet. Secondary leaflets vary
from two on lower leaves to 6-8 on upper leaves, usually in pairs. The number of
tertiary leaves also increases from lower to upper leaves. Flowers are violet to
light-violet with yellow anthers.
STRENGTHS & WEAKNESSES:
Yukon Gold is resistant to mild mosaic, moderately resistant
to leafroll virus and susceptible to virus Y, common scab .
In some growing areas, hollow heart and internal heat necrosis may be a problem.
Yukon Gold retains the yellow flesh color when baked, boiled or french-fried.
The attractive tubers are well suited for fresh marketing.
Plant establishment is irregular, particularly from basal seed pieces.
Pre-cut or whole seed is used in some areas to improve plant stands
