Descripción de la variedad

Easton, is a french fry processing potato variety. Tubers of Easton are white-fleshed and long to long-oblong with a textured to lightly russeted skin.

While french fry processing is expected to be the primary market for Easton, it also has excellent flavor and is very good boiled, mashed or baked.

Characteristics:

Lightsprout: medium to large, ovoid shape, few root tips, short lateral shoots.
Lightsprout Base: medium intensity of anthocyanin colouration, absent or low to medium proportion of blue in anthocyanin colouration, medium to dense pubescence.
Lightsprout Tip: medium size in relation to base, closed habit, absent or very weak intensity of anthocyanin colouration, medium density of pubescence.
Plant: foliage structure is intermediate type where foliage is half open and stems are partly visible, semi-upright growth habit, mid-season to late maturity.
Stem: low extent of anthocyanin colouration along entire length
Leaf: outline is medium size, openness is intermediate between closed and open, medium to dark green on upper side, high extent and weak to medium intensity of anthocyanin colouration on upper side of midrib, weak presence of secondary leaflets, absent or very low frequency of coalescence of terminal and lateral leaflets.
Second Pair of Lateral Leaflets: small to medium size, leaflet is narrower than long.
Leaflet: absent or very weak to weak waviness of margin, shallow veins, medium glossiness of upper side, glabrous blade at apical rosette.
Inflorescence: medium frequency per plant, medium size.
Peduncle: low extent of anthocyanin colouration.
Flower Bud: high extent of anthocyanin colouration.
Corolla: medium to large.
Corolla (Inner Side): medium to high extent of anthocyanin colouration, weak intensity of anthocyanin colouration, absent or low proportion of blue in anthocyanin colouration.
Tuber: long oval to long shape, white flesh.
Tuber Eye: shallow, yellow at.
Tuber Skin: light beige.

Origin and Breeding History

'Easton' (experimental designation 'AF3001-6) originated from the University of Maine potato breeding program. It is the result of a cross conducted in 2002 between the variety 'Silverton Russet', as the female parent, and the selection designated 'AF1668-60', as the male parent.

The seeds from the cross were planted in a greenhouse during the spring of 2003 and the resulting seedlings were transplanted and grown in a greenhouse at the University of Maine's Aroostook Research Farm, in Presque Isle, Maine.

From these, several of the largest seedling tubers were harvested to create a family of seedling tubers from the cross. This family of tubers was planted in the field during the spring of 2004.

From these, selections were made in the fall of 2004 based on visual characteristics including tuber shape, appearance, size, and yield. Further evaluation of the selections was conducted over a number of years during which the evaluation was more intensive and the plots increased in size and/or the number of locations, so that progressively fewer clones were retained.

Many traits were evaluated including yield, tuber size profile, specific gravity, ability to chip from the field and/or storage, freedom from internal and external physical defects, appearance, maturity, and yield. 'Easton' was one of the selections from 2004 which was retained throughout the selection process.
