Markies: The Agrico Maincrop Variety Built for Fries and Crisps

Not every potato variety needs a dramatic backstory to matter. Markies is a case in point: it doesn't have Belgium's export numbers or Egypt's four growing seasons attached to its name, but it's one of the varieties quietly underpinning Europe's french fry and crisp supply chains. Bred by the Dutch company Agrico as part of its "Agrico Originals" line, Markies has built a reputation as a proven, reliable maincrop variety — the kind processors keep coming back to rather than one that makes headlines.

Markies is classified as a maincrop variety, maturity class 4 — meaning it sits in the later-maturing end of the spectrum, giving it a full season to build the tuber size and dry matter that processors want. Agrico's own datasheet describes it plainly as a "high yielding, all-round maincrop potato variety for French fries, crisping, fast food." Above ground, the plant has blue-violet sprouts and white flowers, with foliage development rated quite fast initially (7/10) and good by the end of the season (8/10), and firm foliage (8/10) that holds up through the growing period. Berry production is below average (6.5/10), which is a minor agronomic detail but one Agrico tracks as part of its standard variety characterization.

The tuber itself is oval-long in shape, with regular shape (7/10) and regular size (7/10) — consistency that matters when a processing line is cutting thousands of tubers into uniform strips. Skin is yellow with a good finish (7/10), and the flesh is light yellow (6.5/10). Tuber size runs quite large (7.5/10), and tuberization — how the plant sets its tubers — is rated average (6/10). Dormancy is also average (6.5/10), which factors into how long seed and ware stock can be held before sprouting becomes a concern.

The numbers that matter most to a fry or crisp plant are dry matter and cooking behavior, and this is where Markies earns its place. Dry matter content sits at 22.8%, with an underwater weight of 427 and a TGA level of 3.4. Cooking type is classified as floury (BC). Agrico rates fries quality as excellent (8/10), dry matter distribution as good (7.5/10), and crisping quality as good (7/10) — in other words, Markies performs well across both of the two biggest processed-potato categories rather than being optimized for just one. Agrico's marketing material summarizes this as "consistently high processing yields," and describes the variety overall as "proven and reliable."

Markies' resistance profile is a mixed picture, which is typical for an older, widely proven variety — strong on some fronts, a genuine liability on others. Its standout strength is golden nematode: Markies is rated resistant to Ro 1/4 (9/10), a significant advantage in fields with a history of potato cyst nematode pressure. It's also rated slightly to not susceptible to fusarium (8/10). Virus resistance is moderate — slightly susceptible to leaf roll (7/10), Yn (7.5/10), and Yntn tuber symptoms (7/10). Late blight resistance is also moderate, at slightly susceptible for both foliage (6.5/10) and tuber (7/10).

The weak points are clear from the same datasheet: Markies is rated very susceptible to spraing (4/10) and very susceptible to powdery scab (3.5/10), and susceptible to common scab (5/10) and wart disease strain F6 (5/10). Growers working land with a history of any of these pressures need to weigh that against the variety's processing strengths.

A few handling sensitivities are worth knowing before harvest. Markies is rated sensitive to harvest damage (5/10) and quite sensitive to secondary growth (6/10) and to discoloration after cooking (6/10), with slight sensitivity to growth cracks (7/10) and to raw discoloration (7/10). On the positive side, it's rated slightly to not sensitive to black spot / internal bruising (8/10) — a meaningful plus for a variety that has to survive mechanical handling on the way to a processing line. It's also only slightly sensitive to metribuzin, both pre-emergence and post-emergence (7/10 each), giving growers some flexibility on weed control timing. Despite the handling sensitivities around harvest, Agrico describes overall storability as good to excellent, supporting the variety's reputation for consistently high processing yields well after harvest.

Agrico positions Markies as a globally proven variety, grown across Europe and beyond. It's particularly well established in Western Europe, with additional strongholds in Eastern Europe, the Far East, and other traditional markets where Agrico has long-standing distribution. In company video material, Agrico product manager Adrie Omtzigt highlights the same combination that shows up throughout the variety's technical data: good yield, excellent storability, and good baking quality.

None of this makes Markies a flashy variety. What it is, according to its own breeder's data, is a dependable, dual-purpose workhorse — the kind of potato that keeps a fry line and a crisp line both running well, season after season, without needing to be the centerpiece of anyone's marketing.
