La Kennebec potato It is one of the most appreciated and recognized varieties worldwide, especially in Europe and North America, thanks to its culinary versatility, its excellent adaptation to different types of soils and climates, and its great resistance to disease. Native to North America, its fame has spread especially to regions like Galicia, where many mistakenly identify it as the only Galician potato.
Origin and history of the Kennebec potato
The Kennebec comes from a crossing of American varieties Produced by the United States Department of Agriculture. It was developed to combine the best agronomic and culinary characteristics of its parents. Its name comes from the Kennebec River, located in the state of Maine, a farming region with a long tradition of potato growing, and is also linked to the culture of the Abenaki tribes in the region.
Over time, the Kennebec potato has earned a prominent place in international markets and cuisines, expanding its cultivation beyond North America, reaching European territories such as France, Belgium, the Netherlands, and, notably, Spain. The fields of Galicia, mainly in the regions of A Limia (Ourense) and Prades (Tarragona), have adopted this variety to the point of having Protected Geographical Indication (PGI) in both regions.
Its popularity is such that in Galicia it is considered the benchmark for the preparation of traditional dishes such as Galician octopus or the iconic cachelos. However, it's worth remembering that other important varieties are also produced in Galicia (Monalisa, Agria, Frisia, etc.)
Morphological and agronomic characteristics of the Kennebec potato
- Size and shape: Kennebec tubers are generally large, oval, and regular in shape, making them easy to peel and prepare in the kitchen.
- Skin: It has a thin, smooth, light yellow skin with shallow eyes. When sold unwashed, its appearance may be darker and rougher to the touch.
- Pulp: Pure white in color, very firm and compact. It is a potato with a high starch content and low water content, which gives it its characteristic texture and makes it a prime choice for multiple culinary uses.
- Foliage and plant: The plant is upright, large in size and has thick stems, light green in color and very large, stiff and wide leaves, with slight pubescence on the central veins.
- Flowering: Sparse, with small inflorescences and few white flowers.
Most relevant agricultural characteristics
- Maturation: It is a variety of mid-early to mid-late cycle, which allows for good yields in both early and seasonal crops.
- Performance: Excellent, with generous harvests and tubers of very uniform size.
- Resistance: Stands out for its disease resistance such as web necrosis (leaf curl virus), downy mildew (Phytophthora infestans), the black leg (Erwinia carotovora), the black wart (Synchytrium endobioticum) and various viruses (S and X). It is moderately susceptible to other diseases such as common scab, rhizoctonia, fusarium dry rot, late blight and pink eye, and somewhat more susceptible to verticillium wilt.
- Adaptability: It can be grown in a variety of climates and different soils (loam, sandy loam, even in mountainous areas).
- Drought tolerance: Its powerful foliage covers the ground well and withstands dry periods, making it suitable for gardens with different environmental characteristics.
Nutritional value of Kennebec potato
The Kennebec Potato It is low in sugars and fats, with a high carbohydrate content, especially in the form of starch. It provides vitamins (C, B1, B2, B4, B6), minerals (potassium, phosphorus, magnesium), and also has notable antioxidant properties. It is an excellent source of energy and micronutrients, ideal even for low-fat or low-sugar diets.
Its starch-rich composition makes it especially suitable for purees, creams and soups It has a smooth and creamy texture. Its firm flesh makes it a favorite for frying, as it absorbs little oil, maintaining a crispy texture on the outside and a creamy texture on the inside.
Growing the Kennebec potato
El Kennebec cultivation It is accessible to both professional farmers and small gardeners due to its adaptability and hardiness. The main factors and tips for planting and management are detailed below:
- Planting time: It can be sown for much of the year, although the early or mid-spring is optimal for most regions.
- Ground: It prefers loamy or sandy loam soils well nourished with organic matter. It's important to avoid waterlogged soils to minimize the risk of rot.
- Optimal pH: Between 5 and 6,5 for tastier, better-textured potatoes.
- Land preparation: Deep tillage and pre-fertilization with mature compost or well-rotted manure are recommended.
- Planting distances: It is advisable to leave 60-80 cm between rows and 30-50 cm between plants. The ideal planting depth is about 8 cm to promote proper tuber development.
- Germination: It can be germinated outside the ground or directly sown. For the first 3-4 weeks, avoid excessive humidity and heat to prevent rot.
- Irrigation: Moderately at first, increasing the dose only when the plant forms new tubers. It's important to maintain a constant level of soil moisture, but avoid waterlogging.
- Reproduction: In addition to traditional planting, you can use your own harvest for the next season by selecting the best tubers as seed.
- Harvest time: Ideally, when the plant is flowering, uproot the plant and carefully stir the soil to extract the ripe tubers.
Most common problems and diseases
- Resistant diseases: The Kennebec is not very sensitive to Phytophthora, to virus A and has good resistance to virus Y.
- Diseases to watch out for: Although it is moderately resistant, it is advisable to monitor for the presence of common scab, rhizoctonia, dry rot and verticillium wilt, as it may be susceptible under unfavorable conditions.
- Pests: The most common pests are nematodes and some insects specific to potato crops. Maintaining good agricultural practices and crop rotation helps minimize risks.
Conservation and storage
Once harvested, the Kennebec potato should be stored in a cool, dry place protected from direct sunlight, preferably in breathable bags (and never in plastic bags) to prevent premature germination and the appearance of fungi. Thanks to its low water content, Kennebec keeps very well for weeks under these conditions, making it ideal for both home consumption and sale.
Culinary uses of the Kennebec potato
- Special for frying: For his low proportion of water, Kennebec potatoes absorb less oil when fried, resulting in a texture crispy on the outside and creamy on the insideThey are ideal for preparing high-quality fries, chips, bravas, and side dishes.

- Facing Agria: Agria is the queen for frying thanks to its compact texture, but Kennebec offers a more delicate flavor and greater versatility, especially for stews and roasts.
- Other varieties (Red Pontiac, Spunta): Kennebec maintains its texture better during cooking and adds creaminess to stews and broths, making it one of the most highly rated varieties for any home or professional use.
Additional Tips for Growing Kennebec
- Seed preparation: Select healthy tubers, free of damage and rot. You can cut the tubers if they're very large, ensuring at least two or three holes per piece.
- Crop rotation: Essential for reducing the buildup of pathogens and pests. Avoid repeating the crop in the same plot for at least two or three consecutive years.
- Irrigation control: Avoid excess moisture in the first few weeks to prevent seed rot. Afterward, keep the soil slightly moist while the tubers develop.
- Subscriber: Add organic matter at least once per season. If growth is poor or the plant's greenness is poor, you can supplement with a fertilizer rich in potassium and phosphorus.
- Manual harvesting: It is preferable to maintain the quality of the tuber and avoid damage to the skin, which can shorten the shelf life of the product.
- optimal storage: Keep potatoes in a dark, well-ventilated place, away from moisture and direct sunlight to preserve their freshness.
