Kartonsoort

Kartonsoort refers to a cultivar of the potato plant (Solanum tuberosum) selected for specific characteristics that influence yield, tuber quality, storage, and processing. Seed potatoes are typically propagated vegetatively to preserve the traits of a given kartonsoort, ensuring uniformity across harvests.

Traits and classification of kartonsoorten encompass several dimensions. They can be grouped by intended culinary use (table potatoes for fresh consumption, or processing types for frying, baking, or chips), by maturity (early, mid-season, late), and by tuber characteristics such as skin and flesh color, texture (mealy versus waxy), and storage performance. Breeding aims often include disease resistance (notably to late blight), tolerance to environmental stresses, and stable dry matter content to meet market and consumer preferences.

Cultivation and breeding of kartonsoorten are carried out by plant breeders who conduct comparative trials to assess yield, tuber size distribution, storage life, flavor, and processing quality. After evaluation, successful varieties are released for commercial seed production and distribution. Regional adaptation to climate, soil, and farming practices influences which kartonsoorten are grown in a given area, and many countries maintain programs to promote locally favored varieties while preserving genetic diversity.

Examples and usage illustrate the diversity of kartonsoorten. Notable varieties include Bintje, a classic Dutch table potato with good cooking properties; Nicola, a yellow-fleshed, versatile option for salads and roasting; Russet Burbank, a high-starch type preferred for baking and fries; and Maris Piper, common in the United Kingdom. The choice of variety varies by country and market demand. Proper storage—cool, dark, and humid—helps preserve taste and cooking quality by limiting sugar accumulation and sprouting.

Impact and regulation of kartonsoorten support food security and market diversity. Seed certification and plant breeders’ rights help protect new varieties and ensure true-to-type propagation, while seed-potato programs aim to control disease and maintain stock quality.
