HEART OF MINUSINSK

Genetic Potential and Agrotechnics of the Indeterminate Variety

"Heart of Minusinsk" (Serdtse Minusinska) is a variety of folk selection, officially registered through the efforts of V. N. Dederko, A. A. Yabrov, and T. N. Postnikova. This tomato features a powerful indeterminate growth habit that requires mandatory training into one or two stems and trellising. With a vegetation period of 100 to 120 days, it is classified as a mid-season variety, allowing for the maximum realization of its large-fruit potential in both protected and open-field conditions.

Fruit Morphology and Productivity

The core technical value of this variety lies in the combination of high yield (up to 70–100 tons per hectare at optimal planting density) and large fruit size (average weight exceeding 200 grams). The heart-shaped form of the fruit indicates a high concentration of pulp and minimal seed chamber volume. The pink skin coloration is due to a specific set of carotenoids, which directly impacts organoleptic properties—specifically, a higher sugar content and balanced acidity.

Phytopathological Protection

Breeding efforts were focused on increasing the crop's viability. The key advantages of "Heart of Minusinsk" in a production cycle include:

• Genetic resistance to late blight (Phytophthora): reduces the frequency of chemical treatments during epiphytotic periods.
• Resistance to Alternaria (early blight): lowers the risks of damage to the foliage and fruit under high humidity conditions.

These characteristics make this variety a reliable tool for professional agronomists aiming to reduce pesticide load without sacrificing commercial quality.
