Determinacy

Determinacy is a genetically determined plant growth habit where development is limited by the formation of a specific number of inflorescences. This trait defines bush architecture, maturation rates, and crop management strategies.

Mentioned in descriptions 12 519 varieties reference book.

Determinacy characterizes a plant's ability to cease vegetative growth after setting a fixed number of inflorescences, terminating in an apical flower cluster. Unlike indeterminate varieties that continue to develop throughout the season, determinate forms are distinguished by their compactness and focus on an early transition to the generative phase.

The trait defines the cultivation strategy by ensuring concentrated fruit set, which simplifies mechanized harvesting. This growth type requires specific agrotechniques, as improper pruning can lead to reduced productivity, while the plants themselves often do not require intensive staking.

The evaluation of determinacy during variety testing is conducted through field observations of plant architecture. Agronomists record the number of leaves to the first cluster, total plant height, and the terminal number of inflorescences on the main stem, classifying the variety on a scale from super-determinate to indeterminate forms.
