Variety traits

Vigor — Raspberry and Blackberry

Rubus L.

A trait representing the intensity of development of the aerial part and the root system, evaluated by shoot height and diameter, as well as their shoot-forming capacity.

In the reference 13 varieties crop Blackberry, where this is mentioned in the description.

Vigor in Rubus L. is determined by a complex of biometric indicators: shoot height, shoot diameter, and the intensity of shoot formation. In breeding, a scoring scale from weak to strong is used, reflecting the productivity potential and bush architecture.

High vigor, reaching 2.5–3 meters per season in blackberries, requires the use of trellises and thorough pruning. The intensity of bush development directly affects the planting scheme, nitrogen fertilizer application rates, and the labor required for plantation maintenance.
