COROLLA

Technological Profile and Morphology

The 'Korolla' variety is a result of selective breeding by the N.I. Vavilov Research Institute (VIR), engineered for stable production under temperate climatic conditions. The biological potential is built upon balanced vegetative mass, enabling the plant to form a dense head within a condensed timeframe.

Performance Parameters

A critical node in the production cycle is the period of technical maturity. The 60-70 day window from transplanting classifies this as a mid-early variety. Key technical specifications include:

• Head Shape: Round-oval, facilitating uniform tissue density distribution.
• Marketable Head Weight: 2.0-3.0 kg, an optimal parameter for standard logistics packaging and retail supply chains.
• Pigmentation: A deep dark-green hue, indicating high chlorophyll content and efficient plant metabolism.

Agronomic Value and Application

The morphological design of 'Korolla' positions it as a versatile tool for growers. The variety’s ability to maintain marketable quality during processing is paired with high competitiveness in the fresh market. The dark-green coloration and dense internal structure provide superior handling resilience during transport and extended shelf life, which is critical for minimizing retail losses.

This selection relies on a genetic base adapted to regional climatic realities, mitigating risks associated with plant reactions to typical mid-season temperature fluctuations. It represents a balanced choice for farms requiring predictable yields and consistent product condition.
