Variety traits

Maturity group — hairy vetch

Vicia villosa Roth

There are no standardized maturity groups for hairy vetch. Instead, classification based on development type and phenological indicators of the growing season duration is used.

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

In hairy vetch agronomy, the main classification feature is the biotypic composition. Varieties and populations are divided into spring, semi-spring, semi-winter, and winter forms. The key difference lies in the shoot formation method: winter forms have the ability to develop underground buds, while spring forms develop exclusively through above-ground ones.

The concept of earliness is descriptive and is linked to the total duration of the growing season, which reaches 330–340 days in winter forms, as well as to the time of flowering onset. This trait has practical significance for managing green mass harvest timing and seed production planning, where late maturity can limit yield under conditions of heat and moisture deficit.
