[KM15] Genetic diversity - agriculture plants
Impacts

Key message
Neutral

The share of five most dominant varieties for each species of agricultural plants prevails in the majority of them, with the exception of maize, common wheat and potato. The total number of varieties in production for the stated three groups of agricultural plants from 2008 has declined.

Goals

- maintaining as high as possible biological diversity and diversity of varieties in plant production, which is the basis for food production, and preserving landscape variety, the source of income for survival on farms and is part of natural and cultural heritage.
