We will search for Finnish features in the global tendency of narrowing the biodiversity, whow national plant breeding in maintaining biodiversity. It is assumed that, at least to some extent, the existence and activities of the national plant breeding institutes maintain agricultural biodiversity in a global context, although plant breeding work itself seems, in practice, to narrow the diversity of nature. The national plant breeding works in a specific climatic and social context in order to produce useful results, i.e. plant varieties for natural conditions, and for the needs of society. Plant breeding activity includes both the elements of nature and society. Plant breeders work with nature and society and have to transform these both to be successful in their work.
Plant breeders have to take into account the needs of human actors.
Actually, plant breeders hold the key to the socialization process of the new varieties. We will explore the social setting of cereal plant breeders and breeding programs in Finland and to evaluate the effect of bred cereal varieties on biodiversity.
