Estimating maize genetic erosion in modernized smallholder agriculture.

TAG. Theoretical and applied genetics. Theoretische und angewandte Genetik - 1 Sept 2009

Abstract excerpt

Replacement of crop landraces by modern varieties is thought to cause diversity loss. We studied genetic erosion in maize within a model system; modernized smallholder agriculture in southern Mexico. The local seed supply was described through interviews and in situ seed collection. In spite of the dominance of commercial seed, the informal seed system was found to persist. True landraces were rare and most...
