| Popis: |
Biodiversity is essential for an evolving ecosystem and as a resource for further development of natural products by breeding. At present agriculture is under pressure by the demand for increased crop production and the public anticipation for sustainable cultivation practices. Undeniably, the prerequisite for adaptation of an organism to changing environmental conditions is genetic variability. The answer to the concern that the persistent accumulation of desirable alleles in a few cultivars could erode genetic variability and ultimately impede further improvement, comes from the fields of genetic and epigenetic studies that have revealed a range of mechanisms which result in remarkable variability even in narrow gene pools. |
