Genetic resources: the basis for sustainable and competitive plant breeding

Zusammenfassung: | Plant genetic resources are the fuel for breeding, which in the search for higher yield and adapted genotypes, manipulates genes in order to meet the needs of farmers, and especially, of the current market. However, the use of accessions available in germplasm banks is low. Topics discussed in this paper emphasize the importance of plant genetic resources, and warn about problems related to genetic vulnerability; also, they discuss about aspects of costs involved in conservation and suggest recommendations for strengthening the area in Brazil.
Os recursos genéticos vegetais são o combustível para o melhoramento genético, que na busca por genótipos mais produtivos e adaptados, manipula genes a fim de atender às necessidades dos agricultores e, principalmente, do mercado atual. Entretanto, a utilização dos acessos disponíveis nos bancos de germoplasma é baixa. Os tópicos abordados nesse artigo enfatizam a importância dos recursos genéticos vegetais, alertam para problemas relacionados à vulnerabilidade genética, discutem aspectos de custos envolvidos na conservação e apontam recomendações para o fortalecimento da área no Brasil. |
