Research and adoption of biotechnology strategies could improve California fruit and nut crops
California’s fruit and nut tree crops represent one-third of the state’s cash farm receipts and 70% of U.S. fruit and nut production. Advances in crop biotechnology and genetic engineering could help protect these valuable crops from pests and diseases and improve productivity. However, due to the difficulty of genetically engineering woody tree crops, as well as intellectual property concerns,...
