"Breakthrough Accelerates Search for Huanglongbing-Resistant Citrus"

Scientists from ARS and University of Florida have made a genetic discovery that could accelerate the development of hybrid citrus trees tolerant to citrus greening disease and capable of producing orange-like fruit ideal for juice production. The discovery involves identifying a master gene and creating a DNA marker for it, enabling breeders to screen seedlings for desired flavor profiles at an early stage. This research represents a significant step in citrus breeding and could serve as a model for other crop improvement programs.
