Progress toward HLB-tolerant citrus from conventional plant breeding
The USDA citrus breeding program has numerous cultivated varieties that have been released. USDA-produced varieties are represented in more than 75% of US- grown citrus trees. Like most fruit trees, citrus trees have a fruit-producing part (scion), which is grafted onto a mostly underground part (rootstock). Dr. Ed Stover focuses on developing new scions using conventional breeding approaches. The resulting fruit produces seeds that germinate and give unique new citrus types.
