Progress in Developing Improved Citrus Rootstocks to Mitigate HLB

Josh McGillHLB Management, Research, Rootstocks

By Jude Grosser, Manjul Dutt and Fred Gmitter Exploiting citrus genetic diversity is the key to defeating HLB. Plant species have survived for millennia with evolving, hostile pathogens. This is possible through natural selection within genetically diverse populations. Tolerant or resistant individuals survive and intermate, get through the bottleneck, and the species evolves. Current citriculture is based on extremely limited …

Evaluation of Citrus × Microcitrus Hybrid Scions

Josh McGillResearch, Varieties

By Ute Albrecht, Anas Fadli and Chandrika Ramadugu Most commercially available citrus scion cultivars are highly attractive to the Asian citrus psyllid and susceptible to HLB.
