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. There are some citrus species, however, that are HLB tolerant or resistant. This may be because they are less attractive to the psyllids and/or because they restrict pathogen proliferation and therefore HLB disease development. …

She said up to 40% of fruit can drop from mildly HLB-symptomatic trees shortly before harvest, …

Floridians Discuss HLB on Australia TV

Ernie NeffHLB Management

A Florida citrus grower and a Florida citrus researcher were quoted extensively in a recent Australia Broadcasting Corporation TV show about HLB. Grower Kyle Story and University of Florida Institute of Food and Agricultural Sciences plant pathologist Megan Dewdney appeared in an approximately 12-minute segment of the show Landline. The segment’s focus was Australia’s effort to keep HLB out of …

Dual-Function Peptide Treats and Prevents HLB

Ashley RobinsonHLB Management, Research

New research affirms a unique stable antimicrobial peptide (SAMP) found in an Australian plant can destroy HLB and help prevent infection. Hailing Jin, University of California Riverisde geneticist who led the research, shared the exciting discovery during the 2021 Florida Citrus Show. The naturally occurring peptide is found in HLB-tolerant citrus relatives, such as the Australian finger lime. The peptide …

Breeding Hybrids With HLB Resistance

Len WilcoxBreeding, California Corner

UC Riverside scientists are working to breed new fruits that are naturally resistant to huanglongbing (HLB). The hybrid fruits will ideally share the best of their parents’ attributes: the tastiness of citrus and the HLB resistance displayed by some Australian relatives of citrus. HLB, also called citrus greening disease, has been detected in California, where 80 percent of the country’s …
