Project Type: Reimbursable Cooperative Agreement
Start Date: Oct 1, 2020
End Date: Aug 31, 2023
Rapid screening the advanced hybrids for resistance to CLas under greenhouse conditions to facilitate selection of hybrids with broad spectrum of resistance against multiple CLas isolates.
By participating in the concerted, parallel and coordinated efforts towards developing new HLB resistant/tolerant scion cultivars, ARS will propagate the advanced hybrids on common rootstock, sour orange and/or US 942, and then evaluate their resistance/tolerance against at least two distinct CLas isolates using graft-based assay. The disease index and CLas titers will be determined via qPCR and other measurements.
