Rangpur citrus group was tested during the present study for the identification of tolerance against huanglongbing. Control of huanglongbing (HLB) disease is necessary around the world to avoid the complete destruction of citrus. Rangpur accessions were graft challenged with huanglongbing positive budwood to study the resistance and symptom expression. Vein yellowing symptoms appeared on Rangpur poona nucellar and tuningmeng nucellar while vein yellowing and blotchy mottle symptoms appeared only on tuningmeng nucellar. Kirumakki nucellar and knorr nucellar expressed no symptoms. Being a drought-tolerant rootstock with less HLB symptom expression, Rangpur rootstock cultivars especially kirumakki nucellar and knorr nucellar may be used to test the production and survival of plant with compatible scion varieties.
