Citrus Tristeza virus (CTV) is the most destructive disease of the citrus industry. Hence, a study was conducted to identify which among the different high value citrus seedlings at the scion grove of DMMMSU-NLUC, the most tolerant to CTV is deem necessary. This study was conducted employing the Completely Randomized Design (CRD) with three replications. A total of seventy-five High Value Citrus seedlings and ten control plants were evaluated under an improvised screen house at the experimental farm of the DMMMSU-NLUC, Bacnotan, La Union.
