The Citrus Breeding Program of Embrapa Cassava & Fruits have been generating hybrids for using as rootstocks, which need to be evaluated in relation to behavior in the natural infection with local strains of Citrus tristeza virus, CTV and the presence of symptoms of flaking eruptive (Bahia Bark Scaling disease - BBS). This study presents the results of the evaluation of 141 hybrids (nucelar seedlings and grafted in rootstocks) stated in the experimental area of Embrapa Cassava & Fruits in the Southern Recôncavo of the states of Bahia. Severity of stem pitting of CTV and BBS symptoms were evaluated by using a rating scale. It was used serological method of ELISA (indirect method) to detect the presence of CTV and RT-PCR. The hybrids evaluated were classified as immunes, tolerant and intolerant to CTV Most of the hybrids that showed symptoms of BBS had a mandarin as parental.
