To introduce CMV resistance to susceptible variety, interspecific grafting between d45-6 (Capsicum annuum) and LS1205 (C. baccatum) was conducted. The graft-progenies, G1 and G1S1 were obtained. Mechanical inoculation with CMV showed that disease index of G1 and G1S1 were significantly decreased, similar to that of the resistant stock. ELISA serological test indicated that resistance of LS1205 and the graft-progenies to CMV was caused by inhibition of virul replication. Further, peroxidase isozymatic analysis revealed that zymotypes of G1 were a summation of those found in the donor plants. This result perfectly fit the theory of gene transformation and reconfirmed the conclusion of mechanism of graft-induced variants.
