The PepMoV has been considered the most frequently detected potyvirus. When it co-infects with CMV or PMMoV, it gives severe impact to total pepper harvest in Korea. Since F1 hybrid that resistant to PepMoV has not been developed, we have developed transgenic peppers using Agrobacterium-mediated transformation with a Hc-Pro gene of the PepMoV. A large number of GM peppers were tested for resistance to the PepMoV, and after consequent self-crossing up to T4 generation, a highly tolerant pepper to PepMoV called T20 was selected. So far, BC4F1 lines have been selected by back-crossing with 4 elite lines through a breeding program. Very recently, based on molecular analysis, we have selected another event, #10-2, which is also resistant to PepMoV. Horticultural difference was investigated for both GM lines, #T20 and 10-2, and no significance was found comparing to non-GM lines.
