As part of a breeding program to incorporate the resistance of AC2258 and SCM334 to Phytophthora capsici in 'Chilseongcho', a local pepper variety grown in Youngyang, Gyeongbuk province, an evaluation of the resistance to P. capsici was conducted on generations BC1 through BC5 and BC5F2 using artificial inoculation at the seedling stage. Disease-free plants were recovered even in the BC5 generation and a few BC5F2 lines remained uniformly disease-free. This retention of a high degree of resistance in a backcross program was seemingly attributable to the resistance-conferring genes in the resistance sources. As expected, the BC5F2 plants appeared to recover almost all the horticultural characteristics of the recurrent parent, 'Chilseongcho'.
