Abstract
Pepper accessions that were selected for resistance to bacterial wilt were evaluated for their resistance to two strains (Rs004 and Rs005) in 2010 and three strains (Rs005, Rs006, and Rs010) in 2011 of the bacterial wilt pathogen, Ralstonia solanacearum. KC00121, KC00355, KC00359, KC01051, KC01052, KC01260, KC01261, and KC01263 showed a similar level of resistance as MC4 (KC00350), the worldly known source of resistance. Nuclear genotypes of restorer-of-fertility locus for the cytoplasmic male sterility of the accessions were identified by crossing them to a cytoplasmic male sterile line, Punggok-A (Srfrf) and examining the male fertility of the resultant F1 plants. KC00355, KC00359, KC01051, KC01052, KC01260, KC01261, and KC01263 were found to be maintainers of the Nrfrf genotype, whereas KC00121 was a restorer of fertility with the N(S)RfRf genotype.
