Summary: | Black rot of Brassica crops is the most devastating disease which causes substantial yield reduction of cabbagethroughout the world. The use of resistant cabbage cultivars could be inexpensive and effective measure to combat this destructivedisease. We screened cabbage inbred lines for black rot disease resistance through bioassay and identified some novel lines that showedrace-specific resistance to Xanthomonas campestris pv. campestris (Xcc) races. The pathogenicity test revealed that out of 27 cabbagelines, one (SCNU-C-4074), six (SCNU-C-3631, SCNU-C-3637, SCNU-C-3639, SCNU-C-4072, SCNU-C-4073 and SCNU-C-3273),two (SCNU-C-3273 and SCNU-C-4118), two (SCNU-C-3270 and SCNU-C-4118), two (SCNU-C-3470 and SCNU-C-41148) and four(SCNU-C-107, SCNU-C-3270, SCNU-C-3470 and SCNU-C-4059) were shown to be resistant to Xcc races 1, 2, 3, 5, 6 and 7,respectively while none of these showed resistance against race 4. Furthermore, these resistant and susceptible lines were evaluated bypreviously reported molecular markers for black rot resistance. The molecular screening results were also revealed the existence ofrace-specific resistance in these cabbage lines. This result will help Brassica breeder to develop race-specific black rot resistant cabbagecultivars. KCI Citation Count: 1 |
