Abstract:The integration QTL map for Sporisorium reiliana resistance in maize was constructed by compiling a total of 22 QTL available for this trait with Genetic Map IBM2 2005 Neighbors as reference.These 22 QTL were found to be located on 9 chromosomes of maize with exception of chromosome 7.Using a meta-analysis method,2 "consensus" QTL were identified on chromosomes 2 and 3 with map interval of 8.79cM and 18.92cM,respectively.The gene and marker sequences within 2 "consensus" QTL were downloaded respectively from website Maize GDB,and 4 positional candidate genes were identified by comparing these sequences against resistance genes of other Poacease by internet software BLASTx.Using a synteny conservation approach based on comparative mapping between maize genetic map and rice physical map,a total of 69 rice and maize resistance genes were projected onto maize genetic map IBM2 2005 Neighbors,and one each rice resistance gene was found in 2 "consensus QTL".The results provided useful information for fine mapping!QTL,gene cloning and molecular breeding for resistance to Sporisorium reiliana in maize.
