Abstract: In this research,a recombinant inbred lines (R1Ls)population including 183 lines derived from a cross ofX178 and B73 through the sigle seed descent method was used to analyze the genetic conferring resistance toSCMV.The results showed:certain resistance variations appeared between family lines,part of these family lines possessbetter disease resistance character than their parents lines,therefore this population is an ideal germplasm resource of dis-ease resistance breeding to maize SCMV.Rpulation average susceptible rate close to parents lines level,family lines dis-tribution reached nomal distribution during seedling stage and elongation period,this means scmv resistance appears to begenetics of quantitative characters;family lines reached skew distribution during anthesis and grain filling,and susceptibleplants increased,through analysis,we considered there are 2-3 major scmv resistance genes in X178 germplasm duringlater growth stage,and these genes expressed disease resistant character mainly through additive effect of favorable genes.
