improving the characteristic of inbred line maize resistant to rough dwarf virus disease (MRDV)by directional recurrent selection.We could improve disease resistance of inbred line Maize and resistant level of its corresponding hybrid.the characteristic of MRDV is quantitative character,It controlled by polygene .in general,the resistance gene of inbred line is not homozygous,That is the fundamental of improving disease-resistance the process of directional recurrent selection to inbred line maize is the process of polygene accumulated in singular,And quantitative value increased also.
