The accurate orientation of breeding target is an important link in top-level design of breeding,and the construction of excellent breeding base population is the key to determine the success or failure of breeding results.According to the actual situation of maize production in Huang-Huai-Hai region,taking the domestic germplasms as the basis,the domesticated foreign germplasms as the core,and the hybrid combination mode as mean,the inbred lines JS151040 and JS161137 with high combining ability and strong disease resistance were bred.Furthermore,JS151040 and JS161137 were crossed to create the novel maize variety Sukeyu 076,which is appropriate for planting in the Huang-Huai-Hai region.
