Abstract: Maize sterility seed production in maize with many excellences to common Seed production ,it con avoid emasculation by hand, reduce the seed production cost and improve seed quality ,it also can amplify heterosis mostly .Study the characteristics of the parents of heterosis restoring hybrids ST501 and the mainfactor that affects the yield and quality of seed production .Advance the selectivepreference cultivation combination for yields 4500kg to 5250kg per ha. From the preference cultivation combination for yields 4500kg to 5250kg per ha. From themain factor of the quality of the parents ,florescence regulation ,planting densities，prescribed fertilizer supplying, preventing diseases and insects ,artificial pollination ,timely gaining.
