特优５５９的亲本为盐恢５５９和龙特浦Ａ，该组合具有制种高产的特性。制种高产的策略是：母本保足穗，父本争大穗，主攻异交结实率。相应的技术为：合理安排播期、播差期；培育壮秧；合理安排行比，插足基本苗；加强田间管理；采取辅助措施，提高异交结实率；去杂防杂。 Teyou 559’s parents were Yuhui 559 and Longtepu A, which had the characteristics of high seed production. Seed production of high yield strategy is: mother Paul enough spike, father fight big spike, the main attack rate of outcrossing. The corresponding technologies are as follows: Reasonable arrangement of sowing date and sowing date; cultivating strong seedling; rationally arranging the ratio of lines to reach the basic seedling; strengthening field management; adopting auxiliary measures to increase the rate of out-crossing and seed-setting;
