摘　　要：按 Ｇｒｉｆｆｉｎｇ双列杂交设计，对玉米两雄穗性状穗颈长和雄穗重进行了研究，结果表明，雄穗是重要的产量影响因子，在产量形成的总变异中其作用可占到３７．４％，文中同时表述了在Ｍａｔｈｅｒ加──显模型下两雄穗性状的遗传表达特点及可供参考的育种对策。According to Griffing diallel crossing design to study two male spike characters and the yield per plant of maize, the research indicated that the lenth of male spike nike and the weight of the male spike may have important role to yield, and 37.4% actors were declared in tatal variaty of the yield. In this paper, the genetic expression on the basis of Mather's additive-dominance model and the countermeasure as a breading reference were showed.
