在掖单12号杂交玉米制种过程中,因其父本自交系81515雄穗小花花丝过短,花药不能畅快吐出颖壳,花粉量小,散粉不足,往往造成母本受粉不良,制种产量较低。为了解决这一问题,从1989年起,我市博爱县种子公司的技术人员对掖单12号的亲本478、81515夏播生育期进行了系统的观察研究,现已掌握了其生长发育规律。并将这些规律应用到杂交制种生产中,取得了良好的效果。1991年,我市博
In the process of Yedan 12 hybrid corn seed production, anthers could not spit out the husks because of the filial filaments of their male parent inbred line 81515, the amount of pollen was small, Low yield.
