目前,矮秆成为小麦育种的一个常规指标,矮秆品种也在各地相继育成.高秆品种易倒伏,矮秆品种易早衰,已被人们在实践中所认识.但是,有关的理论问题还未解决,育种工作者还未能真正做到有的放矢,彻底摆脱盲目性,减少无效劳动,提高育种效果.为弄清上述一些问题,我们进行了本试验. At present, the dwarf has become a conventional indicator of wheat breeding, dwarf varieties have also been bred in various places .Large varieties prone to lodging, dwarf varieties susceptible to premature aging, people have been recognized in practice, but the relevant theoretical issues have not yet Solution, breeders have not really targeted, completely get rid of blindness, reduce ineffective labor, improve breeding effect.In order to clarify some of the problems, we conducted the experiment.
