【摘要】 从春小麦优良品种“东农120”的育成中证明,选育出综合性状优良的小麦品种是完全可能的。“东农120”不仅抗多种病害,而且高产又质佳。它的育成是在正确育种目标指导下,采用复合杂交,以逐步达到综合多方面的优良性状;并对杂种后代的选择是在促进选择性状易于表现和鉴别的条件下,根据各性状遗传性稳定的早晚按世代分先后;根据育种目标的主次分前后,采取选择性状由少到多,逐步达到全面综合选择的方式。说明这些措施对选育出综合性状优良的品种是十分有效的。更多还原

【Abstract】 The development of the good spring wheat cultivar“Dongnong 120”showed that it was possible to develop a good spring wheat cultivar with multiple desirable characters.“Dongnong 120”is characteried by complex resistance to diseases,high yield and good quality.In order to accumulate different desirable characters,“Dongnong 120”was developed by complex hybridization under the guidance of correct breeding aims.Selection was conducted under conditions where the characters to be selected could be fully expressed and easily evalu- ated.Selection of character was performed in different progenies according to their stability and importance.Selection was first limited to few characters, then increased to more and at last all desirable characters were synthesized together.The result showed that these techniques were effective in developing spring wheat cultivar with multiple desirable characters.更多还原
