在小麦育种工作中,对掌握的常用农艺亲本和新引入的一些国外抗源材料进行较为系统的研究,在工作所及的范围内,对这些材料的主要数量性状遗传规律进行分析,对于小麦的杂交育种工作是很有意义的.近几年,北京地区的一些育种单位用京双12号和长丰1号等作为早熟农艺亲本作了不少的杂交组合,也收到了一些效果.在抗源亲本方面,近年中国农科院又从美国等引入了OK系统和HWY1775等新材料,为了对这些新材料与国内早熟农艺亲本杂交后的性状遗传 In the process of wheat breeding, we studied the commonly used agronomic parents and some newly introduced foreign anti-source materials systematically, and analyzed the genetic laws of the main quantitative traits of these materials within the scope of our work. In recent years, some breeding units in Beijing have made many hybrid combinations with early maturing agronomic parents such as Jingshuang 12 and Changfeng 1, and have also received some results. Parents, the Chinese Academy of Agricultural Sciences in recent years from the United States introduced the OK system and HWY1775 and other new materials, in order to these new materials and domestic parents of early hybrid agronomic inheritance
