美国Reid种质在中国玉米育种和生产中的作用

The Usage of the Germplasm of Reid in Breeding and Produce of Maize in China

分析了20世纪70年代至今美国Reid种质在中国玉米育种和生产中的研究与应用,结果表明优良玉米自交系5003、U8112、掖478、掖107、铁7922、丹9046等和玉米杂交种掖单2、4、12、13号、沈单7号、本玉9号、成单14、雅玉2号、登海11、郑单958和东单60等对中国玉米育种研究和生产应用产生了重大影响,做出了巨大贡献。其间利用的主要杂优模式为美国Reid与旅大红骨、四平头、Lancaster、美国P78599种质、综合种选亚群和Suwan亚群等。新世纪如何继续沿用原有杂优模式和创建新的杂优模式都值得玉米育种家高度重视,为中国玉米育种和生产再上新的台阶奠定基础。

We have analyzed the research and appliance of germplasm of Reid from 20 centuries 70 ages to present in breeding and produce of maize in china. As a result of fine breeding lines, i.e. shen 5003, U8112, ye478, ye107, Tie7922, dan9406 etc. andmaizehybrids, i.e. yedan2, 4, 12, 13, shendan7, Benyu9, chengdan14, yayu2, Zhengdan 958, Dongdan60 etc. Came in to being great influence and made a huge contribution about breeding study and produce apply of maize in China, Breeding expert of maize took advantage of Reid cross L da Reid cob, sipingtou, Lancaster, P78599, composite subgroup and Suwan subgroup etc. In this period, it is main heterotic patterns to go on utilizing old and founding new ones.
