60年代和70年代初,美国小麦产区的州试验站及几个商业种子公司便开始了杂交小麦研究,同时在大学里主要进行探索性研究.由于亲本选育的复杂性和大量生产杂交小麦价格昂贵,各州实验站减少了杂交小麦研究的投资.除少数研究外,杂交小麦育种均由商业种子公司和化学公司经营.然而各州的产量试验还在不断提供有用的杂种和品种产量性能的比较资料.70和80年代,CHA(化学杂交剂)的发现和发展给杂交小麦研究带了更大的技术潜力和更多的商业投资.
In the 1960s and early 1970s, the State Experimental Station and several commercial seed companies in the US wheat-producing regions started the study of hybrid wheat and conducted mainly exploratory research in universities. Due to the complexity of parental breeding and the mass production of hybrid wheat Expensive, state labs reduce investment in hybrid wheat research. Except for a few studies, hybrid wheat breeding is run by commercial seed companies and chemical companies, however, state trials are still providing useful comparisons of yield and performance of hybrids and varieties Data. The discovery and development of CHA (chemical hybridization agent) in the 1970s and 1980s brought more technical potential and more commercial investment to hybrid wheat research.
