摘要
通过对获奖大豆品种黑河3号、合丰25号和绥农14号的系谱分析,归纳出获奖大豆品种的直接亲本和祖先亲本,总结了这些亲本的来源和类型,梳理出获奖品种培育过程中亲本选择和组配上的共同特点,分析了获奖品种在亲本选配上的方法,直接亲本对获奖品种的遗传贡献率。获奖品种比普通品种含有较多的祖先亲本血缘,遗传基础比较丰富,新育成的获奖品种比早期育成品种更加拓宽了遗传基础。对大豆杂交亲本选配和提高育种工作效率有重要的预测指导作用。
Based on the pedigree analysis of the award-winning soybean cultivars ＇Heihe 3＇, ＇Hefeng 25＇ and ＇Suinong 14＇;, direct parents and ancestors, sources and types of these parents, common features of the parents selection as well as setting in the breeding process of award-winning were sorted out, and the parents selection methods of award-winning and genetic contribution rate of the direct parents to award-winning cultivars were summarized. The results showed that the award-winning cultivars had more ancestors blood, richer and broader genetic basis than ordinary varieties. This study provides a valuable reference to soybean hybrid parents selection and breeding efficiency.
