通过对1974～1998年辽宁省审(认)定玉米杂交种的种质基础分析表明:辽宁省玉米杂交种亲本来源主要有改良Reid群、旅大红骨群、Lancaster群、综合种亚群。杂种优势利用模式主要为:改良Reid群×旅大红骨群、改良Reid群×lancaster群、lancaster群×旅大红骨群。基于这一分析,提出适应本省的更高一级的杂交模式配对构建的设想。
Based on the germplasm analysis of the corn hybrids in Liaoning Province from 1974 to 1998, the results showed that the main sources of the parent corn hybrids in Liaoning Province were improved Reid group, Ludahong group, Lancaster group and comprehensive species subgroups. Heterosis utilization patterns are mainly: improved Reid group × Ludahong bone group, improved Reid group × lancaster group, lancaster group × Ludahong bone group. Based on this analysis, put forward the idea of constructing a higher level of hybrid pattern matching in our province.
