| 为明确优质强筋小麦新品种郑品优9号的分子遗传基础及重要性状功能基因组成，利用小麦50 K SNP育种芯片对郑品优9号及其双亲郑麦366和豫麦34进行分析。结果表明，郑麦366和豫麦34对郑品优9号的遗传贡献率分别为68.26%和31.74%；在不同基因组和染色体水平，双亲对郑品优9号的遗传贡献率差异较大，郑麦366对郑品优9号A、B、D三个基因组的贡献率分别为68.60%、90.98%和27.63%，其中，郑麦366在B基因组染色体上的遗传贡献率均高于豫麦34，除1B染色体外，2B~7B染色体上的遗传贡献率均超过80%。重要性状功能基因组成分析发现，郑品优9号不仅聚合了多个优良品质基因，还携带有与抗病性和农艺性状相关的优异基因。本研究可为郑品优9号在遗传改良和生产中的应用提供理论依据。 |
| 英文摘要: |
| In order to clarify the molecular genetic basis and functional gene composition of Zhengpinyou 9,wheat 50K SNP breeding chip was used to analyze Zhengpinyou 9 and its patents(Zhengmai 366 and Yumai 34). The results showed that Zhengmai 366 provided more genetic contribution to Zhengpinyou 9,with a contribution rate 68.26%,which is higher than that from Yumai 34(31.74%). The genetic contribution rate changes greatly among the different genomes and the chromosome level. The contribution rate of the three genomes from Zhengmai 366 to Zhengpinyou 9 is 68.60%(genome A),90.98%(genome B) and 27.63%(genome D),respectively. The contribution rates of chromosomes in genome B from Zhengmai 366 were all higher than Yumai 34,and expect 1B chromosome,the contribution rates of 2B-7B chromosomes were over 80%.The analysis of the functional gene composition of important traits found that Zhengpinyou 9 not only polymerized several good quality-related genes,but also carried excellent genes related to disease resistance and agronomic traits. In this study,the genetic composition and some important functional gene composition of Zhengpinyou 9 were confirmed,which provides theoretical basis for genetic improvement and production application of Zhengpinyou 9. |
