摘要:

玉米Suwan种质抗性好、适应性强、籽粒品质优, 在现代育种尤其是南方玉米育种中具有不可替代的作用。明确Suwan种质优良特性在改良过程中的遗传机制对我国南方玉米生态区的玉米生产具有重要意义。本研究以Suwan 1 (Suwan 1C10)及其衍生群体(苏兰1号C0)不同改良世代为材料, 利用包含5.6万个SNP标记的MaizeSNP50芯片对供试群体进行基因型鉴定。遗传分析发现: Suwan 1群体不同改良世代间的基因组差异片段较少, 仅出现5个, 其中4个出现在第11轮改良世代(Suwan 1 C11), 1个出现在第15轮改良世代(Suwan 1 C15); 苏兰1号不同改良世代间的基因组差异片段相对较多, 共有18个, 其中8个在不同改良世代间稳定遗传; Suwan种质改良形成苏兰1号群体的过程中, 共获得43个Lancaster特异性遗传片段, 其中35个在苏兰1号不同改良世代间稳定遗传。全基因组关联分析共鉴定出16个与穗行数显著关联的QTN, 分别位于第2、第3、第5、第6、第7、第8、第9染色体上, 其中SYN25713和SYN36577位于苏兰1号群体的Lancaster特异性遗传片段内; 共检测到13个控制穗长相关的QTN, 分别位于第1、第2、第5、第7、第8、第9染色体上, 其中PZE-105143697位于苏兰1号群体的Lancaster特异性遗传片段内。该结果为后续全基因组关联研究和分子标记辅助选择等提供了重要的理论依据。

Abstract:

Suwan germplasm with good resistance, strong adaptability and excellent grain quality has played an irreplaceable role in modern breeding, especially in the southern of China. It is important to clarify the genetic mechanism of Suwan germplasm. In this study, modified generations of Suwan 1 (Suwan 1 C10) and its derived population (Suwan-Lancaster 1 C0) were used to be genotyped by using MaizeSNP50 chips containing about 56,000 SNP markers. There was a smaller genome differences among different improved generations for Suwan 1 population, with only five different inherited fragments identified, among which four appeared only in the 11th improved generation (Suwan 1 C11), one appeared only in the 15th improved generation (Suwan 1 C15). For Suwan-Lancaster1 population, among 18 different genetic fragments eight were stably inherited in different improved generations. A total of 43 specific genetic segments of Lancaster germplasm were obtained, among them 35 were stably inherited in different improved generations. Genome-wide association studies (GWAS) showed that 16 QTNs significantly associated with kernel row number were located on chromosomes 2, 3, 5, 6, 7, 8, and 9, respectively, among them SYN25713 and SYN36577 were located in the Lancaster specific genetic fragment of the Suwan-Lancaster 1 population. A total of 13 QTNs related to ear length were located on chromosomes 1, 2, 5, 7, 8, and 9, respectively, among them PZE-105143697 was located in the Lancaster specific genetic fragment. These results provide an important theoretical basis for the subsequent genome-wide association study and molecular marker assisted selection.
