摘要：

The endophytic bacterial community diversities of hybrid maize seeds and their parents were explored by traditional isolation and culture methods. The experimental results showed that hybrid corn Jingke 665, Jingke 968, MC738 and Jingnongke 728 had 2, 4, 5 and 7 OTUs (operational taxonomic units) respectively, and the parents were Jing 725, Jing 92, Jing 724, Jing 2416 and MC01, which contained 2, 1, 3, 3 and 4 OTUs, respectively. The same dominant species of the endophytic bacteria were found in both parents and their offspring. Bacillus subtilis subsp. subtilis NCIB 3610T was the first dominant strain of the progeny Jingke 665, and its parents of Jing 725 and Jing 92. Bacillus megaterium NBRC 15308T was the first dominant species of progeny MC738 and was the second dominant species of its parent Jing 2416. Bacillus subtilis subsp. subtilis NCIB 3610T was the third dominant species of the progeny Jingnongke 728 and was the second dominant species of its parent Jing 2416. There was a common dominant genus between the progeny from the common parent. Bacillus were the common dominant genus in hybrid maize Jingke 665 and Jingke 968, which both had the common father of Jing 92. Bacillus and Micrococcus were the common dominant genus in hybrid maize Jingke 968 and MC738, which derived from the common mother Jing 724. Bacillus and Micrococcus were the common dominant genus inhybrid corn MC738 and Jingnongke 728, which were both from the common father of Jing 2416. Therefore, there was a genetic correlation between the parental progeny of maize, and there was also a correlation between endophytic bacteria of hybrid corn with the same parent. © 2020, Editorial Department of Journal of Food Science and Technology.
