Description: In this study, we identified a new heterotic group (X group) based on an examination of 512 Chinese maize inbred lines. We generated whole-genome sequences of core inbred lines with an average coverage of 17.35X for exploring genome changed during breeding improvement of the X group. We analyzed the IBD segments transferred from the two parents to the X lines. To further identify the genetic factor controlling yield improvement, we conducted QTL mapping from a DH population for key yield-related traits.
