Fusarium wilt poses a serious threat to the global banana industry. Since cultivated Cavendish bananas are triploid, conventional cross breeding is extremely difficult, making mutation breeding an important approach for developing resistant germplasm. However, in mutation breeding, the genetic background of newly created materials is difficult to evaluate rapidly, and the resistance mechanisms of materials obtained through different breeding strategies are inconsistent. In particular, whether derivative selection affects disease resistance remains largely unexplored. In this study, we systematically compared the effects of de novo mutagenesis and derivative selection on the genetic background and disease resistance of banana using whole genome resequencing and transcriptome sequencing.
