Elucidation of the genetic basis underlying rooting ability in vegetatively propagated chrysanthemum.

ABSTRACT: Chrysanthemum, a globally renowned economic crop, primarily relies on vegetative propagation methods such as cutting for commercial cultivation. However, certain varieties with exceptional ornamental qualities often encounter difficulties in widespread adoption due to poor rooting ability and suboptimal root quality. The genetic underpinnings of rooting ability in chrysanthemum cuttings have remained largely unexplored. This study marks a significant advancement in this field. By evaluating 11 rooting traits across a diverse panel of 188 chrysanthemum genotypes, we found that spray cut chrysanthemums exhibit superior rooting ability compared to other cultivated types and wild species. Selective sweep analysis identified 534 selected genomic regions potentially linked to rooting traits duri
