Pitaya is renowned for its delicious taste, high nutritional value, and economic as well ornamental appeal. Breeding new pitaya varieties can boost returns by appealing to consumers with diverse morphological traits. However, the genetic basis underlying key traits in intergeneric hybrids of has yet be fully understood. This study investigates dynamics flower, fruit, stem traits, including segregation patterns a mixed inheritance model major polygenic an hybridization between ‘Honghuagqinglong’ (HHQL) (Hylocereus stenopterus) ‘Heilong’ (HL) (Selenicereus grandiflorus). The identified normal or skewed, distribution seven floral, fifteen five indicating their quantitative nature governed multiple genes. Specifically, flower size color exhibited hereditary bias towards ‘HL’ characteristics, while ‘HHQL’ significantly influenced coloration fruit peel pulp. Fruit weight total soluble solids (TSS) content decreased, whereas broader thicker dimensions fewer thorns. offers valuable insights into variation influence genes on hybrids, providing useful reference parental selection breeding programs.
