Abstract: The Phalaenopsis cultivar ’Phal.B’ was as the male and crossed with white color ’V 3’ and rose color（’Lanjiu’, ’Double Dragon’ and ’Radiant’） respectively. The floral traits such as tepal color, floral spots, callus color and mid-lobe color of the F₁ generation of the four crosses were observed to investigate the inheritance pattern.The results showed that the F₁ generation of the cross showed mesophilic and hyperphilic dominance in flower color, callus color and mid-lobe color. In terms of flower color inheritance, when ’V 3’ was used as the female, the F₁ generation of the cross was segregated into two types of flower color: white with purple-red spots and pure white flowers, and the F₁ generation of the cross with the three combinations of the rose line as the female had a consistent pattern of flower color segregation with a gradient distribution, segregating into four types: deep purple-red, purple-red flower spots, rose-pink, white. The ratio of fuchsia to non-fuchsia in the F₁ generation of the cross was close to 1∶1, meaning that the fuchsia might be a trait controlled by a single gene, and the deep fuchsia flowers might be caused by the uniform distribution of the fuchsia patch color on the tepals and the superimposed effect of the fuchsia. In terms of the genetic inheritance of flesh protrusions, there was a positive correlation between the flesh protrusions of purple-red color, yellow-backed purple-red patches and flower color. When the tepals were purple-red, the color of the flesh protrusions would show purple-red or yellow with purple-red patches, and the proportion of purple-red flesh protrusions would increase as the purple-red color on the tepals become deeper and the distribution area become larger. In terms of mid-lobe color inheritance, the proportion of subpurple red was less and only appeared in the dark purple-red population. There was a positive correlation between subpurple red mid-lobes and both flower color and purple-red fleshy protrusions.
