Characterization and inheritance of the crinkle-leaf trait in peach and peach-almond hybrids.

The crinkle-leafed peach accession P85-111 was used in a series of hybridizations with normal-leafed peaches and almonds to develop F1 and F2 hybrid populations. This discrete morphological leaf condition is characterized by having fewer serrations per unit length of leaf margin, thicker and wider leaf blades and reduced lengths of petiole, stipule and leaf blade as compared with the normal-leafed condition. The crinkle leaf phenotype was not observed in any of the 133 F1 hybrids examined. In the eight F2 hybrid populations utilized in this study, seedlings segregated in a 3 normal-leafed: 1 crinkle-leafed ratio. These segregation ratios indicate that the crinkle leaf characteristic is controlled by a single gene, with the crinkle leaf phenotype being homozygous recessive. Peach and peach-almond hybrids having this characteristic appear to have normal vigour and fertility as compared with normal-leafed siblings. The symbol CL/cl is proposed for this distinct morphological character.
