Range of colour intensities in the petals of progeny compared with parents. The progeny of all four Actinidia families making up the experimental population showed a range of intensities in anthocyanin expression in their petals. While some red petal genotypes had flower petals that were paler than their F₁ hybrid parent, or A. eriantha, many had much darker red petals. There was a constancy of petal colour within vines. The concentrations of colour compounds were recorded as mg.g^-1 fresh weight of petal tissue. Each progeny genotype was identified by its field position with orchard block number, row number and bay position giving a unique identifier. Parental genotypes may be identified by their field position as described, or their accession number in the germplasm resource.
