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.
