Pedigree diagram of ‘Chandler’ and other walnut cultivars released by the UC Davis walnut breeding program. The values in parentheses after cultivar names represent coefficients of parentage (COP) of a cultivar with ‘Chandler’. If COP is 0, the variety has no lineage relationship with ‘Chandler’. The pairwise COPs were calculated based on the definitions in[39] and[40]. The cultivars in bold font are parents or ancestors of ‘Chandler’. The percentages of heterozygous loci are in square brackets behind some cultivars.
