Summary The objective of this study was to investigate the response to selection for chip colour after harvest (CH), storage at 12.8°C (CR) and at 3°C (CC) in three hybrid populations. Population 1 was derived from crossing ND860-2 (cold chipper) with F58089 (regular chipper), Population 2 was obtained from crossing ND860-2 with Russette (nonchipper), and Population 3 was derived from crossing Russette with F58089. Eighty-five to ninety-six random clones for each population plus ten check cultivars were planted in 1991 at two locations in East Canada. For CH, Population 3 had the highest predicted gain. No genetic variation for this trait was detected in Population 1. The potential genetic advance by selection within Population 1, as measured by the predicted mean of the selected clones, however, was similar to the others because Population 1 has a higher mean. For CR, Populations 2 and 3 had similar expected response estimates. Population 1 had no genetic variation for CR but showed similar potential advance to Population 2 and higher than Population 3. For CC, Population 2 had the highest predicted gain. The predicted means of selected clones of Populations 1 and 2 were higher than that of Population 3. Consequently, Populations 1 and 2 had greater potential for improvement for CC than Population 3.
