Abstract: A trial to assess the performance of potential french fry clones developed at the Potato Research Centre of Agriculture & Agri-Food Canada, Fredericton was conducted during 1998 and 1999. A total of nine clones from the 1998 (AR 98) Accelerated Release Program were evaluated during 1998-1999 and an additional five clones from the 1999 (AR 99) Release were tested in 1999 only. Only two AR 98 clones (AR98-28, AR98-46) produced lower total yields than the controls Shepody and Russet Burbank and only AR 98-28 had a lower marketable yield. AR 99-24 produced a higher total yield than the controls and all AR 99 clones were equal for marketable yield. All AR 98 clones produced equal specific gravities and all AR 99 clones produced higher specific gravities than the controls. Four AR 98 clones had a length-to-width ratio lower than Shepody and only AR 99-42 was slightly better than Shepody. In general, most clones produced good french fry color from storage but AR 98-28 and AR 98-73 did produce lower french fry scores late in the 1998-1999 storage season.
