Two potato parental lines that have been released by the Plant Breeding and Acclimatization Institute, Mlochow Research Center (Poland) in 2002 are outstanding in cold-sweetening resistance. Both clones M-62774 and M-62805 showed low accumulation of reducing sugars in tubers directly after storage for 4 months at 4 deg C. They had medium to high yielding ability, satisfactory tuber appearance, increased starch content and high resistance to potato virus Y. M-62774 had light chip colour and good stability of this trait over four years at three storage treatments (8 deg C, 4 deg C, 4 deg C + reconditioning), while M-62805 was capable of producing regularly light coloured chips after storage at: 8 deg C and at 4 deg C followed by two-week reconditioning at 19 deg C. Both clones are male and female fertile and have been successfully used in crossing programme
