Abstract

Tubers of 101 clones of 24 potato wild species were screened for accumulation of reducing sugar during cold storage at 4°C
after 3 months of storage. Significant difference in reducing sugar content was observed between and within species. Elite
clones with acceptable limit of reducing sugars were identified from different wild species. Solanum spagazzinii and S.
sparsipilum had more number of clones with minimum reducing sugar content after cold storage. Some identified clones
with less reducing sugars after cold storage were SS Nos. 564-5, 1301-9, 1636-3, 1648-1, 1671-3, 1686-6, 1724-30, 1724-
36, 1724-38, 1724-31, 1724-33, 1725-82, 1725-50, 1725-86, 1725-77, 1725-74, 1725-79, 1725-51, 1725-15, 1725-22,
1725-28, 1725-25, 1725-93, 1725-88, 1725-84, 1725-55, 1725-48, 1725-78, 1725-73, 1725-57, and 1725-90.
