| Abstract: | Summary The influence of a short tuber dormancy and the subsequent sprout growth of the seed tubers during storage at 4 °C on the
processes related to plant development and tuber formation was investigated in a diploid population with 238 genotypes, its
crossing parents and seven tetraploid varieties. Sprout growth during storage at 4 °C was positively correlated to the duration
of the dormancy period at 18–22 °C, the low temperature prolonging the dormancy period. Results show that the duration of
the dormancy period and the sprouting of seed tubers during storage at low temperature did not have a determinant influence
on plant development, tuber formation or the duration of the plant cycle in this large and highly diverse population of potato. |
