Abstract
The present experiment was conducted with two popular potato (Solanum tuberosum L.) cultivars of north-east India namely ‘Kufri jyoti’ and ‘Kufri megha’ with the objective to study the biochemical changes in response to high temperature. Parameters such as total chlorophyll, chlorophyll a/b ratio, proline content, total amino acid content, total soluble sugar content, lipid peroxidation and total superoxide dismutase activity were studied during the growth of the potato crop. The study revealed that high temperature has a significant impact on these parameters. The treatment × variety interaction was found to be significant (p ≤ 0.01) for proline content, total soluble sugar content and superoxide dismutase activity at most of the growth stages, and can be taken as marker traits for selection of heat resistant potato varieties. Variety Kufri jyoti was found to be more sensitive to high temperature leading to significant reduction in crop yield compared to Kufri megha.
