Effect of storage temperature on the development of internal sprouts and little potatoes in some potato cultivars

Storage of seed tubers of six potato cultivars at 4°C for six months, followed by two months at 20°C with three desproutings at 30 days interval led to the development of “little potatoes” in all the six cultivars studied. Internal sprouting and internal tubers were observed in a few tubers of Kufri Sindhuri while the other five cultivars showed no internal sprouting and internal tubers. Formation of “little potatoes” was induced on dark and light grown sprouts of physiologically old tubers by giving low temperature treatment.
