Evaluation of heat tolerant potato hybrids for storage at room temperature in Satpura Plateau

Three heat tolerant potato hybrids, viz., HT/93-707, HT/93-727 and HT/92-621 along with two control varieties Kufri Pukhraj and Kufri Lauvkar were evaluated for storage at room temperature (30.938.4OCI) for 75 days at Chhindwara in Chhotanagpur Plateau. Tuber weight loss in heat tolerant hybrids was at par with control cultivars up to 60 days after storage (DAS), while it was significantly lower (11.5%) than controls (13.8 to 14.5) at 75 DAS. Substantial increase in weight loss after 60 DAS could be attributed to higher sprouting intensity in cv. Kufri Lauvkar and higher rottage in cv. Kufri Pukhraj. Heat tolerant hybrids had lower rottage, sprouting and weight loss at 75 DAS, hence had a better keeping quality at room temperature than controls.
