Sprouting of potato is an undesirable phenomenon which results in weight loss and reduces its marketability. In this research, gamma radiation has been chosen as an effective tool to inhibit sprouting at comparatively higher storing temperature. Potato tubers of Kufri Jyoti variety were exposed to radiation dosages of 100 gray (Gy) and 200 gray (Gy) to study the sprout inhibition phenomenon and physical properties of this horticultural crop. The treated tubers were stored at 6°C, 15°C, and ambient temperature (minimum 17°C and maximum 40°C). The changes in the various physical quality parameters (weight, specific gravity, texture, and colour) were determined after five months of storage. Untreated samples kept in ambient showed very high weight loss of 27.4% and sprout wright of 4.23%. 200 Gy radiation was found to be detrimental for the tubers as discolouration in tubers was observed. The sample treated with 100 Gy radiation dose after 30 days of harvest and stored at 15°C temperature showed best results. Sprout weight and weight loss of this sample were found to be 0.62% and 4.47%, respectively. The peak forces of 1352 g and 12100.2 g were in firmness and shearing test, respectively clearly indicate that the texture of this potato samples were intact. The colour values (ΔL=52.2, Δb=41.2, Δa=7.25) obtained from colorimeter instrument were satisfactory enough to ensure customers’ acceptance.
