Abstract
Tubers of two potato cultivars namely Desiree and Kufri Jyoti were categorised into two grades viz. small (8–12g) and seed size (40–45g) were pre-chitted and sprouted and were planted in sand supplemented with Hoaglands macro-nutrient medium at monthly interval to evaluate the impact of seed size on root characteristics. Non-destructive sampling for different observations were made at fortnightly intervals while destructive samplings was done at 30 days interval. From the results of intergrade comparision it was found that plants grown from the small size tubers (8–12g) were taller than those grown from other grades. The seed size tubers (40–45g) performed better than small size tubers in root length, root volume and total biomass.
