Abstract: The present study was conducted at ICAR-Central Potato Research Institute, Regional Station Gwalior during 2007-08 to 2016-17 for 10 years on micro-propagted material multiplied at the station to identify suitable tissue culture/ hi-tech based seed potato production systems using micro-plants, micro-tubers and mini-tubers and performance of seven popular cultivars viz Kufri Lauvkar, Kufri Chandramukhi, Kufri Surya, Kufri Bahar, Kufri Chipsona-1, Kufri Chipsona-3 and Kufri Sindhuri planted during 10 years under these three hi-tech systems for potato breeder seed production. Variation in performance among different varieties for establishment/emergence, mean tuber weight and seed multiplication rate (both by number and weight), percent <3 g tuber (both by number and weight) and tuber yield (m2) were recorded during the study. Kufri Sindhuri, Kufri Bahar and Kufri Surya under micro-plant based, Kufri Bahar and Kufri Surya and Kufri Chipsona-1 under micro-tuber and mini-tuber based multiplication system performed better than other varieties under G-0 conditions for yield attributing parameters. Seed multiplication rate by number was higher in micro-plant system of seed production (5.50) followed by micro-tuber systems (5.31) and mini-tuber (4.43) based system of seed production. Mean tuber weight was higher for mini-tuber system of seed production (22.46 g) followed by micro-plant (15.59 g) and micro-tuber systems (14.62) and showed higher tuber yield i.e 130 tuber/m2 and 3.10 Kg/m2 in mini-tuber based system followed by111 tuber/m2 and 1.74 kg/m2 in micro-plant based system and by 86 tuber/m2 and 1.16 kg/m2 in micro-tuber based seed potato production system. Hence performance of Kufri Sindhuri, Kufri Bahar and Kufri Surya under micro-plant based, Kufri Bahar and Kufri Surya and Kufri Chipsona-1 under micro-tuber and mini-tuber based seed multiplication system was better in 10 years of the study.
