Abstract: The experiment was conducted in Randomized Block Design (RBD) with three replications at Potato Research Station, Sardarkrushinagar Dantiwada Agricultural University, Deesa during rabi 2017-18. The crop was harvested at 90 days after planting. The analysis of variance revealed that mean sum of squares due to genotypes were found highly significant for all the traits. This is proved that the existence of tremendous variability in the experimental material for different traits. However, from tuber yield point of view, MS/9-2196, J/7-37, K. Ganga and K. Anand were elite genotypes based on per se performance. The genotypes, K. Lauvkar, K. Sindhuri and DSP-7 exhibited low physiological weight loss, while genotypes, K. Surya, MS/12-655 and K. Ganga had low loss due to rottage on weight basis. Thus, these genotypes may be considered as good for storage ability at room temperature storage condition. The high heritability along with high genetic advance in plant height, leaf area, fresh weight of tops per plant, number of tuber per plant, tuber yield per plant, average tuber weight, physiological weight loss, loss due to rottage on weight basis, loss due to rottage on number basis and total weight loss, suggested that genotypic variation for the characters is probably attributed to high additive genetic effect and selection would be rewarding based on phenotypic performance.
