The aim of the present study was to evaluate 19 potato genotypes in a commercial greenhouse in Minadasht, Isfahan, at two levels of full irrigation and deficit irrigation and to introduce superior genotypes based on yield, irrigation water productivity, and economic irrigation water productivty. This study was conducted in split plots and in a completely randomized design including two levels of full irrigation and deficit irrigation, 19 genotypes, and three replications. These genotypes were selected with the aim of producing mini-tubers and using them in breeding programs. A drip irrigation system was used for irrigation, and irrigation management was performed based on the water requirement of potatoes inside the greenhouse. The results showed that the effect of irrigation on the number of tubers per plant, the number of commercial tubers per plant, the weight of all tubers per plant, irrigation water productivity, and economic irrigation water productivity was significant (p<0.01). Also, the effect of genotype on the number of tubers per plant, the number of commercial tubers per plant, the weight of one tuber, the weight of all tubers per plant, irrigation water productivity and economic irrigation water productivity was significant (p<0.01). The interaction effect of irrigation and genotype on all the mentioned traits except the weight of a single tuber was significant (p<0.01). Two indices of the number of commercial tubers and economic irrigation water productivity were considered to determine suitable and unsuitable genotypes. The genotypes AD15, AD50, and AD2 with the number of commercial tubers of 13-17 and the economic irrigation water productivity of 151-206 million Rials/m3were the best choices. The use of selected genotypes in the production of potato mini-tuber can simultaneously improve the economic yield and economic irrigation water productivity.
