Abstract :Potato seedlings of various potato genotypes free from the following viruses PVS insert ignore into journalissuearticles values(potato viruses S);, PVX insert ignore into journalissuearticles values(potato viruses X);, PVY insert ignore into journalissuearticles values(potato viruses Y);, PLRV insert ignore into journalissuearticles values(potato leafroll virus);, PVA insert ignore into journalissuearticles values(potato viruses A); and PMTV insert ignore into journalissuearticles values(potato mop-top viruses); were obtained via meristem culture and they were increased in vitro. Seedlings were grown in the greenhouse and mini tubers obtained were tested in the seed bed and in the field trials. When the results of greenhouse experiment were evaluated: clone Nif-1 was found to be high for single tuber number insert ignore into journalissuearticles values(3.0);. Clone 6/7-1 had high means as compared to the remaining for single tuber weight insert ignore into journalissuearticles values(5.2 g); and single plant yield insert ignore into journalissuearticles values(14.5 g);. The highest mini tuber number was obtained from Clone 6/7 in seedbed experiment. Also Hermes-1 had higher means for single tuber weight and Clone 122-1 had the higher means for plant yield and plot yield than that of other clones. Clones Atlantic-2; 3 and 1 insert ignore into journalissuearticles values(5.8 cm); had high tuber width and clone Hermes-1 and 2 insert ignore into journalissuearticles values(6.6 cm); had the highest means for tuber length in the seedbed trial. Based on the results of field experiment the highest minituber numbers were obtained from Clone 6/7-2 insert ignore into journalissuearticles values(10.7); and Clone 6/7-2 insert ignore into journalissuearticles values(10.3);. Atlantic-1 insert ignore into journalissuearticles values(136.5 g); had high mean for tuber weight as compared to other clones. Nif-1 had the highest mean for plant yield as 920.2 g. Clone 122-1 was found to be higher than the other clones for plot yield insert ignore into journalissuearticles values(5.3 kg);. Clones of Atlantic-1; 2 and 3 insert ignore into journalissuearticles values(5.9 cm); had high tuber width and clones of Juwel-1; 2 and Hermes-2 insert ignore into journalissuearticles values(6.8 cm); had the highest means for tuber length.
