Abstract: In order to explore the effects of transplanting density of “Emma” virus-free potato plantlets in the Xigaza district in Tibet on the propagation of the original species, six different transplanting density groups (5 cm × 8 cm, 4 cm × 8 cm, 4 cm × 5 cm, 3 cm × 5 cm, 2 cm × 3 cm as experimental groups and 2 cm × 2 cm as control group respectively) were conducted to study their effects on the plant survive rate, plant character (plant height, number of blades, branching number and stem diameter, etc.), the total number of potatoes, and qualified number of potatoes more than 2 g. The results showed that when using the same age of seedlings and under the same condition of planting environment, transplanting density hardly had any effect on the survival rate of potato plants in greenhouses. While transplanting density influenced the plant character with certain regularity, which was along with the density increment, the plant height became smaller; the number of blades and branching decreased and the plant stem became slender. The optimal condition was in density of 5 cm × 8 cm, with the results of the most potatoes and maximum qualified numbers. Therefore, taken into comprehensive consideration of unit cost, total potatoes and qualified numbers, the density of 5 cm × 8 cm was a better choice for the potato plantlets transplanting.
