Abstract
The invention relates to a method for producing virus-free potato breeder's stock. The method comprises the step of: planting virus-free potato test tube seedlings in a medium composed of nutrient soil at the lower layer, river sand at the middle layer and vermiculite at the upper layer so as to carry out mixed three-dimensional layered planting. The method has the characteristics that: the production cost of the potato breeder's stock is greatly reduced, and the unit area producing number of seeds and the weight of single grain are greatly improved at the same time, so that the production bottle-neck restriction of the potato breeder's stock is overcome, and the breeding and popularization and application of the virus-free potato are accelerated, thus elevation of the production level of potato and rapid development of the potato industry are promoted.
