| description | The invention discloses a method for breeding stock seeds of small intact virus-free potatoes, and belongs to the field of crops. The method includes steps of selecting stock seed breeding bases; carrying out preparation work before seeds are sowed; managing fertilizers and water in the bases. The method includes particular procedures of taking out stored stock seed potatoes before the seeds are sowed, rejecting diseased potatoes and rotten potatoes, then placing the stock seed potatoes in indoor environments with scattered light at the temperatures of 18-22 DEG C, allowing the stock seed potatoes to naturally sprout by means of dormancy, promoting buds to turn green and selecting the stock seeds which pass the dormancy and have short and robust buds to be used as seed potatoes; planting the stock seeds of potatoes at certain seed sowing density. The seed sowing density includes that the plant spacing is 10-12 cm for the potatoes with the weights of 3-20 g, and the planting spacing is 13-15 cm for the potatoe |
