The basic technology of potato virus-free seed potato: first germination and disinfection of the poisonous potato in the room; then, under the aseptic condition of the clean bench, the shoot apex meristem is cut and transplanted in the test tube for cultivation, after about 4 months The shoot apical meristem grew into a test tube seedling; the test tube seedlings were tested for viruses, and virus-free virus-free seedlings were identified from a large number of plants; then they were cut through rapid propagation and propagated in greenhouses and net sheds to obtain detoxification. The micro-tubers or original species can be obtained by re-breeding, and the original species can be re-bred into a first-class seed potato, a second-class seed potato and a third-order seed potato, generally collectively referred to as a virus-free seed potato.
Removed the major potato virus, restored the characteristics of the original species, to achieve the purpose of rejuvenation. Therefore, the virus-free potato has no virus, bacteria and fungal diseases in a certain period of time. Its vitality is particularly strong, and the yield increase is significant. Generally, it increases production by 30%-70%. As a result, the quality of the product is significantly improved, and rot, tip, crack, deformity, and sores that are easily caused by the planting of susceptible seed potatoes are greatly avoided. In addition, the transportation costs of seed potatoes are also significantly reduced. Due to the weight of virus-free mini-tubers only 2-5 grams, only 8-20 kilograms are used per acre.
