| Abstract: | Sweetpotato is a staple food and economic crop in our country.Its virosis harm is extremely serious. Virus free sweetpotatos from tip meristem culture could prevent and control virosis effectively. According to applied practice of breeding and production in Henan,the paper put forward four stage production procedures(the virus free test tube seedling,foundation seed,registered seed,certified seed)and the grading quality standard of virus free sweetpotato seed.Moreover,its system of breeding and suppling and the production size and quantity of four stage seed were introduced. |
