A method of interbreeding in a stone orchid test tube has been patented by the United States

recently, Zeng Songjun, a researcher at the South China Botanical Garden of the Chinese Academy of Sciences, and others, obtained a patent license for the invention of the United States (patent number: US 9,936,654 B2).
The invention uses the method of interbreeding in the test tube can greatly shorten the ripening period of the fruit and make the hybrid offspring flower in the test tube in a short period of time and observe the flowering color, and cultivate new varieties, thus speeding up the breeding speed of the stone orchid, which is the first reported in the world. At the same time, due to the annual flowering of the stone in the test tube, it is able to carry out cross-breeding between species during the natural flowering period.
addition, the culture base used in all stages of the invention, its use of "flower treasure" as the main component of the culture base composition is unique, not only low cost, but also high flowering rate, fruit development. And the implementation of the invention only needs to have a simple plant tissue culture equipment can be carried out, so the whole breeding method is simple, low cost, for the cultivation of high-quality stone orchid varieties created conditions.
