Method for stabilizing black and red hybrid gastrodia elata seed source

The invention provides a method for stabilizing a black and red hybrid gastrodia elata seed source. The method comprises the following steps: wild collection; screening after collection; establishing a gastrodia elata and gastrodia elata parent base; screening parent seedlings; and cultivating new seedlings of the black and red hybrid gastrodia elata. According to the method for stabilizing the gastrodia elata f.glauca and gastrodia elata hybrid seed sources, the unique altitude geographic advantage of the Shennong forest region and the southern Zhangzhou county and the resource advantage of wild gastrodia elata are used as collection places of parent breeding species, and gastrodia elata f.glauca and gastrodia elata f.glauca of the two places have high adaptability after iteration evolution in the geographic environment; high-quality seedlings are selected as culture species of parents, and the seedlings can be traced and have high adaptive capacity, so that the established black and red hybrid gastrodia ela
