Abstract:The test indicates Wu,Hong hybrid Gastrodia Elata Bl.hasn't hybrid advantage in yield of sexual original species cultivation and Gastrodia Elata Bl.element content compared to Wu Gastrodia Elata Bl.and Hong Gastrodia Elata Bl.;total yield of the cultivation possesses medium parent advantage when applies its hybrid original species to commercial Gastrodia Elata Bl.;the yield,quantity,individual average weight of the commercial Gastrodia Elata Bl.and average fresh commodity density,water content,dried ratio of the processing character of the commercial Gastrodia Elata Bl.have super parent advantage compared to two parent;the differentiation yield of Bai and Mi Gastrodia Elata Bl.have negative advantage.Therefore,extension and application of the hybrid Gastrodia Elata Bl.are an importance of way to enhance the yield and quality of the commercial Gastrodia Elata Bl.
