乌红杂交天麻与乌天麻及红天麻经济性状分析

Analysis on Economic Character for Wuhong Hybrid Gastrodia Elata Bl.and Wu Gastrodia Elata Bl.as well as Hong Gastrodia Elata Bl.

试验表明:乌、红杂交天麻在有性原种栽培产量和天麻素含量上与亲本乌天麻、红天麻相比没有杂交优势;其杂交原种应用到商品麻栽培中,栽培总产量具有中亲优势;箭麻的产量、数量、个体均重和箭麻的加工性状的平均鲜品密度、含水率、折干率与两亲本相比都具有超亲优势;白麻和米麻的分化产量具负向优势。因此,推广应用杂交天麻是提高箭麻产量和品质的重要途径。

The test indicates Wu, Hong hybrid Gastrodia Elata B1. hasn＇t hybrid advantage in yield of sexual original species cultivation and Gastrodia Elata B1. element content compared to Wu Gastrodia Elata B1. and Hong Gastrodia Elata B1. ; total yield of the cultivation possesses medium parent advantage when applies its hybrid original species to commercial Gastrodia Elata B1. ; the yield, quantity, individual average weight of the commercial Gastrodia Elata B1. and average fresh commodity density, water content, dried ratio of the processing character of the commercial Gastrodia Elata B1. have super parent advantage compared to two parent; the differentiation yield of Bai and Mi Gastrodia Elata B1. have negative advantage. Therefore, extension and application of the hybrid Gastrodia Elata B1. are an importance of way to enhance the yield and quality of the commercial Gastrodia Elata B1.
