用西洋参作 DNA的供体 ,用栽培大豆品种作为受体 ,利用分子育种导入技术之一的“浸种法”进行外源 DNA导入 ,试图在继续保持大豆营养价值和具有的医疗保健作用的前提下 ,提高其已有的药用成分的含量和导入新的药用成分 ,培育出具更高药用价值或保健作用的栽培大豆新材料和新品系。目前导入后代在形态、品质和药物成分含量等性状方面产生了广泛的变异。本文报道了导入后代形态上的变异 Using American ginseng as a donor of DNA, using a cultivated soybean variety as a recipient, and using the “seeding method” of molecular breeding introduction technology for the introduction of foreign DNA, in an attempt to maintain the nutritional value and health care function of soybeans. , To increase the content of its existing medicinal ingredients and introduce new medicinal ingredients, to cultivate new materials and new strains of cultivated soybean with higher medicinal value or health effects. At present, the introduction of offspring has produced a wide range of traits in terms of morphology, quality, and drug composition content. This article reports on the morphological variation of imported progeny
