In this paper , genetic transformation systems by agrobacterhim rhizogems was established and optimized and high quality regenerating system was selected . the products of indigotin and indirubin in regenerating plantlets had been detected by hplc . the main studies and results were reported as follows : 1 establishment and selection of hairy root clones taken cotyledons of autotetraploid indigoblue woad as explants and hairy roots induced successfully from them by agrobaterium rhizogenes strains a4 and r1000 本文利用发根农杆菌rit - dna建立并优化了四倍体菘蓝的遗传转化体系，并对再生植株的主要代谢产物靛蓝、靛玉红进行了含量检测，筛选了优良无性系，也为实现外源抗虫、抗病等基因的导入奠定了基础。
