Study on the Variation of Maize Inbred Line with Exogenous DNA

AN Ying-wei et al (Shenyang Agricultural University,Shenyang,Liaoning 110161)  
With a novel DNA transformation method,exogenous DNA was laid on the surfaces of ovariaes with cutting pathways of pollen tubes of each maize ear and total DNA extracted from inbred line-13A was introduced into Shen 109.The field investigation and indoors study indicated the character(growth period,plant height,ear heitht,plant shape and so on)were changed.The genetic variation freguency was relatively high.The variation frequency was 17.98%.It was verified by in situ hybridization.The offspring variation,variation frequency and characteristic of the technology were discussed.
