| Abstract: | Using a series of recipients, such as wild sesame of Congo and Guatemala, sorghum, exogenous DNA was introduced into Yuzhi No.4 by pollen tube path way in suitable time, and variations had been abtained. After selected and identified generation-by-generation a series of germplasm resource of sesame were developed. The pollen tubes path way observation under microscope showed that the best introducing period was from 4 to 6 hours after pollination. |
