| Abstract: | By employing a novel DNA transformation method for maize that exogenous DNA is laid on the surfaces of ovaries with cut pathways of pollen tubes on each ear, a mixed exogenous genomic DNA sample, which contains the genomic DNA samples extracted from maize, tripsacum and teosinte respectively that have some traits such as short stem, high cutin content, strong resistances to some diseases and lodging resistance, was introduced into a maize inbred line. A new line 25114, which has these traits and high combining ability of yield, as female parent, was used to cross a promising hybrid. |
