| Abstract: | Under stress conditions, through the breeding methodology of gene transfer and backcross election, we have improved Huangzao 4 with another super inbred-line 525 on the characters of the resistance-spot and early ripeness and selected a improved line with resistance-spot and early ripeness. And then,with the improved line,we have selected a newsummer seeding corn hybrid-"Jinnu 5"which has been proved superior to Yedan 4 an widely adaptable to Beijing , Tianjin and the areas around which with early ripeness resistance to diseases and super synthetic characters. It can provide high and stable yield for summer corn produce in the areas above. |
