中国科学院遗传所经二十余年的努力,在国内首次育成一种新型青贮多秆多穗专用玉米——京多1号。它可以替代低产质次的普通单秆玉米品种,可以大幅度地提高青贮玉米产量,为发展养牛业提供丰富的优质青贮饲料,从而为我国人民提供更多的牛奶和牛肉。1985年八月中旬,农牧渔业部和中国科学院在河北承德联合召开了京多1号试种推广会议,决定在“三北”地区大面积推广。 京多1号玉米为单交种(风白29BGB)它杂种优势强,营养生长旺盛,青贮产量高,一般增产50％,高的增产一倍以上,最
After more than 20 years of hard work, the Institute of Genetics of the Chinese Academy of Sciences has bred a new type of silage multi-stalk and multi-spike corn-Jingdo-1 for the first time in China. It can replace ordinary single-stalk maize varieties with low yield and quality, can greatly increase the output of silage maize, provide abundant high-quality silage for the development of the cattle breeding industry, and provide more milk and beef for our people. In mid-August 1985, the Ministry of Agriculture, Animal Husbandry and Fishery and the Chinese Academy of Sciences jointly held the trial of the extension of the trial of planting seeds of “Jingdu 1” in Chengde, Hebei Province, and decided to promote it in a large area in the “Three Norths”. Jingdo 1 maize is a single cross variety (Fengbai 29BGB). It has strong heterosis, strong vegetative growth and high silage yield, generally increasing yield by 50% and high yield increasing by more than one time.
