“8001”是我院玉米所用同源于8112×5003二环系的二个非姊妹组配的一个姊妹种自交系,是经我院玉米所多次反复筛选试验取得的一项新的科研成果,被专家誉为紧凑型玉米自交系育种史上的一次新的革命。育成三年来,经我院玉米所和吉林、辽宁、河北、山东、湖北、四川等地有关单位进行大面积试验:“8001”较“478”有三大突出优点; 一、制种产量高:用“8001”做母本制种可提高制种产量30—50％,在有些地区增产达100％以上,在山东夏制和在辽宁、吉林春制,亩制种产量高 “8001” is a sibling inbred line used by two non-sister groups of 8112 × 5003 ring system used by our hospital for maize. It is a new scientific research made through multiple repeated screening tests of maize in our hospital. Achievements, by experts as the compact maize inbred breeding history of a new revolution. In the past three years, there have been three large-scale tests conducted by our institute and Jilin, Liaoning, Hebei, Shandong, Hubei, Sichuan and other places: “8001” has three outstanding advantages over “478”; The “8001” maternal seed production can increase the seed production by 30-50% and the yield increase by 100% in some areas. In Shandong Xia system and in Liaoning spring and Jilin spring system, the yield per mu is higher
