摘　　要：GK1 9是我国自育的转Bt基因棉花新品系。该品系对棉铃虫、红铃虫抗性突出 ,可减少蕾铃受害率 90 %以上 ,节省治虫费用 90 % ;抗病性及纤维品质均好 ,产量性状构成水平高。GK1GK19 is a new cotton variety of transgenic insect resistance,which was selected by Chinese breeders.It showed the significant resistance to Holithis armigera H. and Pectinophora gossypiella S. According to the result of field trials and planting demonstration in 1999,it reduced over 90% of the damage on cotton bud and boll by insects.GK19 could cut the cost of insect control down by 90% as well.This variety showed good specific properties on disease resistance,quality of cotton fiber and high yield.GK19 could be recommended to plant in Hubei Province.
