摘 要:依据国家棉花育种攻关指标,以大铃、高产和抗病虫为主攻方向,通过亲本的广泛筛选,利用丰产性、抗病性突出的远缘杂交后代做母本,与结铃性强、高抗棉铃虫的新品系进行杂交,经过多年南繁北育连续选择、早代纤维品质检测、病圃抗病性鉴定以及多环境适应性鉴定等,选育出转B t基因棉花新品种"冀丰106"。该品种2005年通过了河北省审定,2006年通过了天津市认定,2007年通过了山西省认定,并被列入河北省棉花良种补贴项目品种,目前在棉花生产上发挥着重要作用。Depending on the mainly targets of cotton breeding of country, we regarded the big boll, high-yield and diease & insect resistance as mainly studying way. Trough selecting a lots of parents, we used the distant hybridization progeny with excellent high yielding capacity and diease resistance as female, with many bolls and high resistance to cottton boll worm line as male, by south and north breeding of many years, testing fiber properities in early, identfying diease resistance in diease soil, idenffy adapation under muti-environment, we breeded new cotton variety Jifeng 106 with Bt transgenic, it was authorized by Hebei Province Plant Committee in 2005, It was also authorized by Tianjing City and Shanxi Province Plant Committee in 2006 and 2007. Jifeng 106 was also lined excellent cotton supplied variety, It played an important role in cotton production.
