Co tton Science 2007, 19( 5) : 362~ 368 生物技术在棉花育种中的应用 , ( 中国农业科学院棉花研究所, 农业部棉花遗传改良重点开放实验室, 河南 安阳455000) : 棉花生物技 在细胞工程及基因工程等方面已取得了较大进展细胞工程中, 通过胚珠 培养体细胞培养等技 获得了一些新种质材料; 基因工程方面, 随着农杆菌介导法基因枪轰 击法及花粉管通道法等技 的突破, 在棉花抗病虫害和及抗除草剂等方面的育种获得成功, 相 应的新品种已开始了商业化生产我国棉花生物技 在抗棉铃虫等方面达到世界领先水平, 其他方面尚有差距棉花生物技 上应加强基因工程的实效性, 同时加大细胞工程的研究力 度本文综述了棉花生物技 的研究历程, 总结了其在我国棉花育种中的应用进展和取得的 成就, 分析了我国棉花生物技 存在的主要问题, 提出了相应的发展对策与建议 : 棉花; 生物技 ; 育种; 发展对策 : Q035. 3 : A : 2007) Appli cations of Biotechnology on the Cotton Breeding L Fug uang, L U Chuanliang (CottonResearch Institute, ChineseA cademy of Agricultural Sciences,K ey Laboratory of Cotton Ge netic Imp rovement, M inistry of A griculture, Anyang, enan 455000, China) Abstract: Co tto n bio technolog y is achiv ed m ainly in cell eng ineering and genet ic eng ineer ing. M any new g er mplasms are obtained via cell eng ineer ing, especilly immatur e embry o culture and tissue cul ture. T he same t ime, cotto n g enet ic eng ineering is succeeded due t o prog resses of Agr obat erium tum ef iciens mediat ed met hod, part icle bombardm ent met ho d and pollentube pat hw ay. M any transgenic cott on lines, w hich are acquired different f orein g enes including pest resistant g ene, her bicide resist ant gene, are applied in cotto n br eeding, subsequently, new varieties are comm ercialized in market . n China, it is advanced on transg enic bollw orm resist ant cotto n in the w orld, while the ot hers have man y t hing s to do. Cott on bio technolg y should be enhanced on t he efficacy of genet ic engeering and re search of cell engineering . Based o n analysis of r esearch hist ory of cott on biot echnolo gy, and nat ional pro gress and achiev em ent s transg enic cott on breeding in China, this ar ticle indicates main pro blems and relat ed solut io ns in cotto n biot echno logy,
