高产、优质、抗枯黄萎病、适应性广是棉花育种的主要目标。利用具有海岛棉、陆地棉、中棉、野生瑟伯氏棉血统且遗传基础丰富的转基因抗虫棉品系抗8为母本,以兼抗枯萎病和黄萎病的冀棉18选系95-538为父本,采取在重病圃不防治棉铃虫胁迫选择、光合速率测定、旱薄盐碱地筛选等技术多措并举,选育出了具有海岛棉、陆地棉、中棉和野生瑟伯氏棉血统,抗枯黄萎病、抗旱、耐盐碱、光合速率高、纤维品质优良、增产潜力大的高产棉花杂交新品种冀杂1号。2006年通过了国家农作物品种审定委员会审定(审定编号:国审棉2006010号),是我国第1个通过国审的高抗枯萎病、抗黄萎病的“双抗”转Bt基因抗虫棉品种,对降低棉花生产中由枯黄萎病引起的损失、控制棉铃虫为害、推进河北棉花战略东移、加强旱薄盐碱地开发、促进棉花生产具有重大意义。
High yield, high quality, resistance to Verticillium wilt, wide adaptability is the main goal of cotton breeding. By using the transgenic insect-resistant cotton lines with sea-island cotton, upland cotton, mid-cotton and wild Cerberus cotton germplasm and genetically rich anti-8 cotton as the female parent and the Jiyuan 18-line 95- 538 as the male parent, taking the non-control bollworm stress selection in critically ill nurseries, measuring the photosynthetic rate and selecting the planktonic saline-alkali to take a multi-measure approach. Breeding cotton with island cotton, Upland Cotton, cotton and wild Cerberus breed , Resistant to Verticillium wilt, drought-resistant, salt-tolerant, high photosynthetic rate, good fiber quality, large yield potential of high-yielding hybrid cotton Jihe No. 1. In 2006, it passed the examination and approval of the National Crop Variety Approval Committee (Validation No.:2004006010), which is the first “Anti-Verticillium” anti-Verticillium wilt resistance transgenic Bt Cotton varieties, to reduce the loss of cotton caused by verticillium wilt, control cotton bollworm damage, advancing Hebei cotton strategy eastward, to strengthen the development of drought saline land, promote cotton production of great significance.
