摘 要:早熟、抗病虫、增产潜力大、适应性广、管理简便、适于机械化栽培是现代农业发展对棉花品种的基本要求。利用现代转基因技术和传统远缘杂交方法,培育具有海岛棉、陆地棉、野生瑟伯氏棉血统,目标性状突出且综合性状优良的杂交亲本;按照父母本性状互补的选配原则,配制杂交组合;通过重病圃胁迫、干旱胁迫、盐害胁迫、高虫口密度胁迫等高压选择、多点鉴定综合筛选和国家检验监督机构检测等手段,选育出了遗传基础丰富且携带外源抗虫Bt基因的抗虫杂交棉品种冀杂999。该品种突出表现早熟,生长稳健易管理,抗病虫,抗逆性好,适应性广,高产稳产,吐絮肥畅,含絮适中,纤维品质优良,适于机械化采收。2009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2009008),准予在黄河流域春播棉区推广。该品种的推广,对降低由枯黄萎病引起的损失、控制棉铃虫等鳞翅目害虫为害、推进河北棉花战略东移、提升棉花生产机械化水平和提高植棉效益具有重要意义。New cotton varieties with early maturity, resistance to diseases and pests, potential yield increase, wide adaptability, easy to manage, suitable for mechanized farming can meet the demands of the rapid developing modern agriculture.The foundation parents from distant hybridization between upland cotton, sea island cotton and wild relatives were developed by modern transgenic technology and traditional distant hybridization method.Based on parent allocation principle of trait complementary and accumulation, local variety were applied as center parent in our selection and extension to get effective combination of goal traits.The cross combination were selected under different environmental pressures, and continuous high stress pressures, such as drought and salt, diseases, pests, then new variety Jiza 999 with genetically abundant was bred.As a result of early maturing, high yield, good quality, disease resistance, multi-stress resistance and wide adaptability, easy to management for picking mechanization, it was approved by the National Crops Variety Approval Committee in 2009 and released in Yellow River Basin cotton-growing areas.The spread and application of this variety can reduce the losses for wilt diseases and lepidopterous pests, advance the cotton strategic adjustment of Hebei Province, and improve the mechanization level of cotton production and the efficiency of the cotton.
