“九五”以来,河北省育成棉花品种29个,在产量潜力、纤维品质、抗病虫性、早熟性上都有较大提高,特别是转基因技术在棉花育种的应用成功,使抗棉铃虫育种有很大突破,率先育成了国内第1个通过审定的抗虫棉杂交种杂66F_1。随着国外优质原棉和高技术品种的竞争加剧以及河北省主产棉区病害日趋严重和水资源日益紧张,今后棉花育种目标应加强棉纤维品质育种,选育耐旱节水、兼抗多种病虫害、产量潜力大的品种和杂交种。提出了育种目标和棉花遗传改良关键技术。
Since the Ninth Five-Year Plan, 29 cotton varieties bred in Hebei Province have a great improvement in yield potential, fiber quality, pest resistance, and precocity. In particular, the successful application of transgenic technology in cotton breeding has made cotton bollworm Breeding a great breakthrough, took the lead to develop the first approved by the approved hybrid cotton hybrid 66F_1. With the intensified competition from high-quality raw cotton and high-tech varieties in foreign countries and the increasingly serious disease in the main producing areas in Hebei Province and the increasingly tense water resources, the future cotton breeding objectives should strengthen the quality breeding of cotton fiber, Pests and diseases, the yield potential varieties and hybrids. Proposed breeding target and cotton genetic improvement of key technologies.
