河北省棉花育种的研究进展及发展思路

The Achievements and Future Strategies of Cotton Breeding in Hebei Province

“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。

There were 29 cotton cultivars bred in the ninth five-year plan (4 examined and approved by National Crop Variety Examination Committee of China). Yield potential, fiber quality, resistance to disease and insect and earliness of the cultivars were greatly improved. Especially Za 66 F] was the first granted cultivar, which resists boll worm, with transformed gene in china. Since the competitions of high quality raw cotton and high technology cultivars with abroad will be more violent after joining into WTO, and diseases will be severe, and water resources will be scarce in main cotton area in Hebei province, the future breeding strategies must be adjusted to high quality fiber and drought resistance and multiple resistance to disease and insect and high yield potential. In this paper, the future breeding goals and key techniques for inheritance properties improving were also discussed
