Breeding of Good-quality High-yield Salt-tolerant and Drought-resistant Hybrid Cotton Variety Hengyou 12

Salt and drought tolerance, high yield and quality, disease and pest resistance of cotton varieties are new requirements for the current situation in cotton production. Hengyou 12 is a transgenic Bt cotton variety bred by hybridizing JD 28 （interspeciflc progeny of upland cotton, sea-island cotton, wild cotton species） as female parent with GK55 （transgenic Bt cotton variety） as male parent. The combining of parents was based on the complementary principle of parental traits. Hengyou 12 with strong heterosis was selected under disease stress, pest stress, salt stress and drought stress. This variety has many excellent characteristics, such as good resis- tance to diseases and pests, high yield, excellent quality, strong drought resistance and salt tolerance. ＇Hengyou12＇ was approved by Hebei Province in 2015, and is suitable for planting in middle and south areas of Hebei and similar ecological areas in the Yellow River basin.

优质高产耐盐抗旱杂交棉‘衡优12’的选育研究

耐盐抗旱、高产优质、抗病虫是当前棉花生产形势下对棉花品种提出的新要求。‘衡优12’是以具有陆地棉、海岛棉和野生棉遗传基础的高代材料‘JD28’作为母本,转Bt基因棉花品种‘GK55’为父本,依据亲本性状互补原理配置杂交组合,采用病害、虫害和盐旱逆境同步胁迫法,杂交选育而成的强优势转Bt基因抗虫杂交棉。该品种具有抗病虫性好、丰产稳产、品质优异、抗旱耐盐性强等诸多优异性状,适宜在冀中南及黄河流域同类生态春播棉区推广种植,2015年通过河北省农作物品种审定委员会审定(审定编号:冀审棉2015005号)。
