Abstract: Salt and drought tolerance, high yield and quality, disease and insect resistance are the new requirement for cotton variety in current cotton production. The authors took‘JD 28’(high progeny of upland cotton, sea-island cotton and wild cotton species) as female parent and‘GK55’(transgenicBt cotton variety) as male parent. Hybrid combinations were disposed based on the complementary principle of parental traits. Strong heterosis hybrid‘Hengyou 12’was selected under synchronous stress with disease, pest, salt and drought stress. This variety had many excellent characteristics, such as good resistance to disease and insect, high and stable yield, excellent quality, strong drought resistance and salt tolerance, and so on.‘Hengyou12’ was approved by Hebei Province in 2015 (Approval number: Jishenmian 2015005) and was suitable for planting in Mid-south region of Hebei and similar ecological and spring sowing cotton areas in the Yellow River Basin.
