Dai M.H., Liu L.Y., Li Y., Liu C., and Wu Z.L., 2021, Breeding of drought-resistance and salt-tolerance, suitable for machine picking new cotton variety Hengmian HD008, Molecular Plant Breeding, 12(36): 1-6 (doi: 10.5376/mpb.2021.12.0036)

Under the background of improving agricultural quality and efficiency, the new requirements for cotton varieties were put forward. Dryland Farming Institute, Hebei Academy of Agricultural and Forestry Sciences took ‘Hengmian 4’ (resource material of middle-early maturity and disease-resistant upland cotton) as female parent and RILNnXu0022HF (resource material of high quality upland cotton) as male parent to carry out hybrid combinations. After years of continuous directional selection, Hengmian HD008 was selected under disease stress, pest stress, salt stress and drought stress. Hengmian HD008 has the outstanding performance of drought and salt tolerance, high quality and yield, suitable for machine picking，which was approved by Hebei Province in August 2019 (Approved number: Jishenmian 20199003) and was suitable for planting in Hebei Province and similar ecological and spring sowing cotton areas in the Yellow River Basin.
