Abstract: To assess the environmental adaptability, stress resistance and high yield of the new wheat variety ‘Pingmai 189’, the yield, effective spike number, grain number per spike, 1000-grain weight, the maximum tiller number, spike forming rate, plant height, black embryo rate of‘Pingmai 189’in different areas of Henan were investigated and analyzed with traditional seed cupping method. Results showed that‘Pingmai189’had better adaptability and stability in many agronomic characters, such as, effective spike number, grain number per spike, 1000-grain weight, the maximum tiller number, spike forming rate, plant height, black embryo rate and other related characters. In addition, the drought resistance index of‘Pingmai189’was 0.921 and its drought resistance level reached the third level in 2015, and that of 2016 was 0.800, which belongs to the fourth level, the comprehensive performance of drought resistance was better. The disease resistance of ‘Pingmai189’to stripe rust and sheath blight was medium in 2015 and 2016. The comprehensive analysis show that‘Pingmai 189’has better wide adaptability and stability in main agronomic characters, and is suitable for planting in Henan and its bordering areas.
