Abstract

Abstract: This study aims to explore the characteristics of the high and stable yield of new wheat variety Ping′an 0602 in different ecological regions.According to the results of Henan Province regional test in 2015—2017，the data were analyzed by yield，variable coefficient，high-stable yield coefficient，regression coefficient and coordinate method.The result showed that the yield of Ping′an 0602 was higher than that of the control variety by 7.04% and 4.83% in two years.Ping′an 0602 showed the characteristic of high yield.The regression coefficient at 1.056 5 and 1.019 9 was close to that of population 1.000.Ping′an 0602 showed the characteristic of stable yield.The value of high stability coefficient was lower than that of the control variety and the regression line was above that of population，both suggesting high and stable yield. Ping′an 0602 has a high extension value in the examination area.

Key words: Ping′an 0602, High and stable yielding, High-stable yield coefficient, Regression coefficient, Coordinate method
