【Abstract】 The yields and yield components of spring wheat of Ningchun No.4 were analysed in the variety comparison experiment from 1982 to 1993 and the district experiment in 1995.The results show that the Ningchun No.4 has mean stability in yield and develop ment homeostasis on different ecological conditions.The regressive coefficients can be used as parameters to measure the yield stability of wheat varieties.更多还原
