摘要
本文分析了春小麦品种宁春4号从1982年至1993年间品种比较试验和1995年区域试验的产量及其产量因素。结果表明,宁春4号的产量具平均稳定性,在不同生态环境条件下具自身发育调整性;回归系数 b 值可做为衡量小麦品种产量稳定性的参数。
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.
