摘要
在1988年淮北地区大豆品种区域试验中,测定了9个大豆品种的丰产性和产量稳定性.结果显示,这些品种的适应性和产量稳定性的参数都相当不同.某一品种可显示高产、稳产和广泛的适应性,然而具有较好产量稳定性的栽培品种通常都含有稳产因子.本研究采用分析法评价大豆品种的稳产性和适应性,在一定范围内可较其他方法更为精确和全面.它可作为一项附加标准用以评价新品种.
The productivity and yield stability of nine soybean varieties was
tested in the 1988 s'soybean regional test in Huaibei area of Anhui.
The resuslts revealed that these varieties differed considerably from
parameter values of both yield stability and adaptability. One variety
showed high and stable yield and wide adaptation. and yet a cultivar
with better yield stability generally had stable yield components. The
analysis method used in this study might be more better than other
methods for estimating soybean's variety stability and adaptability ex-
actly and comprehensively over a range of environments. It could be
used as an additional criterion to evaluate new varieties.
