用Eberhart-Russell模式和方法分析南充地区1980～87年区域试验中六个油菜(B.napus L.)品种的丰产性和稳产性。结果表明;参试品种的两种产量稳定性参数值都有较大差异,说明品种在本地区有不同的稳产性和适应性而产量与两种稳定性参数之间并没有相关。有的品种表现高产、稳产和适应性广,而稳产性好的品种一般至少有两个产量构成因素表现稳定。这种分析方法可以作为研究油菜品种的稳产性和适应性的有价值的手段有助于对参试品种作出较全面的评价,以便合理的推广利用。
The Eberhart-Russell model and method were used to analyze the yield and stability of six B. napus cultivars in the regional experiment in Nanchong from 1980 to 1987. The results showed that there were significant differences in the two yield stability parameters between the two cultivars, which indicated that the cultivars had different stability and adaptability in the region but the yield did not correlate with the two stability parameters. Some species showed high yield, stable yield and wide adaptability, while the varieties with good yield and stability generally had at least two stable yield components. This method can be used as a valuable tool to study the stability and adaptability of rapeseed varieties, which can help to make a more comprehensive evaluation of the tested varieties so as to promote the rational use.
