鲜食大豆区试高产性、稳产性分析方法的评选

用适定性参数法、变异系数法、高稳系数法和回归系数法等4种分析方法,对参加2005年江苏省鲜食春大豆品种区试的各品种(系)的丰产性和稳定性进行了分析和评价.结果表明,这几种方法均可用于鲜食大豆区试结果分析,且分析结果类似,但各有优劣:适定性参数法、变异系数法和高稳系数法计算简便,但结果粗放;回归系数法计算繁琐,但结果精确.笔者认为在鲜食大豆区试汇总时应使用回归系数法.

The Evaluation and Selection of the High-yield and Stable-yield Analysis Method in Fresh Edible Soybean Regional Test

By using four methods of adaptable and stable parameter,variation coefficient,high steady coefficient,and recurrence coefficient,this paper analyzed and evaluated the high-yield and stable-yield character of the fresh edible soybean varieties in Jiangsu regional test in 2005.The results show that these methods can be used in fresh edible soybean regional test analysis,the results from each method are similar,however they have disadvantages and advantages respectively.The adaptable and stable parameter method,variation coefficient method,and the high steady coefficient method have simple calculating process,yet the results from them are extensive.The recurrence coefficient method has complicated calculating process,yet the result from it is accurate.With the responsible attitude to the varieties taken in the regional test,I think the recurrence coefficient method should be used in collecting and analyzing the data of the fresh edible soybean regional test.
