几种稳定性分析法在大豆品种区试中的应用与评析

Application and Assessment of Several Methods of Stable-Production Character in Soybean's Regional Experiment

利用2004年度国家北方春大豆区域试验(中熟组)资料,通过联合方差分析、F测验、新复极差测验、变异系数、回归参数法和HSC法,分别对吉农17和其它6个品种的丰产性和稳产性进行分析和比较。结果表明,采用HSC法评价各参试品种的优劣准确、可靠、简便易行;吉农17、P9231和公交03-1212等品种增产显著,地点适应性较佳,显示其具有较高的丰产性和稳产性。

Using data of national northern soybean＇s regional experiment （mid-mature group） in 2004 as original material, the productivity and stability of ＂Jinong 17＂ and other 6 soybean were analyzed and compared by united variance analysis, F test, variable coefficient, regressed parameter and high stability coefficient. The results showed that it is accurate, assured and convenient to assess soybean varieties by using high stability coefficient. ＂Jinong 17＂, ＂P9231＂ and ＂Gongjiao 03-1212＂ are notable in increasing production and adaptability, and they are high and stable production soybean varieties.
