摘  要:
为了给燕麦品种的鉴定、推广以及改进区试资料的评价分析方法提供依据,利用秩次分析法对2003-2005年国家燕麦品种区域试验中参试的6个燕麦品种的产量表现进行了分析。在方差分析的基础上,通过对品种的秩次值、环境区分指数、秩次均方等统计数的计算,比较了品种的丰产性和稳定性。结果表明,秩次分析法能够客观、准确的评价参试品种的优劣,具有较高的应用价值。参试的燕麦品种中蒙燕833-1-1具有优良的丰产性和较好的稳定性,是一个值得推广的燕麦品种。

摘  要:
The rank analysis was employed to evaluate the yield potential of 6 oat varieties in national trail during 2003-2005.Firstly,the result of the test was dealt with variance analysis,and then three statistical parameters were estimated,namely the Sequence numerals(H2Mi),environment discrimination index(YM) and rank mean square(Si2).Based on these,the high-yield and stability of various varieties were compared and analyzed.The results showed that Mengyan 833-1-1 of tested varieties have the best yield performance and better stability.The rank analysis method is objective and reliable for evaluation of the crop varieties.
