秩次分析法在国家绿豆品种区试数据分析中的应用

Application of rank analysis method to analyzing the data in regional trial of national mungbean varieties

运用秩次分析法对2006-2007年国家绿豆品种区域试验数据进行了分析,对各试验环境进行常规方差分析,通过对参试品种表现的秩次值、环境区分指数、秩次均方等统计数的计算,在多重比较的基础上,对各参试品种产量表现进行了客观评价。结果表明,参试的10个绿豆品种中XLD09、XLD01、XLD04具有最好的丰产性和较好的稳定性。分析结果也表明,秩次分析法对绿豆区域试验中参试品种产量性状的评价是一种实用、可行的数据处理方法。

The data from regional trial of national mungbean varieties was analyzed by using rank analysis method in 2006 -2007. Firstly, the result of the test was dealt with by variance analysis, and then three statistical parameters were estimated,namely the sequence numerals （H2Mi）, environment discrimination index （YM） and rank mean square（Si2）. Then based on the multiple comparisons, the tested varieties were evaluated objectively. The results of the comparison and analysis show that XLD09, XLD01 and XLD04 have the best yield performance and better stability. Meanwhile, the results indicate that rank analysis method is a practical and forthright data analysis method in evaluating mungbean yield in regional trials.
