应用秩次分析法对大豆区试中品种产量表现的评价

Evaluation of Rank Analysis Method on Yield of Soybean Varieties in Regional Trials

本文采用秩次分析法对北京市１９９３—１９９５年夏大豆区试中１８个供试品种（系）产量表现进行了评价．研究结果表明：在１５个试验环境点次中，只有１３个点次为有效试验环境点；在这１３个有效环境点中，５０００２和５０３０２产量表现的平均秩次值（Ｈ２）较小，与其它品种（系）有显著差异，为高产新品系．

The yields of soybean varieties from eighteen of regional trials in the summer of 1993~1995 were evaluated using a rank analysis method. The results indicated that ten of twelev tested environments was effective. Average rank numerals (H2) of 50002 and 50302 varieties yields were less in theten tested environments. There was significant difference among the two varieties with other varieties. They were two new varieties of high yield.
