摘 要:采用秩次分析法对河南省2004年夏大豆区试中11个供试品种(系)产量表现进行了评价。介绍了评价品种表现的平均数分级值(H1)、秩次值(H2)及环境区分指数(YM)等3个统计数,以及品种间秩次平均数显著性差异的多重比较方法。结果表明:在11个有效环境点中,濮129和驻豆5号产量表现的平均秩次值(H2i)较小,与其他品种(系)有显著差异,为高产品种。The yields of summer soybean varieties from eleven of regional trials in 2004 were evaluated using rank analysis method. There were three statistical parameters in the method. They were respectively grade numerals of average (H1)and rank numerals (H2)that appraised the variety traits, circumstance differentiating index (YM)that appraised the circumstances as well as. And the multiple comparison method carried on test of significance through the rank average among various varieties. The results indicated that eleven tested environments was effective. Average rank numerals (H2)of Pu129 and Zhudou 5 varieties yields were less in tested environments. There was significant difference among the two varieties with other varieties.They were two new varieties of high yield.
