【摘要】 本文采用秩次分析法对河南省2006年夏玉米区试中11个供试品种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8个有效环境点中,洛单248、GD13和创玉1号产量表现的平均秩次值(H2i)较小,与其他品种有显著差异,为高产品种。更多还原

【Abstract】 The yields of summer maize varieties from eleven of regional trials in 2006 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 vari- eties. The results indicated that eight tested environments was effective. Average rank numerals (H2)of Luodan 248, GD13 and Chuangyu 1 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.更多还原
