作物区试中品种产量性状评价的秩次分析法

The Analysis Based on Ranks of Crop Varieties in Regional Trials

根据生物统计学的基本原理和方法提出作物区试中品种产量等性状评价的秩次分析法,介绍了评价品种表现的平均数分级值H_1、秩次值H_2及环境区分指数Y_M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.

The rank analysis method based on fundamental tenets of biometrics were proposed for evaluating traits of crop varieties in regional trials. 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.
