【摘要】 根据生产实践需要针对作物适应性试验中多环境点未设重复的品种评价提出一种新的秩次分析法。用于未设重复的多点试验统计分析资料应符合三个基本假定:(1)各试验环境点具有同等重要性,试验环境点间无权重之分;(2)同一试验环境点符合唯一差异(供试品种)原则;(3)同一试验环境点内,试验环境仅具有随机误差,且服从正态分布。将供试品种间观察值标准差(Sv)与其秩次值最小理论标准差(σv)的商定义为无重复的品种间显著性差异比较尺度(LSD)。通过小豆作物的区域试验资料实例对该方法进行了验证,结果可靠,方法实用、简捷。更多还原

【Abstract】 Based on practical demands, the rank analysis method of evaluating crop varieties yield in regional trials without replication was proposed. The statistical data of yield in regional trials without replication should match the following supposition: (1) every environment point in regional trials has the equal importance and no difference in weight. (2) The environment points of same trials match unique difference (provided variety) principle; (3) In the environment point of same trial, the environment of trials has only random error and obeys the normal distribution. The quotient of standard deviation (Sv)and theoretical standard(σv)deviation of samples are defined as level of significant difference (LSD) among varieties. This method has proved to be reliable, practical and forthright by the concrete example of regional trials of adzuki bean.更多还原
