摘要
子代测定中以小区平均值进行方差分析及估算遗传力，单株遗传力的结果误差较大，用小区平均值作方差分析，外加计算小区内方差及调和平均株数，进而计算方差成分及遗传力，其结果与采用单株数据估算的结果相近，即使在试验数据严重不平衡的情况下，也不例外．该法可有效节省计算机资源及时间．本文以实例详细介绍了有关的计算方法．
For a progeny test, when analysis of variance is undertaken and heritabilities are calculated with plot means, the results of single tree heritability are not desirable. However, if carrying a plot means based analysis of variance with the within plot variances and the harmonic means of number of individuals per plot to be calculated separately, and then estimating the variance components and heritabilities, the results are similar to those which are estimated with individual observations even when the data set is of seriouse unbalance. A lot of computer resource and time can be saved under plot means based estimation. The data set from a field experiment was collected to show the detail method and process of this kind of analysis.
