一个作物的品种区域试验,除要分析产量和一些单一性状以外,因生物存在着多基因效应以及基因的多效应现象,往往还需要分析一些由单一性状综合而成的复合性状。例如丰产性,早熟性、抗逆性等等。但到目前止,还没有一种理想的办法。原因是用以推断品种间复合性状差异的数据,由于是不同性状组成,在量纲与属性方面均不相同,故不能直接用数理统计进行分析。因此,目前的许多试验报告
In addition to the analysis of yield and some single traits, regional testing of a crop often requires the analysis of complex traits consisting of a single trait, because of the polygenic effect of organisms and the multi-effect of the gene. Such as high yield, precocity, resistance and so on. But so far, there is no ideal solution. The reason is that the data used to infer the differences in the composite traits among cultivars can not be directly analyzed by mathematical statistics because they are composed of different traits and are different in dimension and attribute. Therefore, many current test reports
