评判棉花品种 ,传统的方法只是对棉花的产量进行方差分析 ,对其它的性状多是作定性描述 ,人为因素较大 ,不免会失之偏颇 ,鉴此 ,作者应用灰色关联度分析对南阳市农科所棉花引种试验材料进行综合定量分析评判 ,旨在为确定南阳盆地棉花生产用种提供科学依据。1 材料与方法1 .1
Judging the varieties of cotton, the traditional method only analyzes the variance of cotton yield, and mostly characterizes the other traits. The human factor is larger, which will inevitably lead to bias. Therefore, the author uses gray relational analysis Section of the introduction of cotton test material for quantitative analysis of quantitative evaluation, designed to determine the cotton production in Nanyang Basin to provide a scientific basis for species. 1 Materials and methods 1 .1
