摘要
根据作物农艺性状整齐度研究中目前采用的整齐度指标方法所存在的缺陷，重新定义了整齐度的概念。并从变差分析入手，以0～100的整齐度数值域为目标，利用方差原理，论述和推导了整齐度的计算公式，提出了整齐度（rd）=[（x^-s）√x]×100的新指标方法。通过整齐度数值域上、下限的理论检验和与其它指标方法的比较，证明RD法是方法科学、计算简便、数值直观、标准最高的指标方法，可作为标准方法推广应用。
The conception of the regularity degree （RD） of crop agronomic traits was redefined based on the studies of the limitation of the index method adopted past. Starting with analysis of variation, targeting on 0～100 numerical range of the regularity degree and using the principles of variance. A formula of RD {rd = [（x^-s）√x]×100} was discussed and figured The RD index is scientific, easy for analysis, numerical intuitive and standard highest through theoretical tests of the upper or lower limit to numerical range of RD and comparison with other index methods. The RD index maybe used as a standard one.
