The results of the evaluation of linear type traits evaluation of Hungarian beef cattle populations were analysed by means of both traditional population genetic and multivariate biometric methods, i.e. by means of cluster analysis based on factor analysis. By using the multivariate methods it was possible to evaluate the different types of cattle with respect to type traits, reproductivity and productivity properties. It is proven by the results obtained that factor analysis is practicable in the judgement at the population level of the individual properties. A great number of type traits--27 or more--making an interrelating system can be analysed well by this method whilst the cluster analysis based on the factor analysis is suitable to classify the population on the basis of individual evaluation with simultaneous consideration of all type traits.
运用传统群体遗传学方法和多元生物统计学方法，即基于因子分析的聚类分析，对匈牙利肉牛群体线性类型性状评估结果进行了分析。通过使用多元方法，可以根据类型性状、繁殖力和生产性能对不同类型的牛进行评估。所得结果证明，因子分析在个体性状群体水平的判断中是可行的。该方法可以很好地分析大量（27个或更多）构成相互关联系统的类型性状，而基于因子分析的聚类分析适用于在同时考虑所有类型性状的个体评估基础上对群体进行分类。
