模糊聚类分析是近十几年来发展很快的一种新的数学方法,对研究对象进行合理的分类,初见成效地进行了大量的探索性研究。国内在农作物育种领域内(1)、(2)得到应用,模糊聚类分析有着广阔的前途。农作物几乎所有的重要经济性状都表现数量遗传,都是由遗传和环境这两个因素所制约以及影响的,啤酒大麦的重要经济性状千粒重作为育种主要目标,也是由遗传和环境所决定的,各地所表现的不同品种均值间的变异性完全是来自遗传因素,而品种内的
Fuzzy clustering analysis is a new mathematic method developed rapidly in recent ten years. It makes a reasonable classification of the research objects and has carried out a large number of exploratory researches in the first place. In the domestic field of crop breeding (1), (2) are applied, fuzzy clustering analysis has a bright future. Almost all of the important economic traits of crops are quantitatively inherited, which are both controlled and influenced by the genetic and environmental factors. The important economic traits of beer barley. The 1000-grain weight is the main target of breeding and is also determined by the genetic and environmental factors. The variability manifested by the average of different breeds is entirely from genetic factors, and within the breed
