长期以来,农作物的选育种主要是根据作物的株型、穗型和粒型,以至产量、品质和抗性来选择的。无疑,这是行之有效的重要方法,而且也积累了丰富的经验。但如何把这些宏观的遗传现象,深入到微观的分子水平,以提高选择的效率,乃是选育种工作者共同关心的问题。近年提出,通过同工酶的分析,作为遗传育种的生化指标,就是从宏观到微观发展的一个值得重视的趋向。同工酶的涵义同工酶(Isozymes)一词最先由Markart及Moller于1959年提出,是指一些结构不同,而 For a long time, the breeding of crops was mainly based on crop type, panicle type and grain type, and even the yield, quality and resistance. Undoubtedly, this is an important and effective method, but also has accumulated rich experience. However, how to integrate these macroscopic genetic phenomena into the micro-molecular level to improve the efficiency of selection is a common concern for breeding workers. In recent years, through the analysis of isozymes, as a biochemical indicator of genetic breeding, is a macroscopic to micro development of a worthy of attention. Isozymes The term isozymes was first proposed by Markart and Moller in 1959 and refers to some structures that differ
