近年来,由于电泳技术的发展,使同工酶的研究愈来愈广泛。在遗传育种方面, 应用同工酶可以鉴别从外部形态上难以鉴别的遗传变异,因此,可以作为基因功能的良好标志。利用同工酶鉴定杂种以及对杂种亲本的选择和杂种优势的预测已有不少报道。此外应用同工酶鉴定远缘杂种也获得了明显的效果。如高粱稻的同工酶分析是用形态学及细胞学方法难以鉴定的远缘杂种、还可利用同工酶研究植物的进化及亲缘关系。但是对野燕麦同工酶的研究未见到 In recent years, due to the development of electrophoresis technology, the research of isozyme has become more and more widespread. In genetic breeding, isozymes can be used to identify genetic variants that are difficult to identify from the outside and thus can be used as a good marker of gene function. Isozymes have been used to identify hybrids and their selection of hybrid parents and the prediction of heterosis has been reported. In addition, isozyme identification of distant hybrids also obtained significant results. For example, isozyme analysis of sorghum and rice is a distant hybrid that can not be identified by morphological and cytological methods. Isoenzyme can also be used to study plant evolution and genetic relationship. However, the study of wild oats isozymes has not been seen
