玉米杂种优势的电泳分析

An Analysis of Electrophoresis to Heterosis of Maize

通过垂直板聚丙烯酰胺凝胶电泳方法，分析了几个玉米杂交品种及其亲本的过氧化物酶、酯酶同工酶、可溶性蛋白和脂蛋白，经对其谱带特征的综合分析，可更准确地鉴定和预测玉米杂交品种杂交优势的强弱，为玉米育种工作提供了选配亲本的理论依据。

in this paper the author measured the ways of polyacrylamide gel electrophoresis (PAGE), introduced peroxidase (POD) isozyme, esterase isozyme, soluble protein and lipoprotein in some hybridization breeds and parents of maize. By means of its specific zymograms of synthetical analysis,the reserachers can further appraise and calculate accurately heterosis's strength and weakness of hybridization breeds of maize. These would provide aparental selection theoretical basis for breeding work of maize.
