采用聚丙烯酰胺垂直板电泳技术对小麦族内的加拿大披碱草、野大麦及其杂种Ｆ１和蒙古冰草、航道冰草及其杂种Ｆ１、ＢＣ１的过氧化物酶（ＰＯＤ）同工酶做了比较研究。结果表明，每种植物的ＰＯＤ酶谱可明显分成Ａ、Ｂ两区，在Ｂ区有２条位点相同的酶带，为亲本的基带；所有供试材料呈现６～９条酶带，亲本与其杂种后代的酶谱表型有一定差异；ＰＯＤ同工酶具多态性，可作遗传标记用于杂种鉴定和回交后代目标性状植株的检测；加拿大披碱草×野大麦Ｆ１具双亲各自酶谱的强带，可能Ｆ１具两亲本的某些优良性状。
Polyacrylamide vertical plate electrophoresis was used to detect peroxidase (POD) isozymes of Canadian Elymus, Hordeum brevisubulatum F1 and Mongolian Tragopan A comparative study. The results showed that the POD zymogram of each plant was clearly divided into two regions A and B. There were two loci with the same locus in the B region and the parental loci. All the tested materials showed 6-9 bands, and the parents POD isozymes were polymorphic, which could be used as genetic markers for the identification of hybrids and backcrossing offspring of the target trait plants. Elymus × Wild Barley F1 had their own parents Strong bands of the zymogram may have some excellent traits of the F1 parent.
