黑龙江省小麦地方品种──大青芒亲缘关系浅析

Analysis of Blood Relationship Among Local Breeds -Dagingmangsin Heilongjang Province

本研究通过过氧化物同工酶来确定品种血缘关系。结果证明过氧化物酶特征明显，相对稳定，配合其它生态、生理指标测定，可以作为小麦种质资源分析重要的手段之一。对黑龙江省小麦地方品种１９个大青芒来源不同，植物学形态十分相似，进行了酶谱分析；白奎大青芒、富锦大青芒、呼兰大青芒的过氧化物酶酶谱完全一致，它们的植物学形态相同，蛋白质含量相差无几，证明它们同出一源。

This researeh was focused on determing blood relationship among different breeds throughanalysing peroxidase isoenzyme.Result of the research showed that characters of perokidape enzymewere very obvious and relatively stable;therefore, with,other ecological and physiological measuring indexes.This method could be one of important methods for analysis of wheat germplasm resources.19local breeds in Heilongjiang province,from different Dagingmang sources but with similar plant development,were analyses on zymogram.The peroxidaps zymograms of Baikui Daging mang,Fujin Dagingmang and Hulan Daqingmans were absolutely the same.Their plant developments were the same,andtheir protein,contents were alment the same.This indicates that they come from the same source.
