| 摘 要： | 对山西省几个优质小麦品种进行了系谱追溯，分析了其优质性状及其它主要农艺性状的遗传来源。结果认为，这些优质品种多有国外血统，遗传基础丰富；但优质品种间亲缘关系近，优质源利用单调。在优质育种中应重视不同优质源的利用，尤其异质优质源的结合，在小麦品质性状改良上，既要重视蛋白质含量，也要重视蛋白质质量即优质亚基组成。

| Abstract: | Analysis on the pedigree of several high quality wheat varieties in Shanxi province, and their genetic source of super quality and other main agronomic characters were analysed in this paper. The results showed that all of these high quality wheat varieteies have had the blood of foreign varieties, their genetic bases were plentiful. But, many of them were the relation of affinity. As far as these high quality wheat varieties, their high quality source were very less. The utilization of different high quality source must be stressed in super quality breeding. Protein content or protein quality also must be stressed in improvement of quality characters. |
