We attempted develop DNA markers and their PCR primers to establish the methodology for classification of the varieties and breeding lines of crop species. In the first stage, we tested conditions of primers for producing confident and effect DNA fragments for the purpose. We found that 12-mer random primers having particular DNA sequences effectively produced DNA fragments than fully randomly designed primers. It was probable that controlling annealing temperature may result in more reliable banding pattern of electrophoresis. Such series of 12-mer primers are synthesized for the classification of cultivars and breeding lines of rice, orange and cucumber. The series of primers can be purchased through the researchers integrated in this project. By using these primers, indica and japonica of cultivated rice, and perennial and annual strains of wild rice were classified. In the case of oranges, traditional ecotypes defined by morphological and physiological traits were partly identified. In case of cucumber, male and female seedlings were distinguished. In the future, we attempt STS PCR that uses big-size primers designed based on the DNA sequences of the DNA fragments amplified by 12-mer random primers for more reliable classification.

我们尝试开发 DNA 标记及其 PCR 引物，以建立农作物品种和育种系的分类方法。在第一阶段，我们测试了用于产生可信且有效的 DNA 片段的引物条件。我们发现，具有特定 DNA 序列的 12 聚体随机引物比完全随机设计的引物更能有效地产生 DNA 片段。控制退火温度可能会产生更可靠的电泳条带图案。合成该系列12聚体引物用于水稻、柑橘和黄瓜的品种和育种系的分类。该系列引物可以通过参与该项目的研究人员购买。通过使用这些引物，对栽培稻的籼稻和粳稻以及野生稻的多年生和一年生品系进行了分类。就橙子而言，部分确定了由形态和生理特征定义的传统生态型。对于黄瓜，区分雄性和雌性幼苗。未来，我们尝试STS PCR，使用根据12聚体随机引物扩增的DNA片段的DNA序列设计的大尺寸引物，以进行更可靠的分类。
