本研究以谷子(Panicum miliaceum L.)为材料，建立了基于PCR的蜡质基因分型标记。并对糯型日本地方品种的起源和扩散提出了新的假说。I-2-K染色表明，几乎所有日本地方品种都有蜡质胚乳。基于不同基因组上两个蜡质基因座的PCR和dCAPS分析，我们得出结论，亚洲大陆至少有两个可能的谱系具有独立的向日本扩散的途径。大多数日本谷子与朝鲜半岛的谷子具有相似的遗传型，但少数特别是来自日本北部的谷子在俄罗斯东北部的中国和俄罗斯的滨海省具有相同的遗传型。
We developed PCR-based markers for genotyping Waxy genes in common millet (Panicum miliaceum L.) and proposed a new hypothesis on the origin and dispersal of waxy type of Japanese landraces. I-2-K staining indicated that almost all the Japanese landraces had waxy endosperm. Based on the PCR and dCAPs analyses of two waxy loci on different genomes we concluded that there were at least two possible lineages in Asian continent that had independent dispersal pathways into Japan. Most Japanese common millet had the similar genotypes with those in Korean Peninsula but a few particularly from northern part of Japan had common genotypes in northeastern China and Primorskaya Province of Russia.
