| 摘 要： | 利用火焰干燥涂片方法制备染色体玻片标本。 比较了栽培一粒小麦和野生一粒小麦
10个不同材料的核型。细胞学观察表明，它们的核型很相似，可能同属小麦的A染色体组。它
们都具有7对染色体(2n＝14)， 即5对中部着丝点染色体和两对亚中部着丝点染色体。所有材料的第5对染色体都带有随体。

| Abstract: | The comparisom of karyotypes between 10 different materials of T. monococcum and T. boeoticum was carried out using flame-drying slides prepared by smear method. Cytological observation shows that their karyotypes appear very similar and may belong to the genome A of wheat. They both are found to possess 7 pairs of chromosomes (2n=14), i.e. 5 pairs of metacentric and 2 pairs of submetacentric chromosomes. All the No. 5 chromosomes have a satellite. |
