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。

关键词: 一粒小麦, 核型

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.

Key words: T.monococcum, Karyotype
