染色体是遗传物质的载体。掌握细胞分裂的规律,进行染色体的观察,是细胞学研究的基础,是鉴别生物遗传与变异的重要依据。 菜豆的染色体较小,观察不易,这可能是国内外对菜豆细胞减数分裂报道很少的原因。菜豆染色体基数n=11,形态似短棒状。为了提供遗传育种工作者对菜豆染色体研 Chromosomes are carriers of genetic material. Grasp the law of cell division, the observation of chromosomes is the basis of cytology, is an important basis for identification of biological genetic and variation. The chromosomes of the kidney bean are small and not easy to be observed. This may be the reason why the meiosis of the kidney bean cell is rarely reported at home and abroad. Bean chromosome base number n = 11, shaped like a short rod. In order to provide genetic breeding workers on bean chromosome research
