优良的甜菜多倍体品种,生活力、抗逆性、适应性、亩产量等方面均优于二倍体品种,因此甜菜多倍体育种越来越被人们所重视。在整个多倍体育种过程中,染色体倍数的测定相当重要。细胞学镜检是目前普遍使用的,确定植株倍数性和多倍体种子比例的最可靠的手段。镜检采用的制片力法,基本上大同小异,均需:取材、固定、解离、染色、压片、镜检等几道程序。就染色方法来说,从近年来国内发表的甜菜染色体研究,细胞分裂过程及多倍体镜检的有关文章来看,大部分甜菜研究和育种单位以醋酸——洋红或地衣红等方法染色观察,这两种方法是多年来沿用并验证的 Good beet varieties, viability, stress resistance, adaptability, yield and other aspects are superior to diploid varieties, so beet polyploidy more and more attention. In the entire polyploid breeding process, the determination of chromosome multiple is very important. Cytology is currently the most commonly used method to determine the multiplicity of plant polyploid seeds and the most reliable means. Microscopic examination using the production force, basically the same, are required: material, fixation, dissociation, staining, tableting, microscopy and other procedures. In terms of staining methods, from the beet chromosome research, cell division process and polyploidy microscopy published in China in recent years, most of the beet research and breeding units are stained with acetic acid-magenta or lichen red , Both of which have been used and validated over many years
