油菜是我国重要的油料作物,在对其进行细胞遗传学研究和育种过程中,常常需要进行染色体检查。各物种的染色体组型,又是细胞遗传学和分类学等学科的基本资料。由于油菜染色体小而多等原因,应用根尖细胞往往难以制备出理想的染色体标本,使染色体计数和组 Rape is an important oilseed crop in our country. In its cytogenetics research and breeding process, it is often necessary to carry out chromosome examination. The karyotype of each species, but also the basic information of cytogenetics and taxonomy and other disciplines. Because rape chromosomes are small and many other reasons, the application of root tip cells is often difficult to prepare the ideal chromosome specimens, chromosome counts and groups
