水稻染色体组型的分析对于研究稻属的起源、系统演化,以及远缘杂种和染色体工程的细胞学鉴定等具有重要的意义。国内外学者对水稻染色体(2n=24)进行形态学研究时,多采用种子发芽后的根尖作为观察的适宜材料。由于水稻染色体较小,组型分析需要一定数量的种子,而一些珍贵的远缘杂种(如栽培稻与野生稻的杂交F_1)结实率极低,所得种子极少,就不可能利用该方法来分析组型。最近,我们试图采用水稻体
Analysis of rice genomes has important implications for the study of the origin, evolution, and cytological identification of distant hybrids and chromosomal engineering. Domestic and foreign scholars on the chromosome of rice (2n = 24) for morphological studies, the use of the root tip of the seed germination as the appropriate material for observation. Due to the small chromosomes in rice, a certain number of seeds are needed for the plant type analysis. However, it is not possible to use this method because the seed setting rate of some precious distant hybrids (such as hybrid F_1 between cultivated rice and wild rice) Analysis of the type. Recently, we tried to use rice bodies
