我们已经在“甜菜三体研究动态”一文中,评述了糖甜菜三体的获得、特性及其在遗传研究中的意义。从那时以来,我国甜菜工作者对糖甜菜三体的兴趣激增,积极开展了这方面的工作,并且巳取得了可喜的初步结果。为了更深入地研究糖甜菜三体系列,我们对不同作者的从形态特征鉴别甜菜三体的研究,进行了初步分析和讨论。一、糖甜菜三体形态变化的类别当个别同源染色体附加于该物种正常染色体组之后,这个附加染色体对个体将产生明显
We have already commented on the acquisition and characteristics of sugar beet three-body and its significance in genetic research in the article “The Dynamic Research of Three-body Sugar Beet”. Since then, there has been a surge of interest in sugar beet tasting among sugar beet workers in our country. The work has been actively carried out in this area and gratifying preliminary results have been achieved. In order to further study the sugar beet trisomy series, we conducted a preliminary analysis and discussion on the identification of sugar beet trisomy by morphological characteristics of different authors. First, sugar beet trisomy morphological changes in category When individual homologous chromosomes attached to the species of normal chromosome group, this additional chromosome will produce significant individual
