甜菜维管束环的研究,归根结底,是要应用于甜菜育种实践,于是一个新的问题便向我们提了出来,在选择的压力下,甜菜的维管束环及环群中个体消长情况,即甜菜维管束环的选择效应如何?经过了选择实践,结果报导如下。材料与方法本试验用形态较一致,遗传性稳定的660—9—5、71—943—71和71—747—42三个品系。C_0代为传统选择法所获得的集团种子。C_1代的种子来自C_0代高环个体繁殖的集团种子。C_2代种子来自C_1代高环个体的集团种子。供试的品系,分别于81、83和85三年随机种在附近农家的地里,管理同一般甜菜。收获后将所得甜菜尽数收回,供室内检测维管束环用。
In the final analysis, the research on the vascular bundles of beet is to be applied to the practice of beet breeding. Therefore, a new problem is brought forward to us. Under the pressure of selection, the growth and development of the individual beetles in the vascular bundles and ring groups of beet What is the effect of the selection of the vascular bundle? After selection practice, the results are reported below. Materials and Methods This experiment with more consistent form, genetically stable 660-9-5, 71-943-71 and 71-747-42 three strains. C_0 replaces the seeds of the group obtained by the traditional selection method. The seeds of C_1 generation come from the seeds of C_0 generation of high-ring individuals. The seeds of C_2 were from the seeds of C_1 high-ring individuals. The tested lines were randomly planted in the nearby farmhouses for 81, 83 and 85 years to manage the same beets. After harvesting all the beet recovered, for indoor testing vascular ring use.
