为鉴定按表型选择所选出的优树其遗传型是否优良,我们进行了此项研究。无性系测定,不经过有性过程,细胞的有丝分裂保证了染色体和DNA分子准确的自我复制,每个无性系具有与母本完全相同的基因型,所以此测定可以准确地鉴别遗传和环境对表型的作用,及早淘汰不良单株,不断提高刺槐的遗传品质。经三年的连续测定,筛选出可推广的优良无性系9个,报告如下。
We conducted this study to identify elite genotypes that are selected by phenotypic selection. Clonal determination, without sexual processes, cell mitosis to ensure accurate self-duplication of chromosomes and DNA molecules, each clone has exactly the same genotype as the female parent, so this assay can accurately identify the genetic and environmental pairs of the table Type of role, early out of bad plants, and continuously improve the genetic quality of black locust. After three years of continuous determination, can be screened to promote excellent clones 9, the report is as follows.
