| 摘 要： | 为深入了解甘蔗重要亲本粤农73-204(YN73-204)及其衍生品种之间的遗传关系,利用SSR标记研究了甘蔗亲本粤农73-204及其衍生系、相关品种共计20份甘蔗材料的遗传多样性.结果显示,52对SSR引物检测到512个变异位点,每对引物平均为9.8个,变幅为5～20个.20份甘蔗材料遗传多样性GS变幅为0.6518～0.9086,整体遗传差异相对较小.54对引物多态性信息含量(PIC)变幅为0～0.50,平均为0.29.UPGMA聚类分析将20份甘蔗材料分成4大类,聚类结果能较好地反映品种之间的遗传关系.

| Abstract: | In order to evaluate the genetic relationship among sugarcane parent YN73-204 and its deritives, 52
SSR makers were used based on 20 materials of sugarcane parent YN73-204 and its deritives. The results showed
that a total of 512 alleles were detected with range of 5-20 alleles and an average of 9.8 of each SSR primer. Genetic
similarities (GS) were ranged from 0.6518 to 0.9086. Polymorphism information content (PIC) varied from 0 to 0.50,
with average of 0.29. By Clustering analysis with UPGMA method, 20 materials were divided into 4 categories. The
results could be useful to future breeding programs for increasing genetic diversity of sugarcane varieties. |
