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。 |

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. |
