Comparison of Genetic Diversity between the Local Cultivated Aromatic and Non-aromatic Rice in Yunnan Province Using SSR Markers

[Objective] The genetic diversity of the local cultivated aromatic rice and non-aromatic in Yunnan were compared to further provide genetic resources for breeding practice.[Method]Genetic diversity of 10 aromatic rice and 45 non-aromatic cultivars were analyzed by 64 SSR primers covered on 12 rice chromosomes.[Result] Per locus 5.44 and 7.98 alleles in average were detected,ranging from 2 to 12 and from 2 to 17 in aromatic and non-aromatic rice,respectively.Average genetic multiplicity index(Hs) was 0.46 and 0.67,respectively.And average polymorphism information content(PIC) was 0.43 and 0.58 in aromatic and non-aromatic rice respectively.[Conclusion] The results indicated that genetic diversity was higher in non-aromatic rice than in aromatic rice.
