摘要: [Objective] The genetic diversity of the local cultivated aromatic rice and non-aromatic rice in Yunnan Province were compared to provide further genetic resources for breeding practice.[Method] Genetic diversity of 10 aromatic rice and 45 non-aromatic rice 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. The 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.
