摘要

利用40个SSR标记对90份越南地方彩色水稻材料的遗传多样性进行了分析。多态性等位基因的数量为每个位点3-12个,平均每个位点7.1个。水稻地方品种的相似系数在0.76~0.93之间波动;遗传相关水平为0.78。通过对90份水稻地方品种的亲缘关系分析,将其分为5组。结果表明,11个标记包括:M250、RM302、RM10926、RM208、RM227、RM17231、RM23251、RM5647、RM1376、RM339和RM228。这些标记可以有效地用于彩色水稻的遗传多样性,并为地方品种鉴定、地方种质保护提供特定的数据库和有用的材料,通过越南的水稻育种计划进一步提高彩色水稻的稻米质量。

Evaluation of Genetic Diversity of Local-Colored Rice Landraces Using SSR Markers
Analysis of genetic diversity of 90 Vietnamese local-colored rice accessions was evaluated by using 40 SSR markers. The numbers of polymorphic alleles ranged from 3 to 12 alleles per locus and average of 7.1 alleles per locus. The similarity coefficients of the rice landraces fluctuated from 0.76 to 0.93; at a genetic correlation level of 0.78. Ninety accessions of rice landraces were divided into five groups based on analysis of genetic relationships. The results have indicated that 11 markers included: M250, RM302, RM10926, RM208, RM227, RM17231, RM23251, RM5647, RM1376, RM339 and RM228 which gave the unique allele. These markers can be used effectively for genetic diversity of colored rice and provided a specific database and useful materials for landraces identification, local germplasm conservation for further colored rice improvement on rice quality via rice breeding programs in Vietnam.
