利用微卫星标记分析浙江省近年来主要水稻品种的遗传多样性
Microsatellite Marker Analysis on Genetic Diversity of Main Rice Varieties in Zhejiang Province, China
摘要
Abstract
Forty-four conventional rice varieties and 54 hybrid rice combinations in Zhejiang Province, China were assayed with a set of 12 microsatellite markers. A total of 68 alleles and 127 fingerprints from all tested materials were detected. The values of the frequency of polymorphism ranged from 0.567 to 0.905 with an average of 0.752. The conventional rice varieties and hybrid rice combinations both had obviously genetic difference among subspecies, but had less genetic difference within subspecies. The genetic diversity of indica type was higher than that of japonica type. The average genetic similarity coefficients within conventional indica, japonica and between indica and japonica rice varieties were 0.672, 0.711 and 0.103, respectively. The average genetic similarity coefficient within indica, japonica, and between indica and japonica hybrid rice combinations were 0.636, 0.669 and 0.343, respectively. Cluster analysis results showed that the conventional rice varieties and hybrid rice combinations were classified into 6 and 7 groups, respectively. Most of varieties or combinations with same type gathered into same group.关键词
