从水稻12条染色体上筛选出22对有效引物,对陕西省17个有色稻品种的遗传多样性进行分析,共检测到128个等位基因,平均每个标记检测到5.8个等位基因,每个SSR位点的遗传多态性信息含量在0.49～0.89之间,平均值为0.73。SSR聚类分析表明,陕西省17个有色稻品种的遗传相似系数在相似系数0.24处可以分为2类,其中绿稻单独聚为一类。用11个农艺性状聚类分析,在欧式距离为7.22处绿稻和其他品种聚为两类。
A total of 22 effective primers were screened from 12 chromosomes of rice. The genetic diversity of 17 non-colored rice cultivars in Shaanxi Province was analyzed. A total of 128 alleles were detected, with an average of 5.8 alleles per marker The genetic polymorphism information content of SSR loci ranged from 0.49 to 0.89 with an average of 0.73. SSR cluster analysis showed that the genetic similarity coefficients of 17 non-colored rice cultivars in Shaanxi Province could be divided into two types at the similarity coefficient of 0.24, of which the green rice clustered together as a single group. Cluster analysis of 11 agronomic traits showed that the green rice and other cultivars clustered into two types at the Euclidean distance of 7.22.
