[Genetic diversity of D-genome revealed by SSR markers in synthesized hexaploid wheat introduced from CIMMYT].
Yi Chuan Xue Bao. 2002 Jun; 29(6):542-8.YC

Abstract

Simple sequence repeat (SSR) molecular marker was used to measure the genetic diversity of D-genome in 26 synthesized hexaploid wheat (AABBDD) introduced from CIMMYT. Twenty-three D-genome specific SSR primers were selected for PCR amplification, among which 22 primers can detect polymorphism. A total of 92 alleles were identified at 23 loci using the above SSR primers, with an average of 4 alleles per locus. The 92 alleles were used to calculate Nei's similarity index (GS) and the genetic distance (GD). It was also found that the mean genetic distance between 26 synthesized hexaploid wheat was 0.4955, which was obviously high. From the above results, it can be indicated that the genetic variation of D-genome in synthesized hexaploid wheat was abundant and could be used to improve the genetic diversity in wheat breeding. Interestingly, synthesized hexaploid wheat 17 and 18 shared the same D-genome donor, but three of 23 detected SSR loci were polymorphic between the two materials. Therefore, during the period of allopolyploidization, there was genetic differentiation in repeat region of donor genome.
