Subject:
Triticum aestivum; alleles; cultivars; dominant genes; epistasis; genetic markers; genotype; growth habit; hexaploidy; loci; spring; vernalization; winter; winter wheat
Abstract:
... At a molecular level, the length of the vernalization period of common wheat (Triticum aestivum L.) is determined mainly by three loci: VRN-1, VRN-2 and VRN-3. In hexaploid wheat, the Vrn-A1, Vrn-B1 and Vrn-D1 genes are dominant for spring growth habit and epistatic to the alleles for winter growth habit. We used DNA markers to determine the VRN-1 genotypes of 43 common wheat cultivars from the Po ...

Our analyses revealed the activity of 8 enzyme systems: 6 polymorphic (PGI, IDH, PX, DIA, PGM, SHD KB) and 2 monomorphic (GOT, ME). The mean number of alleles per locus is 2.12. Nei's genetic distances among populations are small, not exceeding 0.3. M ...
