[Allelic Composition in the VRN-A1, VRN-B1, and VRN-B3 Genes of Double Haploid Lines of Hexaploid Triticale].
2015
Vernalization genes are associated with the adaptation capability, heading dates, and yield potential of grain crops. The allelic composition in the Vrn-A1, Vrn-B1, and Vrn-B3 genes was defined in 42 lines of double haploids of hexaploid triticale, which were produced through in vitro anther culture. Two alleles (Vrn-A1a and vrn-A1) were found at the Vrn-A1 locus and three alleles (Vrn-B1a, Vrn-B1c, and vrn-B1) were found at the Vrn-B1 locus. All double haploids carried the recessive allele at the Vrn-B3 locus. Twelve lines of spring triticale were selected, and they were characterized by an allelic composition associated with early maturity and high potential of grain yield.
