  • Title: [Identification of genes that promote awnedness in the Triticum aestivum/Aegilops umbellulata introgressive line].

    Abstract:
    Genetic analysis of Triticum aestivum/Aegilops umbellulata introgressive line for the character ear awnedness has been realized. According to the studying the lines and hybrids for the characters awnedness and electrophoresis spectra of microsatellite components the digenic model for control of awnedness is suggested. The model supposes participation of gene--inhibitor of awnedness B1 (5AL) and gene--promoter of awnedness Awn1 in chromosome 6U of Aegilops umbellulata. Chromosome 5A of the awned line is rearranged relative to the same chromosome of the Aurora genotype. The distance between the Xwmc705-5AL SSR-locus and rearranged fragment or locus B1/b1 is determined as 15,5 cM.
