Inheritance of resistance to Tilletia indica (Mitra) in synthetic hexaploid wheat Ă—Triticum aestivum crosses uri icon

abstract

  • Inheritance of resistance to Karnal bunt was investigated in the crosses of four resistant synthetic hexaploid wheats (SH; Triticum turgidum x T. tauschii) and two susceptible T. aestivum cultivars. The resistance was dominant or partly dominant over susceptibility. The SH cultivars Chen/T. tauschii (205) and Chen/T. tauschii (224) have single dominant resistance genes which could be allelic to each other. 'Altar 84'/T. tauschii (219) appeared to have two dominant genes for resistance. 'Duergand' T. tauschii (214) possessed two complementary dominant genes for resistance. The work is being extended to involve diverse Karnal bunt-resistant SH and bread wheat cultivars.
