Inheritance of resistance to Tilletia indica (Mitra) in synthetic hexaploid wheat x Triticum aestivum crosses.

Inheritance of resistance to Karnal bunt was investigated in the crosses of four resistant synthetic hexaploid wheats (SH; Triticum turgidum × 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.
