Rl. Villareal et al., INHERITANCE OF RESISTANCE TO TILLETIA-INDICA (MITRA) IN SYNTHETIC HEXAPLOID WHEAT X TRITICUM-AESTIVUM CROSSES, Plant breeding, 114(6), 1995, pp. 547-548
Inheritance of resistance to Karnal bunt was investigated in the cross
es of four resistant synthetic hexaploid wheats (SH; Triticum turgidum
x T. tauschii) and two susceptible T. aestivum cultivars. The resista
nce was dominant or partly dominant over susceptibility. The SH cultiv
ars Chen/T. tauschii (205) and Chen/T. tauschii (224) have single domi
nant 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 gen
es for resistance. The work is being extended to involve diverse Karna
l bunt-resistant SH and bread wheat cultivars.
