“…The gene carried by RL5407 that controls resistance to races T13 and L7 was not linked with the gene conferring resistance to race T1 (Table 8). However, the relationship of these genes to the named Bt genes (Schaller et al 1960;Waud and Metzger 1970;Metzger and Silbaugh 1971;Metzger et al 1979;Goates 1996) is still unknown.…”

“…Knowledge of the nature and number of genes in resistant sources facilitates disease resistance breeding by allowing better estimates of population size and the most effective generation to start selection. Past genetic studies on the inheritance of common bunt resistance, in various crosses, showed that its genetic control was due to a single gene (Smeltzer 1952;Metzger and Silbaugh 1971;Singh and Chopra 1986;Goates 1996) or two genes (Schaller et al 1960;Metzger et al 1979). The study by Knox et al (1998) on common bunt resistance reported a major gene in both doubled haploid and random inbred populations.…”

He, C. and Hughes, G. R. 2003. Inheritance of resistance to common bunt in spelt and common wheat. Can. J. Plant Sci. 83: 47-56. Common bunt causes yield loss and reduces grain quality in both common and durum wheats in western Canada. Since the most cost-effective method of control is the use of host resistance, this study was conducted to provide information on the genetic control of bunt resistance in three potentially new sources: common wheat cultivar Triple Dirk and spelt wheat cultivars RL5407 and SK0263. The segregating populations from the three crosses Laura/Triple Dirk, Laura/RL5407 and Genesis/SK0263 were evaluated for common bunt resistance in the field for races T1, T13 and L7 and in the greenhouse for race T1. Genetic analysis indicated that Triple Dirk may carry a major gene controlling resistance to each of the bunt races T1, T13 and L7. The spelt wheat RL5407 may carry a major gene for resistance to both races T13 and L7 or genes conditioning resistance to T13 and L7 that are closely linked, and an additional major gene for resistance to race T1. The two major genes carried by RL5407 are believed to be different. SK0263 possibly carried two major genes for resistance to race T1. The disease data in F 1 and F 2 generations did not show any dominance for bunt resistance to race T1 in any of the three crosses. From crosses involving Triple Dirk, RL5407 and SK0263, selection of breeding lines highly resistant to common bunt can be effective in the progenies due to the nature of nondominance and one-or two-gene controlled resistance.Kew words: Wheat, common bunt, Triticum sp., Tilletia sp. et Genesis/SK0263 pour voir si elles résistaient aux races T1, T13 et L7 de la carie au champ et à la race T1 en serre. L'analyse génétique révèle que Triple Dirk pourrait porter un gène important codant la résistance aux races T1, T13 et L7. La variété d'é-peautre RL5407, quant à elle, possèderait un gène majeur de résistance aux races T13 et L7 ou des gènes étroitement liés, conditionnant cette résistance, ainsi qu'un gène important de résistance à la race T1. On croit que les deux grands gènes de résistance de RL5407 sont différents. Par ailleurs, il se pourrait que SK0263 porte deux gènes majeurs de résistance à la race T1. Selon les données recueillies sur la F 1 et la F 2 , aucun des trois croisements ne présente de gène dominant codant la résistance à la race T1. La sélection de lignées généalogiques très résistantes à la carie du blé parmi les hybrides de Triple Dirk, de RL5407 et de SK0263 pourrait s'avérer efficace puisque la résistance n'est pas codée par un gène dominant ou résulte de l'action d'un seul ou de deux gènes.

“…Chemical treatment of the seed is not considered to be the best choice to control this disease because of the cost of seed treatment and its potentially adverse effects on the environment. However, genetic resistance has been used successfully to control common bunt of wheat (Schaller et al 1960, Metzger et al 1979, Goates 1996.…”

Common bunt caused by Tilletia tritici and T. laevis has occurred worldwide and reduces yield and quality in common and durum wheats. The development of DNA markers linked to bunt resistance to race T1 in the cross, ‘Laura’(S) ×‘RL5407’ (R), was carried out in this study based on the single head derived F4:5 and single seed derived F4:6 populations. Bulked segregant analysis was used to identify two random amplified polymorphic DNA (RAPD) markers linked to the gene for resistance to race T1 in the spelt wheat ‘RL5407′. The two markers identified, UBC548590 and UBC274988, flanked the resistance gene with a map distance of 9.1 and 18.2 cM, respectively. The former was linked in repulsion phase to bunt resistance while the later was in coupling phase. The two RAPD markers and the common bunt‐resistance gene all segregated in Mendelian fashion. Use of these two RAPD markers together could assist in incorporating the bunt‐resistance gene from spelt wheat into common wheat cultivars by means of marker‐assisted selection.
