Susceptibility and resistance in Canadian spring wheat cultivars to common bunt (Tilletia tritici and T. laevis)

Current western Canadian hard red spring wheat cultivars and their progenitors, inoculated with a composite of Tilletia tritici and T. laevis races, were grown at Lethbridge from 1989 to 1991 and the percentage infection was determined. This study also examined cultivar × environment interaction effects. Ancestral cultivars, such as Red Calcutta 33, Marquis, Thatcher, and their descendants, Canthatch, Park, Neepawa, Manitou, and Cadet, exhibited intermediate levels of bunt resistance. Cultivars including the cultivar Hope in their ancestry, such as Redman, Chris, Katepwa, Columbus, Reward, and Lancer, were highly resistant. Analysis of the environment × cultivar interaction indicated that bunt infection levels in Hope, Redman, and Columbus were stable over environments, but infection which varied according to environment was observed for Katepwa and Reward. The reduction of a number of cultivars including Neepawa, Thatcher, Kenya Farmer, Fortuna, Cadet, and Chris, was unstable across environment. Mexican semi-dwarf cultivars, such as Tobari 66, Potem 70, Cajeme 71, Ciano 67, Sonora 64, Inia 66, and the Canadian cultivars HY320, BW 90, and Laura, were highly susceptible. In general, the level of infection in these cultivars was uniform across environments. The nature of resistance in Canadian cultivars, the high infection levels of some Canadian cultivars and their Mexican semi-dwarf ancestors, and the variation in stability of infection levels of some cultivars across environments are discussed.

AAC Elie hard red spring wheat (Triticum aestivum L.) has grain yield and time to maturity within the range of the checks. AAC Elie has an awned spike, a low lodging score indicative of strong straw, and a short plant stature typical of a semidwarf. These traits were comparable to the check Carberry. AAC Elie expressed resistance to prevalent races of leaf and stem rust, and intermediate resistance to fusarium head blight, yellow rust, common bunt, and loose smut.

A field study involving winter and spring wheat cultivars possessing race-specific and nonspecific resistance to Tilletia tritici and T. laevis was conducted to determine the effect of bunt on culm dwarfing, and the role of culm height in the susceptibility of wheat cultivars. Bunt-induced stunting, ranging from 2.4 to 21%, was observed in 20 of 25 cultivars and the severity was correlated with level of bunt (r = 0.86). Also, there was preferential infection of shorter culms by the bunt fungus and this appeared to be a major factor in the susceptibility of most cultivars in this study. Cultivars possessing moderate to high levels of nonspecific resistance such as Katepwa and Chinook had fewer short culms; these short culms were susceptible. A large proportion of the culms of short-statured or semi-dwarf cultivars such as HY320, Tobari 66, and the soft white spring wheats Fielder and Springfield, fell into the shortest height classes; uniformly these were highly susceptible to bunt infection. Laura and Roblin, cultivars of conventional height, had a large proportion of short culms and these were highly susceptible. Red Bobs 222 and HY355 also exhibited high levels of bunt in the taller culms. Cultivars possessing race-specific resistance such as the durum wheats and BW553 had low levels of infection across the culm height classes. Cultivar variation in susceptibility to bunt within each of the different culm height classes also was observed. The possible implications of the effect of preferential bunting of short culms on development in short-statured or semi-dwarf wheats are discussed. Key words: Stinking smut, Norin 10/Brevor

In 2005, 2006 and 2007 nineteen, eight and nine spring wheat cultivars, respectively, were tested in field trials for resistance to common bunt after inoculation with bunt teliospores. Nine spring wheat cultivars were tested in a greenhouse under favourable conditions for the bunt infection. Bunt incidence in the field trials varied between 0% and 38.7%, in the greenhouse between 52.9% and 100%. The results of individual cultivars and years fluctuated. A reduction in plant height, ear length, root system and increased tillering were registered in the inoculated plants. Spots on the leaves of inoculated plants were observed in three out of the four greenhouse experiments.

Goyal A., Beres, B. L., Randhawa, H. S., Navabi, A., Salmon, D. F. and Eudes, F. 2011. Yield stability analysis of broadly adaptive triticale germplasm in southern and central Alberta, Canada for industrial end-use suitability. Can. J. Plant Sci. 91: 125–135. Triticale (×Triticosecale Wittmack) is a cereal crop with high grain yield and biomass potential, which are traits desired in biorefinery processes that currently utilize wheat (Triticum aestivum). This study was conducted to evaluate the performance of introduced germplasm for its adaptability to selected Canadian prairie agroecosystems, and to benchmark both introduced and registered triticale lines against hard red spring wheat. To investigate the genotype×environment interaction effects on the performance of triticale genotypes, 30 genotypes (27 triticale; 3 hard red spring wheat) were grown in three environments for 3 yr (2005–2007) in southern and central Alberta, Canada. Variance due to genotypes, years, locations, and their interactions were studied by employing several stability analysis models. Site Regression Model (SREG) and GGE biplot analysis were conducted to rank the relative yield performance of cultivars and to identify stable genotypes. Triticale consistently produced higher grain and biomass than hard red spring wheat, but some lines were high in pentosan content, produced low test weight, and possessed unacceptable growing degree day requirements. However, several of the introduction lines displayed superior trait performance and high stability. Five advanced to “C” level registration testing with one subsequently recommended for registration. The results provide evidence that some of the global triticale germplasm are well-suited to the production environments of the Canadian prairies, and that triticale has potential to be the ideal cereal platform for future technological and biorefinery end-use applications.
