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.

J. Plant Sci. 94: 1297–1302. Peace is a hard red spring wheat (Triticum aestivum L.) adapted to the shorter-season wheat-growing regions of the Canadian prairies. Peace was evaluated in the Parkland Wheat Cooperative Test in 1999, 2000 and 2001. Peace exhibited grain yield similar to the check cultivars over 2 yr (1999–2000; Neepawa and Roblin) and over 3 yr (1999–2001; AC Barrie and AC Splendor) Peace matured a day earlier than AC Barrie but was 2 d later than AC Splendor over 3 yr of testing (1999–2001) and was a day later than Neepawa and Roblin over 2 yr of testing (1999–2000). Peace had test weight similar to the check cultivars. Peace was moderately resistant to leaf rust and loose smut and resistant to stem rust including the highly virulent Ug99 race of stem rust and common bunt. Peace was moderately susceptible to Fusarium head blight. Peace meets the end-use quality specifications of the Canada Western Red Spring wheat class.

A detailed analysis of genotype-environment interactions was carried out among yields of six cultivars of hard red spring wheat grown at each of nine locations in five different years. Subdividing the sum of squares for genotype-environment interactions into components due to each cultivar indicated that the Finlay-Wilkinson method of measuring yield stability is of little value for wheat yield in western Canada. Conventional estimates of variance components due to the different types of genotype-environment interaction indicated that all except the genotype-year interaction were significant and important.

Susceptibility And Resistance

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.

Plant Sci. 93: 307–313. Cardale is a hard red spring wheat that meets the end-use quality specifications of the Canada Western Red Spring (CWRS) class. Cardale is a semi-dwarf statured wheat with moderate resistance to Fusarium head blight (FHB). Cardale is derived from the cross McKenzie/Alsen. Cardale was found to be adapted to the eastern wheat growing regions of the Canadian prairies as represented in the Central Bread Wheat Cooperative (CBWC) Registration Test in 2008, 2009 and 2010. In comparison with the check cultivars, Cardale was significantly lower yielding than Unity VB, but overall similar to McKenzie and 5603HR. Cardale matured at the same time as 5603HR, but significantly later (1.5–2.5 d) than the other check cultivars. The plant stature of Cardale was significantly shorter (7–13 cm) than all of the checks, and Cardale had significantly lower lodging scores (0.5–0.7 units) than all of the checks except for CDC Teal. The test weight of Cardale was significantly lower (0.4–0.8 kg hL−1) than that of McKenzie and Unity VB but similar to the other three checks. Cardale expressed resistance to leaf rust and stem rust and moderate resistance to FHB. Disease reactions for common bunt and loose smut were variable but suggested susceptibility and intermediate resistance, respectively. Cardale had preharvest sprouting resistance similar to the best checks McKenzie, Unity VB and 5603HR and significantly better than the poor check CDC Teal in three different determinations. The end-use suitability attributes of Cardale were within the range of the checks except for slightly higher water absorption due to slightly harder kernels (lower particle size index) that led to slightly higher starch damage which occurs during milling.

Harvest is a hard red spring wheat that meets the end-use quality specifications of the Canada Western Red Spring wheat class. Harvest is adapted to the wheat growing regions of the Canadian prairies based on data from the Central Bread Wheat Cooperative Registration Test conducted in 1998, 1999 and 2000 and grown in Manitoba and Saskatchewan. The overall grain yield of Harvest was significantly higher compared with the check cultivars Neepawa, Roblin, AC Majestic and AC Barrie, but yielded significantly less than the check cultivar McKenzie. Harvest matured similar to McKenzie and Neepawa, 1 d later than Roblin, 1 d earlier than AC Barrie and significantly earlier than AC Majestic. Harvest was significantly shorter than the check cultivars and had the lowest lodging scores. The test weight of Harvest was similar to McKenzie and AC Barrie and significantly higher than Neepawa, Roblin and AC Majestic. Harvest demonstrated moderate resistance to leaf rust and loose smut and very good resistance to stem rust. Resistance to common bunt was fair, similar to Neepawa and AC Barrie. Resistance to Fusarium head blight was similar to the susceptible check Roblin and poorer than the other checks. Harvest had very good preharvest sprouting resistance with lower sprouting scores than the best check in 2 of 3 years of testing, and it maintained its falling numbers after natural or artificial weathering of spikes. End-use quality tests indicated that Harvest was within the range of the checks for most end-use quality traits.

Glencross is a hard red spring wheat (Triticum aestivum L.) adapted to the wheat-growing regions of the Canadian Prairies, particularly where orange blossom wheat midge is a production constraint. Glencross was evaluated in the High Yielding Red Wheat Cooperative Test in 2004, 2005, and 2006. Glencross had grain yield similar to the Canada Western Extra Strong (CWES) checks, Glenlea and CDC Rama, as well as the Canada Western Red Spring check, Superb; however, Glencross was significantly (P < 0.05) earlier maturing than all checks by 3 (Superb) to 4 (Glenlea and CDC Rama) days. Glencross had plant height and lodging scores similar to the CWES checks, Glenlea and CDC Rama, but was significantly taller and had significantly higher lodging scores compared with the CWRS check, Superb. Glencross was moderately resistant to moderately susceptible to leaf rust but was highly resistant to stem rust and loose smut. Glencross showed an intermediate reaction to common bunt and was similar to the susceptible checks for Fusarium head blight. Glencross is the first CWES cultivar with resistance to the orange blossom wheat midge (Setodiplosis mosellana Géhin). Glencross demonstrated end-use quality suitable for all grades of the Canada Western Extra Strong wheat class.

Unity is a hard red spring wheat that meets the end-use quality specifications of the Canada Western Red Spring class. Unity is the first spring wheat cultivar registered in Canada that contains the antibiosis resistance gene Sm1, which produces a product that reduces the palatability of developing seeds to wheat midge larvae (Sitodiplosis mosellana Géhin). Unity is a partial backcross derivative of McKenzie, using Clark as the donor of the Sm1 gene for midge resistance. Unity was found to be adapted to the eastern wheat growing regions of the Canadian prairies as represented in the Central Bread Wheat Cooperative Registration Test in 2004, 2005 and 2006. For registration testing, the performance of Unity was estimated using the varietal blend Unity VB, which consisted of 90% Unity and 10% Waskada. In comparison to the check cultivars (Katepwa, McKenzie, CDC Teal, AC Barrie, and Superb), Unity was the highest yielding cultivar overall; although not significant, Unity was 5% higher yielding than McKenzie. Unity matured significantly later than Katepwa and significantly earlier than Superb. Unity had significantly shorter plant stature than Katepwa and significantly taller stature than Superb. Unity had significantly greater lodging scores than AC Barrie and Superb. The test weight of Unity was significantly higher than the best check: 0.9 kg hL-1 higher than McKenzie. Unity expressed resistance to leaf rust, stem rust and common bunt, intermediate resistance to loose smut, and susceptibility to fusarium head blight. Unity had preharvest sprouting resistance with an overall sprouting score similar to the best checks McKenzie and Superb. Unity also maintained its falling numbers following natural or artificial weathering of spikes. The end-use suitability attributes of Unity were similar to the recurrent parent McKenzie for all traits except amylograph viscosity which was significantly higher than all checks except Superb.
