Wheat is Canada's largest crop with most of the production in the western Canadian prairie provinces of Manitoba, Saskatchewan and Alberta. Since wheat production started in western Canada, over 100 yr ago, market classes of hexaploid spring bread wheat (Triticum aestivum L.) were the dominant type of wheat, although production of durum wheat [Triticum turgidum L. ssp. durum (Desf.) Husn.)] has grown significantly over this period, and hexaploid winter wheat was grown on a relatively small portion of the wheat area. Within hexaploid wheat there has been diversification into a number of market classes based on different end-use quality criteria. The predominant spring bread wheat class has been the Canada Western Red Spring (CWRS) class. A few cultivars were grown extensively over a long period of time, such as the CWRS wheat Thatcher, which was the dominant cultivar from 1939 to 1968, and Kyle, which was the leading Canada Western Amber Durum (CWAD) cultivar from 1988 to 2004. Other cultivars dominated particular wheat classes for many years such as Glenlea, Canada Western Extra Strong (CWES) spring wheat and Norstar, Canada Western Red Winter (CWRW) wheat. The reasons for newer cultivars replacing older cultivars include improvements in grain yield, resistance to stem rust (Puccinia graminis Pers.:Pers. f. sp. tritici Eriks. & E. Henn.), leaf rust (Puccinia triticina Eriks.), and other diseases, resistance to wheat stem sawfly (Cephus cinctus Nort.), enhanced end-use quality, and other agronomic characteristics such as lodging resistance. Cultivars with improved pest resistance were often rapidly adopted, such as Thatcher and Selkirk, in response to the stem rust epidemics in the 1930s and 1950s, and Rescue and Lillian in response to wheat stem sawfly epidemics in the 1940s and 2000s. Improved grain yield led to the rapid increase of many cultivars including Marquis in the 1910s and 1920s, Neepawa, Wascana and Wakooma in the 1970s, AC Barrie in the 1990s, and Superb in the 2000s. Increased breeding efforts recently have led to many more highly adapted cultivars and subsequently more diverse wheat production. Wheat classes and cultivars in the prairies continue to improve and diversify to meet the challenges of the marketplace and the production concerns of wheat growers.

. 2010. Harvest hard red spring wheat. Can. J. Plant Sci. 90: 503Á509. 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. Harvest s'ave`re mode´re´ment re´sistant a`la rouille de la feuille et au charbon nu, et re´siste tre`s bien a`la rouille de la tige. La varie´te´re´siste assez bien a`la carie, comme Neepawa et AC Barrie. Sa re´sistance a`la bruˆlure de l'e´pi par Fusarium est similaire a`celle du te´moin sensible Roblin et infe´rieure a`celle des autres te´moins. Harvest re´siste tre`s bien a`la germination sur pied, avec une note supe´rieure a`celle des meilleurs cultivars te´moin, deux anne´es sur trois. Harvest conserve son indice de Hagberg meˆme apre`s l'alte´ration sur pied naturelle ou artificielle des e´pis. Les tests de qualite´pour l'usage final indiquent que Harvest se situe dans la fourchette des cultivars te´moin pour la majorite´des parame`tres qualitatifs. For personal use only.

Wheat seed-borne diseases are among the major constraints reducing crop yield and the quality of seed and grain. In this study we aimed to evaluate the type and prevalence of fungal seed-borne diseases in Tajik wheat seed samples. Particular emphasis was given to common bunt resistance in advanced wheat breeding materials. Furthermore, we aimed to identify options for improving the seed quality. Seed samples collected from two different locations in Tajikistan were tested by conventional seed-health testing methods for presence of seed-borne diseases. Nineteen advanced wheat breeding lines and three varieties collected from the Tajik wheat breeding program were screened using an artificial inoculation test for their response to common bunt. Significant differences were found between the locations and genotypes concerning presence of common bunt and black point. Fourteen fungal species, where most of them are pathogenic for wheat, were identified in the seed samples. Tilletia laevis, T. tritici, Bipolaris sorokiniana, Stemphylium spp., and Drechslera spp. were the major pathogenic fungi observed in collected wheat samples. Common bunt was predominantly represented by T. laevis. No strong resistance was found in the studied Tajik wheat material, although a low percentage of infection was found in one line (SHARK/ F4105W2.1), while the material was evaluated for common bunt resistance. In managing seed-borne diseases, breeding of resistant varieties should be given a priority, while cultural practices such as preventing contamination and monitoring seed health status should also be considered, as a last resort the use of chemical seed treatments are advised.
