The Alberta Regional Variety Testing Trials (RVTs) are a key source of information for the agriculture industry regarding the yield potential and field performance of new pulse varieties.
The trials are managed by a team of research experts to minimize variability. These trials provide unbiased, comprehensive information that helps producers make better cropping decisions and higher profits.
The Alberta RVTs flourished in 2012 thanks to early moisture and mid-summer heat. Seeding was done into good soil moisture conditions and on time. Emergence was uniform. Frequent spring precipitation kept soil well saturated, but never caused flooding conditions except in some parts of the Peace region where soil moisture was rated as excessive. Then, the hot weather of July and August may have reduced field peas yield potential at some locations, possibly due to plants being shallow rooted.
Agronomic and quality data collected at each location include seed yield, plant height, standability at physiological maturity, disease reaction and thousand-seed weight. The RVT trials are arranged in a randomized complete block design, and all tests have four replications per site. Varieties within each table are arranged in alphabetical order.
The check variety for each crop type is determined by the Crop Coordinator and displayed in bold at the top of the table. Cultivar yield data is shown as a per cent of the check, and the station years of testing column is located beside the yield. Caution is advised when interpreting the data with respect to new varieties that have not been fully tested.
The CV stands for coefficients of variation (CV) in the trial and is expressed as a percentage. Large CVs mean a large amount of variation could not be attributed to differences between varieties. The lower the CV, the better the quality of data. The acceptable coefficient of variation for seed yield is 15 per cent.
There were 17 green and yellow pea sites established across Alberta and two sites in Northeastern British Colombia. Sites in Alberta consisted of five green plus two checks (Cooper and CDC Patrick) and five yellow plus a new check (CDC Meadow) cultivars. Only two green and three yellow variety trials failed due to various reasons.
The chickpea and lentil trial design was changed this year. There is only one joined (desi and kabuli) chickpea and one (early and late) lentil trial starting 2012. Nine chickpea varieties plus check (CDC Frontier) were grown at Bow Island, Brooks, Lethbridge and Medicine Hat. All the trials were successfully harvested. Unfortunately the yield results for the trial at Medicine Hat were not added to the database due to unacceptable CV.
It appears 2012 was a good year for growing lentil trials. Nineteen varieties plus a check (CDC Redberry) were successfully grown at Bow Island, Brooks, Lethbridge and Medicine Hat.
Wide row dry bean trials were grown at Bow Island, Lethbridge and Vauxhall, and the narrow row dry bean had two sites: Lethbridge and Vauxhall. There were 12 varieties including checks in both trials, and all were grown under irrigation. The wide row locations had a complete set of data; however, only the Vauxhall data set was included in the database because 112 km/h winds blew the Lethbridge trial all over beyond repair at harvest time.
Again, there were no fababean regional trials grown in 2012 due to no new varieties being registered.
Plant Breeder’s Rights
Varieties displaying a symbol are subject to Plant Breeder’s Rights (PBR). Any unauthorized sale of seed of these varieties is an infringement under the legislation. Under PBR, producers are allowed to save seed of the variety for their own use, to plant on their own farms.
The hard work of all the people who seed, maintain, take field data, harvest and process grain samples from the variety trials must be acknowledged. The research organizations involved in testing are as follows:
As well, the hard work of the crop coordinators, Alberta Pulse Growers staff, Alberta Agriculture and Rural Development staff and pulse breeders who reviewed the results of the testing, updated diseases and other agronomic information is appreciated.

And finally, without financial support, this publication would not be possible. A sincere thank you to the Alberta Pulse Growers Commission for contributing to the Pulse Science Cluster Project that is run under the Agriculture and Agri-Food Canada, Growing Forward Program; to breeders and seed companies for paying testing fees (Alliance Seed Corporation, Crop Development Centre at University of Saskatchewan and FP Genetics Inc.); to the Association of Alberta Co-op Seed Cleaning Plants, the Alberta Seed Growers’ Association and the Ministry of Agriculture and Rural Development. Finally, about two-thirds of the trials were conducted in Alberta producers’ fields, and their cooperation and dedication are much appreciated as well.
