Variety testing | Plant Breeders' Rights | Acknowledgements
The Alberta Regional Variety Testing (RVT)Trials 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.
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. 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 Co-ordinator and displayed in bold at the top of the table. Cultivar yield data is shown as 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. Acceptable coefficient of variation for seed yield is 15 per cent.
There were 18 green and yellow pea sites established across Alberta and two sites in northeastern British Colombia. Sites in Alberta consisted of four green plus a check (CDC Patrick) and five yellow plus a check (CDC Meadow) cultivars. Only three green and four yellow variety trials failed due to various reasons.
Nine chickpea varieties plus a check (CDC Frontier) were grown at Bow Island, Brooks, Lethbridge and Medicine Hat. All the trials were successfully harvested. Yield results for the trial at Medicine Hat were not added to the database due to high CV.
The year 2013 was a good one for growing lentil trials. Twenty varieties plus a check (CDC Redberry) were grown at Bow Island, Brooks, Lethbridge and Medicine Hat. Yield results for the trial at Medicine Hat were not added to the database due to high CV.
Wide row dry bean trials were grown at Bow Island, Lethbridge and Vauxhall, and the narrow row dry beans were grown at two sites, Lethbridge and Vauxhall. There were 12 varieties including checks in both trials and all grown under irrigation. The wide row locations had a complete set of data; however, only the Lethbridge narrow data set was included in the database.
The fababean regional trials were resumed in 2013 after five years of no trials. Four fababean varieties plus a check (Snowbird) were grown at nine locations across Alberta. Results of all the trials except the Barrhead site, which was hailed out, were added to the database.
And new crop, soybean, has been added to the Regional Variety Testing program this year. Sixteen soybean varieties plus a check (NSC Warren) were grown at eight funded and two volunteer sites. Seven sites were harvested; however, only five locations were added to the database. CVs for the other two trials were too high.
Plant Breeder’s Rights
Varieties displaying the 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 the testing are as follows:
As well, the hard work of the crop co-ordinators, 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.

A sincere thank you goes also to the following:
Finally, more than two thirds of the trials were grown at Alberta producers’ fields, and their co-operation and dedication are sincerely appreciated as well.
