Varieties of Pulse Crops
for Alberta
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.
Variety testing
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.
