b' For varieties with sufficient data, the Overall Yield and performance in each Yield Test Category is expressed relative to the checkTo make effective use of the yield comparison tables, producers should set a realistic yield target for the season and determine if it fits within the Low or High Yield Test categories. This approach facilitates matching of variety choice to expected productivity levels and is similar to that used when making decisions on other levels of inputs. Please note the reported yield levels are from small plot trials, which may be 15 to 20 per cent higher than yields expected under commercial field production. vi. Maturity RatingsVariety maturity is an important consideration, especially in parts of the province where the growing season length is limited. Based on feedback from producers, the six-category scale for maturity (Very Early, Early, Medium, Late, Very Late, Extremely Late) has been replaced with average differences in days, relative to the check. Be aware these are averages from several years over the vast agricultural production area of Alberta and that growth environment has a tremendous influence on maturity dates. Hot, dry conditions will compress the reported maturity differences just as cool, wet conditions will expand them. For example, a variety of CWRS wheat may mature in 98 days in Lethbridge but take 103 days in Edmonton. Likewise, a variety that is on average two days later maturing across the province may be only one day later in southern Alberta but could be three or more days later in a northern location.vii. Resistance to Pre-harvest SproutingThere are many inter-related genetic, environmental and management factors that influence seed germination prior to harvest.

Seed Size Seed size within a crop kind will vary from variety-to-variety, from location-to-location and within the same variety when grown at different locations. For example, the seed size of a CWRS variety can be as low as 30 g/1,000 seeds under drought conditions, but with excellent moisture seed size for this same variety can be 40-45 g/1,000 seeds. Therefore, to achieve desired plant populations, 56seed.ab.ca seeding volumes must be calculated based on the seed size of'
