dc.description.abstractSoybean (Glycine max L.) is the most widely grown legume crop in the world, and in Saskatchewan soybean success depends on fitting this warm-season crop to a cool, dry and short growing season. In 2019 we grew twenty-four conventional and GMO soybean cultivars (varieties) from industry and breeding programs across four locations (Rosthern, Saskatoon, Outlook (irrigated), and Kamsack) in SK. Our objective was to evaluate yield and its components of Maturity Group 0, 00, and 000 cultivars representing the range of early maturity currently available for western Canada. We found significant variation in plant height, number of main stem nodes, number of branches, main stem pods, branch pods, above-ground biomass, and harvest index (the ratio of grain weight to above-ground biomass). Genotype x environment interaction was mostly non-significant but the four locations significantly varied for all traits. Rosthern had larger plants with more nodes, more branches, greater seed number per area and harvest index. Surprisingly, Kamsack and Saskatoon had lower values for most traits. Tall cultivars with more nodes generally had lower harvest indices. Cultivars with greater seed yield had more branches, and hence more pods. This preliminary study highlights the potential of soybean production under Saskatchewan environments although more years and environments are needed to identify the best adaptation traits.en_US
