Varieties with resistance genes for races of the Phytophthora root rot organism in Ontario:
: Resistance genes for Phytophthora root rot in Ontario which provide resistance to some races of the pathogen. Rps 1a does not provide protection to most races of the pathogen in Ontario.
: Resistant to some HG types or races of Soybean Cyst Nematode (SCN) in Ontario.
: Varieties with above average protein index. See Protein & Oil Index
: L-LA is a a designation used by seed sponsors to indicate a soybean variety that produces low linolenic acid in the seed
: Roundup Ready™ (Trademark of Monsanto Company)
: Roundup Ready 2 Yield™ (Trademark of Monsanto Company)
: Liberty Link™ (Trademark of Bayer CropScience AG)
Varieties have not been
evaluated for metribuzin tolerance by OSACC. For further information contact seed distributor. The following variety has been reported to OSACC as being Metribuzin Sensitive (MS
Ranking of maturities has been initiated to provide producers with a rating system that is similar to the US soybean industry standards. Rankings are not assigned by OSACC. See Relative Maturity Map
Each soybean seed has a hilum which is the point where it was attached to the pod. Varieties differ in hilum colour and can be either Yellow (Y), Imperfect Yellow (IY), Gray (GR), Buff (BF), Brown (BR), Black (BL), or Imperfect Black (IBL). Hilum colour may also be Light (L). Yellow hilum soybeans are usually the only type accepted for the export market. In certain years discolouration of the hilum of IY varieties can occur and as a result the soybeans may not be acceptable for export markets.
Seeds per Kilogram
This is an estimate of the relative number of seeds of a particular variety in a kilogram of seed based on a 1-2 years of data from all locations where a variety was tested. Since seed size can vary from year to year and from seed lot to seed lot these figures should be used as a rough guide only. The actual seed size reported on each seed lot should be used to calculate seeding rate.
Phytophthora Root Rot % Plant Loss
Based on three year average in a field heavily infested with Phytophthora. Not all races of Phytophthora root rot are found at these sites. The relative ranking of varieties for plant loss may differ in fields that have other races present.
Disease Testing Information
Phytophthora root rot testing is carried out on clay soils infested with common races of Phytophthora at Woodslee.
White Mold variety ratings will be listed on the web at www.Gosoy.ca as they become available .
SCN tests are done in collaboration with variety sponsors and the SCN Resistant Variety Development project. For further information contact firstname.lastname@example.org.
Protein & Oil Index
Protein Index (%) and Oil (%)
is shown on a separate table.
Least Significant Difference (LSD)
The Least Significant Difference (LSD) was determined for each Yield Index column. To compare any two varieties within a column, the yield can be considered the same if the difference between their yield indices is less than or equal to the LSD for that column.
