Soybean cultivars

 

Soya-North Co. develops non-GM soybean cultivars MG 00 and 000.
Our staff is occupied with soybean breeding since 1992. A theoretical base for breeding process are: model of soybean variety, approaches to parental pairs selection, methods of evaluation and selection in hybrid populations elaborated by company staff.
Comparatively large attention in our studies is paid to the ‘construction’ of morphological habit. A number of research works was carried to identify agronomic value of growth type, mode of branching, and other traits under local conditions.
Knowledge of photoperiod response is sufficient for early soybean breeding. It allows modification of maturity date and optimizing ‘yield / earliness’ relationship. It has been shown by us that phenological stages interrelations affect drought resistance. That’s why our company promotes photoperiod response genetics with an implement of molecular markers for a number of years.
A key position in breeding is germplasm collecting and analysis. Our company maintains a germplasm collection including about 300 entries of diverse origin (from Canada to Japan). Accession analysis data are accumulated and statistically treated in a database. This knowledge is used to improve future cultivars models that are constructed with the help of various mathematical and genetic methods. To work out a new cultivar model, we try not to join the best parental properties only, but take into account their compatibility, impact on yield stability and genotype – environment interaction.
Our scientific publications are listed here.

 

Our cultivars

We propose well known cultivars as Prypiat and Yaselda, as well as new varieties Oressa and Volma developed in the network of a new breeding program of Soya-North Co.
High yielding and lacking technological drawbacks Oressa and Volma provide maximum yield for their maturity. Due to a weak E7 gene of photoperiod response and additional lateral buds they perfectly fit the climate. Oressa and Volma are especially responsive to the improvement of the environment because they are able to produce 14 mainstem productive nodes and more. High adaptability allows growing these varieties in 70 cm rows.
Prypiat is the best choice for expansion towards North, as well as for regions subjected to drought. Combining drought and lodging resistances results in a broad adaptability of this cultivar. Prypiat can be grown to 54o N latitude. Its stable yields combined with increased protein rate (reaching 46-47%) have caused positive references of Russian specialists and producers.
