Research Category: Soybean Utilization Year: 2003 Researcher: Peter Pauls and Vaino Poysa Institution: U of Guelph, AAFC Topic: Applying molecular markers to develop low linolenic, lipoxygenase-free soybean line for improved soymilk stability and flavour Funding: $25,000 Research Details: The objectives of the work were to compare the flavour of soymilk produced from the enhanced- stability lines with soymilk produced from conventional food grade lines (like Harovinton) and to use marker assisted selection to introgress the stability characteristics (low linolenic acid, lipoxygenase null) into Harovinton-like varieties. New soybean germplasm developed through a collaborative [Guelph University/ Agriculture Agrifood Canada (Harrow)], Ontario Soybean Growers- funded project that has low levels of linolenic acid and no seed lipoxygenases was tested for its ability to produce soymilk with improved flavour. The results of two taste panels conducted at Guleph and by a soymilk company in Belgium indicated that the new germplasm produced soymilk that tasted better than soymilk from the current variety. Molecular makers for tracking the low linolenic acid lipoxygenase null traits were used to enhance the breeding process for large seeded soybeans with the enhanced stability trait. Ontario Soybean Growers have funded this research as an attempt to increase demand for Ontario soybeans by increasing quality in food grade soybean lines. File:
