Abstract:	Modification of the fatty acid composition of soybeans has been an important objective of plant breeders for some time. Elevation of the saturated fatty acids palmitic and stearic acids would improve the crystal structure of plastic fats, reduce the requirement for hydrogenation in production of margarines and shortenings, and improve the oxidative stability of soybean oils used for frying. However, modified soybean seeds must also display good agronomic characteristics. In this study, vigour of soybean seedlings with elevated stearate or elevated or reduced palmitate were compared with normal seedlings for several markers of vigour: germination, seedling growth rate and leachate conductivity. In general, seeds with altered compositions did well in these tests, but their overall vigour was negatively correlated with percentages of stearate or palmitate in various lipid classes.
