%X Changes in lipids of three newly developed varieties of rapeseed during seed maturation were studied. Triacylglycerol molecular species, fatty acid composition, whole sterol, and four sterol lipids as well as tocopherol were determined at different maturation stages. It was found that marked variations in some lipids were observed in one variety than the other. Efficient methods of analysis employed in this investigation and the individual lipid components, even in very minor quantities, were accurately detected. Marked varietal changes in lipids compositions during seed maturation manifest themselves, to some extent, in three new rapeseed varieties. Changes in lipids of maturing seeds were interpreted in the frame of probable conversion-interconversion reactions that may occur during seed maturation. Se estudiaron los cambios en los l赤pidos de tres nuevas variedades desarrolladas de colza durante la maduraci車n de la semilla. Las especies moleculares de triacilgliceroles, la composici車n en 芍cidos grasos, los esteroles totales, y cuatro esteroles lip赤dicos, as赤 como tocoferol fueron determinados en diversas etapas de maduraci車n. Se encontraron variaciones m芍s marcadas en algunos l赤pidos en una variedad que en las otras. Los eficientes m谷todos de an芍lisis empleados en esta investigaci車n permitieron detectar con exactitud, incluso en cantidades muy peque as los componentes lip赤dicos individuales. Los cambios varietales marcados en las composiciones lip赤dicas se manifiestaron durante la maduraci車n de la semilla en tres nuevas variedades de colza. Los cambios en l赤pidos de semillas durante la maduraci車n fueron interpretados en el marco de las probables reacciones de conversi車n-interconversi車n que pueden ocurrir durante la maduraci車n de la semilla.
