Plants, seeds and oils having an elevated total monounsaturated fatty acid content

Abstract

Plants, seeds and oils having a total long chain monounsaturated content of at least about 82% and an erucic acid content of at least about 15% are described. Methods for producing plants having the profiled fatty acid content are also described.

         1 . A Brassica plant producing seeds having a long chain monounsaturated fatty acid content of at least about 82% and an erucic acid content of at least about 15% based on total fatty acid composition.  
     
     
         2 . The plant of  claim 1 , said seeds having an oleic acid content of at least about 37% based on total fatty acid composition.  
     
     
         3 . The plant of  claim 1 , said seeds having an eicosenoic acid content of at least about 14% based on total fatty acid composition.  
     
     
         4 . The plant of  claim 1 , wherein said monounsaturated fatty acid content is from about 85% to about 90%.  
     
     
         5 . The plant of  claim 4 , said seeds having an oleic acid content of at least about 42% based on total fatty acid composition.  
     
     
         6 . The plant of  claim 5 , wherein said oleic acid content is from about 47% to about 56%.  
     
     
         7 . The plant of  claim 4 , said seeds having an erucic acid content of from about 17% to about 31% based on total fatty acid composition.  
     
     
         8 . The plant of  claim 4 , said seeds having an eicosenoic acid content from about 15% to about 21% based on total fatty acid composition.  
     
     
         9 . The plant of  claim 1 , said seeds having a saturated fatty acid content of less than about 7% based on total fatty acid composition.  
     
     
         10 . The plant of  claim 1 , said seeds having a polyunsaturated fatty acid content of less than about 11% based on total fatty acid composition.  
     
     
         11 . Progeny of the plant of  claim 1 , said progeny having said long chain monounsaturated fatty acid content and said erucic acid content.  
     
     
         12 . A Brassica seed oil having a long chain monounsaturated fatty acid content of at least about 82% and an erucic acid content of at least about 15% based on total fatty acid composition.  
     
     
         13 . The oil of  claim 12 , said oil having an oleic acid content of at least about 37% based on total fatty acid composition.  
     
     
         14 . The oil of  claim 12 , said oil having an eicosenoic acid content of at least about 14% based on total fatty acid composition.  
     
     
         15 . The oil of  claim 12 , wherein said monounsaturated fatty acid content is from about 85% to about 90%.  
     
     
         16 . The oil of  claim 15 , said oil having an oleic acid content of at least about 42% based on total fatty acid composition.  
     
     
         17 . The oil of  claim 16 , wherein said oleic acid content is from about 47% to about 56%.  
     
     
         18 . The oil of  claim 15 , said oil having an erucic acid content of from about 17% to about 31% based on total fatty acid composition.  
     
     
         19 . The oil of  claim 15 , said oil having an eicosenoic acid content from about 15% to about 21% based on total fatty acid composition.  
     
     
         20 . The oil of  claim 12 , said oil having a saturated fatty acid content of less than about 7% based on total fatty acid composition.  
     
     
         21 . The oil of  claim 12 , said oil having a polyunsaturated fatty acid content of less than about 11% based on total fatty acid composition.  
     
     
         22 . The oil of  claim 21 , wherein said polyunsaturated fatty acid content is less than about 9%.  
     
     
         23 . A method of producing a plant having a long chain monounsaturated fatty acid content of at least about 82% and an erucic acid content of at least about 15% based on total fatty acid composition, said method comprising the steps of crossing a first plant line with a second plant line and selecting progeny of said cross having said monounsaturated content, wherein said first plant line has an erucic acid content of at least about 45% based on total fatty acid composition and said second plant line has an oleic acid content of at least about 84% based on total fatty acid composition.
