Conola variety IMC 02 with reduced linolenic acid

Abstract

A canola line has been stabilized to produce seeds having an α-linolenic acid content of less than that of generic canola oil, more preferably lass than or equal to about 7% α-linolenic acid relative to total fatty acid content of said seed and a total glucosinolate content of less than 18 μmol/g of defatted meal, more preferably less than or equal to about 15 μmol/g of defatted meal. This canola line has reduced sulfur content of less than or equal to 3.0 ppm, improved sensory characteristics and increased oxidative stability.

1 . A canola plant line designated IMC 02 and having American Type Culture Collection (ATCC) Accession No. PTA-6221.  
     
     
         2 . Progeny of the canola plant line of  claim 2 , said progeny producing seeds having an α-linolenic acid content of from about 1.6 to about 7% and an aliphatic and indolyl glucosinolate content of about 13 μmol or less per gram of deFatted, air-dried meal.  
     
     
         3 . The progeny of  claim 2 , wherein said α-linolenic acid content is from about 1.9% to about 4.1%.  
     
     
         4 . Seeds of the progeny of  claim 2 , said seeds having said α-linolenic acid content and said aliphatic and indolyl glucosinolate content.  
     
     
         5 . Plants of the progeny of  claim 2 , seeds of said progeny having said α-linolenic acid content and said aliphatic and indolyl glucosinolate content.  
     
     
         6 . Canola meal extracted from the seeds of  claim 2 , said canola meal having an aliphatic and indolyl glucosinolate content of about 13 μmol or less per gram of defatted, air-dried meal.  
     
     
         7 . The progeny of  claim 2 , wherein said α-linolenic acid content is from about 1.6 to about 1.8% seeds have an ______  
     
     
         8 . Seed of a  Brassica napus  canola plant line, said seed having an α-linolenic acid content of from about 1.6 to about 7% and an aliphatic and indolyl glucosinolate content of about 13 μmol or less per gram of defatted, air-dried meal, wherein said plant is a descendant of a cross of a plant line designated IMC 02 and having ATCC Accession No. PTA-6221 with a second non-IMC 02  Brassica napus  line.  
     
     
         9 . Progeny of the seed of  claim 8 , said progeny producing seeds having an α-linolenic acid content of from about 1.6% to about 7% and an aliphatic and indolyl glucosinolate content of about 13 μmol per gram of meal.  
     
     
         10 . The seed of  claim 8 , wherein said α-linolenic acid content is from about 1.9% to about 4.1%.  
     
     
         11 . Canola meal extracted from the seed of  claim 8 , said canola meal having an aliphatic and indolyl glucosinolate content of about 13 μmol or less per gram of meal.  
     
     
         12 . The seed of  claim 8 , wherein said α-linolenic acid content is from about 1.6% to about 2.8%.  
     
     
         13 . The seed of  claim 8 , having an aliphatic glucosinolate content of about 3.7 to about 6.3 μmol per gram of meal.  
     
     
         14 . The seed of  claim 8 , wherein said seed has an average aliphatic glucosinolate content of about 4.9 μmol per gram of meal.
