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 less 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.
Claims19
A Brassica napus plant comrising
- seed having a total glucosinolates content of about 18 μmol/g or less of defatted, air-dried meal;
- the seed yielding oil having an α-linolenic acid content of 7% or less relative to total fatty acid content of said seed and a sulfur content of less than or equal to 3.0 ppm;
- and
- the plant belonging to a line in which these traits have been stabilized for both the generation to which the seed belongs and that of its parent generation.
A Brassica napus plant designated IMC 01 represented by seed deposited with the ATCC and bearing accession number 40579.
A Brassica napus seed yielding canola oil having, when hydrogenated, significantly reduced overall room-odor intensity relative to the overall room-odor intensity of generic canola oil, a significant difference in overall room odor-intensity indicated by a difference of greater than 1.0 obtained in a standardized sensory evaluation.
A Brassica napus comprising oil, which when non-hydrogenated, is significantly reduced in fishy odor intensity relative to the fishy odor intensity of generic canola oil, a significant difference in fishy odor intensity indicated by a difference of greater than 1.0 obtained in standardized sensory evaluation.
A plant produced from the crossing of IMC 01 with an agronomically elite variety of Brassica napus, the plant yielding a seed having a total glucosinolates content of about 18 μmol/g or less of defatted, air-dried meal, said seed yielding extractable oil having (1) an α-linolenic acid content of about 7% or less relative to total fatty acid content of said seed, and (2) a sulfur content of less than or equal to 3.0 ppm.
A process for producing a canola of enhanced commercial utility comprising:
- (a) crossing the Brassica napus IMC 01 with an agronomically elite variety;
- (b) selecting the off-spring of step (a) which yield a seed having a total glucosinolates content of about 18 μmol/g or less of defatted, air-dried meal, said seed yielding extractable oil having (1) an α-linolenic acid content of about 7% or less relative to total fatty acid content of said seed, and (2) a sulfur content of less than or equal to 3.0 ppm.
A method of using the Brassica napus IMC 01 comprising:
- (a) crossing IMC 01 with an agronomically elite variety;
- (b) selecting the off-spring of step (a) which yield a seed having a total glucosinolates content of about 18 μmol/g or less of defatted, air-dried meal, said seed yielding extractable oil having (1) an α-linolenic acid content of about 7% or less relative to total fatty acid content of said seed, and (2) a sulfur content of less than or equal to 3.0 ppm;
- (c) producing sufficient progeny of the seed selected in step (b) to extract oil.
The Brassica napus designated HW 3.001, a progeny line of the cross of IMC 01 with Westar.
An improved vegetable oil extracted from Brassica napus seeds, said seeds having:
- (1) an oil which exhibits following crushing and extraction
- (a) an α-linolenic acid content of 7% or less relative to total fatty acid content of said seed;
- (b) a sulfur content of less than or equal to 3.0 ppm;
- and
- (2) a total glucosinolates content of about 18 μmol/g or less of defatted, air-dried meal.
