Abstract
The invention relates to improved Brassica species, including Brassica juncea, improved oil and meal from Brassica juncea, methods for generation of such improved Brassica species, and methods for selection of Brassica lines. Further embodiments relate to seeds of Brassica juncea comprising an endogenous oil having increased oleic acid content and decreased linolenic acid content relative to presently existing commercial cultivars of Brassica juncea, seeds of Brassica juncea having traits for increased oleic acid content and decreased linolenic acid content in seed oil stably incorporated therein, and one or more generations of progeny plants produced from said seeds.
Claims24
A Brassica juncea plant whose seeds have an endogenous fatty acid content comprising at least 70.0% oleic acid by weight and less than 5.0% linolenic acid by weight.
An oil in seeds of a Brassica juncea variety, said oil having a fatty acid content comprising at least 70.0% oleic acid by weight and less than 5.0% linolenic acid by weight.
A method of producing a Brassica juncea plant whose seeds have an endogenous fatty acid content comprising at least 70.0% oleic acid by weight and less than 5.0% linolenic acid by weight, comprising:
- introducing into said Brassica juncea plant, through traditional crossing methods, one or more nucleic acid sequences selected from the group consisting of a mutated fad2a nucleic acid sequence, a mutated fad2b nucleic acid sequence, a mutated fad3a nucleic acid sequence, a mutated fad3a nucleic acid sequence, and a mutated fad3b nucleic acid sequence.
Meal from seeds of a Brassica juncea plant having an endogenous fatty acid content comprising at least 70.0% oleic acid by weight and less than 5.0% linolenic acid by weight.
Seeds from a Brassica juncea plant, said seeds incorporating one or more non-recombinant fad2 and fad3 genes from one or more genomic components of a Brassica aa and/or Brassica bb genome, said seeds producing an oil having a fatty acid content comprising at least 70.0% oleic acid by weight and less than 5.0% linolenic acid by weight, said genes introduced into said Brassica juncea plant by conventional breeding methods.
One or more generations of progeny plants produced from at least one of the seeds of claim 20, said progeny plants producing seeds which incorporate said one or more non-recombinant fad2 and fad3 genes and which produce an oil having a fatty acid content comprising at least 70.0% oleic acid by weight and less than 5.0% linolenic acid by weight.
A seed oil produced in seeds of a crop of non-transgenic Brassica juncea plants, said seed oil having a fatty acid content comprising at least 70.0% oleic acid by weight and less than 5.0% linolenic acid by weight.
A crop of Brassica juncea producing seeds having an endogenous oil content which averages, across the crop, at least 70.0% oleic acid by weight and less than 5.0% linolenic acid by weight.
A Brassica juncea cultivar producing seeds having, on average, an endogenous oil content which averages, across the crop, at least 70.0% oleic acid by weight and less than 5.0% linolenic acid by weight.
