This RIRDC report evaluates variation in several promising cultivars of purslane (Portulaca oleracea) and identifies cultivars of potential for growing and processing in Australia.
The report is initially targeted for use by RIRDC and potential industry participants that may be interested in developing a purslane industry.
Omega-3 fatty acids belong to a group of polyunsaturated fatty acids essential for human growth, development, prevention of numerous cardiovascular diseases and maintenance of a healthy immune system. Purslane (Portulaca oleracea) has recently been identified as the richest vegetable source of omega-3 fatty acids. This study demonstrated that P. oleracea has a potential to be developed as a new vegetable source of omega 3 fatty acid.
This study investigates the effect of genetic variability on poly-unsaturated fatty acids, linolenic (omega 3), in P. oleracea accessions. It also examined the genetic diversity of P. oleracea accessions and correlates the genetic diversity with the fatty acid content of different P. oleracea accessions sampled worldwide.
