The improvement of Borage as a commercial source of gamma-linolenic acid
Objectives: TThe project seeks to increase the commercial yield of GLA from borage, through selection and breeding for improvements in plant type, such as determinate growth, harvestability and yield of oil and GLA among introduced lines.
Work undertaken to date: The Tasmanian Institute of Agricultural Research, in conjunction with Willala Agricultural Pty Ltd, have acquired borage seed lines from individuals and companies within Australia, Europe and America with interests in borage production. As opportunities have arisen, further acquisition of genetic material bas continued. These lines have been maintained in isolated plantings. Since 1999-2000 these lines have also been evaluated in replicated trials. The major part of this project's work to date has been further replicated experiments to gain comparative data on promising lines, as they are identified and newly acquired lines. Overall, seed yields and oil content tend to be inversely proportional but show some heritability. GLA percentages of oil have been consistent through experiments and also show heritability. Lines performing best under local conditions have been selected and these have been crossed in an initial program to provide improved lines for the industry stakeholder. While the initial four-year period of work ended in June, continuation of the selection program is under discussion.
