Abstract

P>Oleic acid content was increased from approximately 5-11% to 80-86% in Guizotia abyssinica (L. f.) Cass. materials from Ethiopia after repeated selection and breeding. Achenes collected from Ethiopia were screened for elevated oleic acid content by half seed technique. The starting materials for breeding were nine plants selected from among 272 seeds analysed and having an average oleic acid content of approximately 21% which is considered to be high compared with the 5-11% reported earlier for niger materials of Ethiopian origin. It was observed that the oleic acid content steadily increased after each round of selection and breeding. The percent oleic acid in the seed oil increased to an average of 35.2% and 53.4% after the first and second round of breeding, respectively and ultimately to over 80% after the third round of breeding. It was also observed that the percent oleic acid in the oil stabilizes and the plants breed true when the oleic acid content in the parental seeds was above 79%.
