RESUMO:

Safflower is an annual oilseed possessing oil with potential for use in several sectors, such as biodiesel production, pharmaceutical industry, paint manufacturing, besides ruminants feeding, since it is a product rich in linoleic and oleic acids and proteins. It is characterized as an oilseed plant for oil production, since this specie presents important characteristics such as simple management, similar to existing crops, high oil content, easy adaptation to Brazilian climate and also possibility of sub products generating from oil production to be used in animal feed. The present study evaluated the fatty acid profile of 120 safflower genotypes for oil quality, considering as evaluated characters palmitic, stearic, oleic and linoleic acid content. Means of each character were clustered by using Scott-Knott test (1974) at 1% probability. Considering all characters simultaneously, genetic divergence was estimated by Generalized Mahalanobis Distance (D²ii ́) and the most similar individuals were grouped by Tocher Optimization method and hierarchical grouping method UPGMA. The results indicated significant differences (p < 0.01) for all characters evaluated, evidencing the existence of genetic variability among studied genetic materials. Genotypes that stood out for the four variables analyzed were: PI 369842, PI 392031, PI 401474, PI 401475, PI 405975, PI 532639 and PI 613382. The genetic diversity of evaluated genotypes existing among the four fatty acids evaluated, combined with productive potential, suggests expressive expectations for obtaining promising genotypes in a safflower breeding program.
