Inheritance of Quality and Quantity of Seed-Oil in Safflower (Carthamus tinctorius L.)¹

A safflower introduction from India and the variety ‘N-10’ were crossed reciprocally to produce F₁, F₂, F₃ and backcrossed generations. The same 2 lines were grafted reciprocally. Seed samples from these materials were analyzed for oil content and composition. Seed-oil of N-10 has high iodine value while that of the other line has low iodine value.

It was found that the iodine value of safflower oil: (a) is determined by the genotype of the seed and not by that of the sporophyte on which the seed develops; (b) is not influenced by maternal effects; (c) is controlled by a single locus with one recessive allele producing low iodine value and the other, partially dominant, producing high iodine value; and (d) has a very high heritability.

The oil content of the seed is controlled by several genes without any apparent dominance gene action. Significant positive correlations were found: between (a) iodine value and palmitic, stearic and linoleic acid; and (b) between oil content and palmitic acid, linoleic acid, and iodine value. Significant negative correlations were found between oleic acid and palmitic acid, linoleic acid, iodine value and oil content.

Oil composition was not affected by maternal effects, flower color, spinines

Key Words: seed-oil quality and quantity • iodine value • gas-liquid chromatography • fatty acid analysis • scion-stock interaction
