The inheritance of increased (mid) oleic acid content about 62% of an inbred line, LG27, was studied in the crosses with high oleic HA89OL (89%), high oleic LG26OL (86%) and low oleic LG28 (22%). Fatty acid composition of single seeds was determined by gas chromatography of methyl esters. The crosses of high x increased oleic and high x low oleic genotypes revealed the genetic control on oleic acid content with multiple allelism. Three alleles of one gene - dominant Ol, recessive ol(1) and recessive ol lead in homozygote to the high, increased and low oleic phenotypes, respectively. Genetic segregations in F2 and BC of the cross of increased x low oleic lines did not show clear-cut phenotypic classes. No maternal inheritance was observed.
