Fig. 1. Pedigree and oleic acid concentration in S0, S1, S2, and S3 generations of a variant castor plant of PI 179729: a) fixation of ‘OLE-1’ mutant through the S1 plant Or80-3; b) fixation of ‘OLE-1’ mutant through the S1 plant Or80-6; c) fixation of ‘OLE-1’ mutant through the S1 plant Or80-13. In S0 generation, bulk seed samples were analyzed. In S1, S2, and S3, half-seeds were analyzed.
