A thiobarbituric acid‐gas liquid chromatograph combination procedure is described for rapid screening of individual or half‐seeds of flax for α‐linolenic acid (ALA) in the development of an edible oil flax. The thiobarbituric acid test may be used to screen as many as 1000 seeds in a single day. However, the test needs to be complemented by quantitative determination of fatty acids by gas chromatography. The latter technique has been used to analyze half‐seed of flax. The combination has worked extremely well for the isolation of low ALA mutants of flax.
