The objective of this study was to establish the effective use of spot test for early selection of perilla mutants which have low α-linolenic acid in seed oil. The average α-linolenic acid content with 30 accessions determined by GLC was 57.9% and the contents ranged from 51.4 to 65.6%. The results of spot test, red colour is related to high α-linolenic acid content in perilla whereas yellow colour indicates absence of α-linolenic acid. The colour density by an image analysis was highest in perilla among oil crops tested. The correlation coefficient between colour density by spot test and α-linolenic acid content determined by GLC was highly significant. Therefore, the spot test was considered useful as a preliminary screening method for the relative α-linolenic acid content in mutation breeding.
