Interpretive Summary:

Technical Abstract: Seeds from eight sesame (Sesamum indicum L.) genotypes may vary for seed protein, sesamin, and sesamolin content for potential use as a functional health food worldwide. The lignans, sesamin and sesamolin found in sesame oil have been reported to have anti-cancer activities. The objectives of this study were to evaluate protein, sesamin, and sesamolin in seeds from 8 sesame genotypes over two years. Significant genotype and year by genotype interactions were found for protein, but only genotype effects for sesamin and sesamolin. Mean separations revealed significant variability for protein, sesamin, and sesamolin among genotypes. The genotypes, PI 158906 (black seeds) and PI 490025 (white seeds) produced the most protein (mean of 21.7%). The genotypes, PI 490025 and PI 490268 (black seeds) produced the most sesamin (8.98 mg/g) and sesamolin (6.3 mg/g), respectively. Significant correlations were observed between the seed traits. This information will be useful to breeders and other scientists for the development of new sesame cultivars with significantly higher health traits such as protein, sesamin, and sesamolin.
