To understand genetic diversity in nutritional properties, 157 accessions of Korean-bred rice varieties were cultivated in 3 separate fields and harvested brown rice were used for determination of tocopherols (T), tocotrienols (T3), squalene (SQ), campesterol (CA), sitosterol (SI), and stigmasterol (ST) contents as well as fatty acid compositions. The average contents of α-T, γ-T, α-T3, γ-T3, SQ, CA, SI, and ST were 11.9, 1.6, 10.0, 13.9, 35.2, 42.1, 163.5, and 20.0 μg/g, respectively, and total tocols, SQ, and total phytosterols contents ranged 26.8-54.9, 7.9-78.4, and 162.9-320.2 μg/g, respectively. Ecotype of rice significantly affected phytonutrient contents in that japonica-type showed significantly higher α-T and α-T3 contents and α-T/γ-T, α-T3/γ-T3, and T/T3 ratios compared to indica-type varieties. Total T, SQ and ST contents were also higher in japonica-types, while total T3, CA and SI contents were not affected by ecotypes. Linoleic, oleic, and stearic acids were the 3 major fatty acids consisting 36.5, 35.8, and 22.9% of total fatty acids, respectively. Positive correlationships were observed among 3 phytosterols, while oleic acid showed negative correlation with palmitic (

The
objective
of this study was to analyze fruit qualities (i.e., pH, soluble solids content, titratable acidity, and mineral content) as well as fatty acid and phenolic compounds (i.e., ellagic acid and anthocyanins) among hybrid boysenberry lines developed by hybridization and gamma irradiation. There were no significant differences in the hybrid boysenberry fruit pH and titratable acidity (%) among the tested genotypes. However, the soluble solids content was higher in the BSA119 and BSA144 mutants than in the original genotype (BS_Hybrid). Meanwhile, linoleic acid was the most abundant fatty acid in the analyzed hybrid boysenberry fruits. The fatty acid composition did not differ significantly among the genotypes. The ellagic acid content of all genotypes ranged from 8.72 mg/100 g to 46.10 mg/100 g, with the highest concentration observed for the BSB127 genotype. Additionally, cyanidin-3-
