Gamma oryzanol is an important phytochemical of black glutinous rice as it has positive effects on human health. The objective of this study was to evaluate stability of gamma oryzanol content and grain yield for black glutinous rice genotypes grown under different environments. Twenty-five black glutinous rice genotypes and 2 white glutinous rice genotypes were evaluated during 2011 and 2012 in 8 farmers’ fields of Thailand. The experimental trials were laid out in a randomized complete blocks design (RCBD) with 3 replications. Soil data before growing, weather data during growing season, yield components, grain yield and gamma oryzanol content were recorded. The results indicated that location (L), genotype (G) and G×L interaction were highly significant for number of panicles per hill, number of filled grains per panicle, 1000-grain weight, grain yield, gamma oryzanol per grain weight and gamma oryzanol yield. The GGE biplot analysis indicated that KKU-GL-BL-06-023 (V17), Khaokam Gs.no. 88084 (V5) and KKU-GL-BL-11-001 (V25) had both high mean performance and stability for grain yield. The superior genotypes for gamma oryzanol per grain weight were KKU-GL-BL-11-001 (V25) and KKU-GL-BL-06-043 (V23). The desirable genotypes for gamma oryzanol yield were KKU-GL-BL-11-001 (V25), Niewdam Gs.no. 21427 (V3) and KKU-GL-BL-06-043 (V23).
