Abstract :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 insert ignore into journalissuearticles values(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 insert ignore into journalissuearticles values(L);, genotype insert ignore into journalissuearticles values(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 insert ignore into journalissuearticles values(V17);, Khaokam Gs.no. 88084 insert ignore into journalissuearticles values(V5); and KKU-GL-BL-11-001 insert ignore into journalissuearticles values(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 insert ignore into journalissuearticles values(V25); and KKU-GL-BL-06-043 insert ignore into journalissuearticles values(V23);. The desirable genotypes for gamma oryzanol yield were KKU-GL-BL-11-001 insert ignore into journalissuearticles values(V25);, Niewdam Gs.no. 21427 insert ignore into journalissuearticles values(V3); and KKU-GL-BL-06-043 insert ignore into journalissuearticles values(V23);.
