Bangladesh Rice Research Institute (BRRI) have developed many high valued rice varieties and advanced rice genotypes including anti-oxidant properties Cyanidin-3-O-glucoside (C3G), phenolic compounds. This study evaluated the performance and stability of two antioxidant-enriched rice genotypes BR12836-4R-63 (V1) and BR12836-4R-312 (V2), along with two released varieties BRRI dhan34 (V3) and BRRI dhan70 (V4) as checks across ten agro-ecological zones in Bangladesh (Satkhira, Bogura, Cumilla, Feni, Gopalganj, Barisal, Rajshahi, Rangpur, Kushtia, and Gazipur) during the 2023 wet (Aman) season. The study was conducted using randomized complete block design (RCBD) with three replications in all the regions. Yield performance and stability of the genotypes were analyzed using AMMI and GGE biplot models. Significant genotype-environment interactions (GEI) were observed, particularly for grain yield (GY), plant height (PHT), and thousand-grain weight (TGW). The highest grain yield was recorded for V4 (3.6 t ha⁻¹), followed by V2 (3.4 t ha⁻¹) and V1 (3.1 t ha⁻¹), with the lowest yield observed in V3 (2.9 t ha⁻¹). Additionally, V2 exhibited a shorter growth duration (130 days) than the check varieties, suggesting its potential for early-maturity breeding programs. The AMMI analysis revealed that V4 and V2 were the most stable and high-yielding genotypes, whereas V1 and V3 showed poor adaptability. The GGE biplot identified BRRI dhan70 (V4) as the stable and adaptable genotype, while BR12836-4R-312 (V2) demonstrated strong performance in specific environments, particularly in Cumilla, Feni, and Rajshahi. The findings suggest that the advanced line BR12836-4R-312 would be released through national system of Bangladesh as anti-oxidant enriched rice variety.
