Abstract :This study was aimed at obtaining information on the effects of G × E interaction on yield among doubled haploid lines insert ignore into journalissuearticles values(DH); of lowland rice and to obtain stable and high yielding lines. The experiment was conducted in 9 environments insert ignore into journalissuearticles values(E);, namely Indramayu insert ignore into journalissuearticles values(2018);, Subang insert ignore into journalissuearticles values(2018);, Malang I insert ignore into journalissuearticles values(2018);, Malang II insert ignore into journalissuearticles values(2019);, Blitar insert ignore into journalissuearticles values(2019);, Cianjur insert ignore into journalissuearticles values(2019);, Lombok insert ignore into journalissuearticles values(2019);, Bali insert ignore into journalissuearticles values(2019);, and Madiun insert ignore into journalissuearticles values(2019);. A randomized complete block design with 3 replications was used in each location. The genotypes evaluated were fourteen doubled haploid rice lines and two check varieties namely Ciherang and Inpari 18. The results of the combined analysis of variance indicated significant effects of genotype insert ignore into journalissuearticles values(G);, environment insert ignore into journalissuearticles values(E);, and genotype × environment insert ignore into journalissuearticles values(G × E); interactions on grain yield. G1, G4, G9, G10, G11, G12, G13, and G14 DH lines had higher genotype mean yield than the average. Among those genotypes, the DH line of G9 was classified as high yielding, stable, and widely adapted in all locations based on Francis and Kannenberg, Finlay-Wilkinson, Eberhart-Russell, Kang, and AMMI analyses.
