Grain yield was influenced by genotype, environment and, genotype x environment interaction, so the maximum potential of rice will appear when planted in a suitable environment. The study aims to estimate grain yield stability of 20 genotypes of rice in dry season of 2014 in three locations. The experimental design used was a randomized complete block design with three replications. The average grain yield of the three locations ranged from 5.60 to 7.89 ton/ha. Based on the combined analysis of variance, the interaction between the genotype x environment was significant. Six lines have grain yield were not significantly different fromCiherang, which were BP5168F-KN-16-3, BP4114-7f-Kn-22-2-KLT-2*B-SKI- 1*B, BP5168f-kn-16-3-KLT-2*B-SKI-1*B, BP11282f-Kn-4-3-KLT-2*B, BP5478-1f-Kn-19-1-2-KLT-2*B-SKI-1*B, and HHZ12-SAL2-Y3-Y1. Only OBS 8412 which has grain yield higher than Ciherang. Based on the coefficient of regression and coefficient of variability, HHZ12-SAL2-Y3-Y1 and OBS 8412 were stable and have general adaptability in Cilacap, Sukabumi, and Kebumen. BP12244-20-3-1-3 and HHZ12-SAL8-Y1-Y2 were specifically adapted in the low yielding environment. BP5480-3f-Kn-4-1-KLT-2*B, Ciherang, and INPARI 32 HDB were specifically adapted in high yielding environment.
