The promising rice varieties were grown in different agro-ecological regions of Chhattisgarh state to study their adaptability to varying climatic and soil conditions. Yield data collected from Department of Agriculture (CG) of 10 rice varieties at 10 locations during kharif-2011-12 to 2013-14. Result of the combined or pooled ANOVA revealed that varieties, environment and genotype-environment interaction were highly significant. Significant genotypic variance indicated genetic diversity among genotypes yield. Partitioning of the variance component indicated that 12.42 % due to varieties, 65.92 % due to varieties and locations, 18.31 % due to varieties and years, 3.14 % varieties x locations x years and 0.20 % due to error. Further the results of non-parametric stability analysis indicated that the stability value of Swarna (0.01), MTU-1010 (1.33) and IR-36 (1.33) rice varieties were found to be among the most stable varieties for both the methods among all varieties and MTU 1001 (4.66) and PKV-HMT (3.33) were found unstable and ranked tenth and ninth in its stability. Choice of variety for increased grain yield in rice would, therefore, be expected to change yield stability by increasing the values of mean absolute rank difference S (1) and variance S (2) nonparametric stability statistics.
