Abstract: Identification of scented fine slender rice varieties with wider adaptability and stability are the important aspects in varietal recommendation to achieve better economic benefits for farmers. Multi location trails are conducted in different locations / seasons to test and identify the consistently performing varieties of wider environments and location specific high performing varieties. So, the present field experiment with thirty four scented fine slender rice genotypes including checks was conducted at Raipur, Jagdalpur, Kawardha and Raigarh research stations of Chhattisgarh during the Kharif 2015 to screen out the rice genotypes with wider adaptability and stability. The stability analysis revealed that genotype, environment and genotype (G) x environment (E) interaction were significant for all the characters except for 1000 grain weight. The pooled analysis of variance in stability showed significant differences between the genotypes for all the characters. In the present study based on stability parameters and over all mean, genotype R 1656-2151-1-412-1 was found stable for all environments in performance for grain yield, because this entry had high mean, unit regression and non-significant deviation from regression for grain yield, Whereas entry R 1926-1013-2-595-1 and R 1747-4941-1-515-1 had regression value below than one (bi < 1) and deviation from regression was non-significant, so these entries were found to be suited for unfavorable / poor environments.
