Abstract: Rice is the major cereal crop of India. Aromatic rice possesses immense diversified quality of size, shape and appearance of grain, milling quality and cooking properties (Dela Cruz and Khush, 2000). Most of the varieties are small and medium grained under aromatic rice, possessing excellent aroma and other quality traits like elongation after cooking, taste, flavour etc. In the present scenario, when govt. is focusing to double the farm income by 2020. Rice can be a turning point for income enhancement. In this backdrop, aromatic rice of short grain feature is a boon for farmers for profit making. It is grown in pockets of provinces like Bihar, Orrisa, Madhya Pradesh, Chhattisgarh, Uttar pradesh etc. (Singh et al.,). The present study was carried out on aromatic short grain rice genotypes tested under Advance Varietal Trial-Two (AVT-2) consisting of total 11 entries along with three checks {(Kalanamak (RC), Vishnubhog(LC) & Badshahbhog(NC)} to screen out the best genotypes compared to checks and to advance such entries for next level. Along with the screening a study on genetic parameter has been conducted to advance the genotype on the basis of sound genetic principles. The trial was conducted at Barrister Thakur Chhedilal College of Agriculture and Research Station, Sarkanda (IGKV Raipur), Bilaspur, Chhattisgarh during kharif 2013-14. Analysis of variance reflected significant differences among the genotypes for all the traits studied. The CD value of (5.99) confirms that genotypes numbered PNR 546 (48.22 q/ha) and CN 1646-6-11-9 (47.78 q/ha) out yielded all the three checks viz. Kalanamak (32.44 q/ha), Vishnubhog (28.67 q/ha) and Badshahbhog (20.00 q/ha). The phenotype variance was higher in magnitude than that of genotypic variance for all studied characters indicates the influence of environmental factors on these traits. The estimates of genotypic & phenotypic coefficients of variation (GCV & PCV) were high for all the characters (flowering, plant height, panicle length, flag leaf length, tillers pet plant,1000 grain weight and grain yield) except days to maturity. Heritability in broad sense was highest for all the characters. High heritability along with high genetic advance as percent of mean was registered for grain yield, 1000 grain weight, tillers per plant, flag leaf length, panicle length & plant height. Its indicates the involvement of additive type of gene action in controlling these character & selection will be effective for crop improvement.
