The characters under study were divided into two sets as Set-I and Set-II, where, Set-I comprised of 7 morphological characters and Set-II comprised of 7 quality characters. Characterization of aromatic rice accessions was undertaken in form of written evidence for the traditional rice germplasm of Chhattisgarh. The mean for panicle length was 22.24 cm, for fertile spikelets per panicle the mean was 103.29, for brown rice length, the mean was observed to be 5.62 mm, for head rice recovery percentage the mean was observed to be 54.01 per cent, similarly for grain yield per plant the mean was 10.14 g and for brown rice elongation ratio the mean was 1.53. The range for panicle length varied from a minimum of 12.05 cm to a maximum of 30.85 cm, similarly, for fertile spikelets per panicle it varied from 21 to 237.50, for brown rice length it varied from 3.97 mm to 7.68 mm, for brown rice elongation ratio it varied from 1.26 to 2.04, for head rice recovery it varied from 27.49 per cent to 74.18 per cent. Similarly, for grain yield per plant the value ranged from a minimum of 4.61 g to 15.50 g. Results of the analysis of variance indicated that the mean sum of squares due to genotypes were highly significant for all the characters.. Highest heritability was observed for amylose content and brown rice L/B ratio. High heritability was observed for almost all characters like fertile spikelels per panicle, spikelet sterility percentage, 1000-grain weight, rough rice length in Set - I. The ear bearing tillers per plant and panicle length had moderate heritability. In Set-II high heritability was observed for the characters such as brown rice length, brown rice breadth, brown rice elongation ratio, amylose content, alkali spreading value, head rice recovery percentage. The D2 analysis indicated the presence of appreciable genetic diversity in the material. The 144 genotypes were grouped in two sets as Set-I and Set-II, each having eight clusters. The genotypes Dubraj, Badshahbhog, Vishnubhog, Kalajira, Rajim-14, Dumarphool etc. were selected, on the basis of cluster analysis, for the improvement of both, morphological and quality characters. In Set-I, comprising of morphological characters, grain yield per plant showed positive and significant correlation with panicle length. In Set-II, comprising of quality characters, head rice recovery showed positive and significant association with elongation ratio. The genotypes having high degree of grain elongation S intermediate gelatinization temperature and narrow L:B ratio would be effective criterion for improvement of quality aspects.enThesis
