In total 28 accessions of Jesso-balam rice were characterized for 38 morpho-physicochemical characters at Bangladesh Rise Research Institute during T. Aman 2009 and 2011 seasons. The analysis of variance showed highly significant differences (p<0.01) among the genotypes for all the characters. The mean separations showed high degree of variations and no single duplicate was found. The culm height (cm) ranged from 99.74 (JB20)-138.53 (JB22), effective tiller number per hill from 7 (JB6)-15 (JB4, JB26), strawyield per hill (g) from 21.01 (JB26)-47.01 (JB22), panicle length (cm) from 23.49 (JB20)-29.89 (JB22), primary branch number from 9.67 (JB20)-13.67 (JB23), secondary branch number from 19.67 (JB20)-53 (JB18), grain length (mm) from 5.92 (JB26)-9.37 (JB8), 1000-grain weight (g) from 11.0 (JB26)-25.88 (JB14), protein content (%) from 5.9 (JB15)-9.9 (JB26), grain yield per panicle (g) from 1.65 (JB12)-3.37 (JB21) and grain yield per hill (g)from 16.67 (JB26)-26.4 (JB4), respectively. The high GCVand h super( 2) sub( b) together with high GAPM were found in 1000-grain weight, seedling height, secondary branch number, panicle exertion, effective tiller number per hill, strawyield per hill and penultimate leaf area suggested that selection may be effective for these characters in segregating generations. The simple correlation indicated that the higher the PBN, SBN, SBFGW, LBR and TGW possessed greater PL, GL and PGY. Finally, the pure lines of Jesso-balam rice germplasm offers valuable gene reservoir which need to conserve and characterize using molecular tools for validating useful genes.
