Abstract
Twenty five different traditional rice landraces from Dibrugarh district of Assam were characterized. In case of morphological characters, high heritability coupled with high genetic advance was recorded for number of grains per plant and number of panicle per plant. For biochemical parameters, high heritability coupled with high genetic advance was recorded for amylose and fat contents. Correlation coefficient analysis revealed that number of grains per plant, plant height, stem length and panicle length exhibited positive correlation with grain yield per plant. Thus, stem length and numbers of grains per plant can be considered in breeding programme. The landraces were with low to intermediate gelatinization temperature range (55–74 oC) indicating good cooking quality. The study identified Kolajoha, Miatong, Bor Aijung, Ronga Bordhan, Bor Salpona, Dolkochi, and Athabora as promising landraces that could be utilized in the development of high yielding landraces.
