To meet the growing demand of rice crops, most of the researchers are focused on producing high yielding varieties without considering the potential grain quality attributes of landraces. So, to excavate the knowledge on grain quality study was carried out with twenty landraces of rice (Oryza sativa) found in Tanahun, Lamjung and Kaski districts of Nepal for the assessment of physical, Physico-chemical and cooking traits in Complete Randomized Design at the research laboratory of Lamjung Campus. All 20 varieties were examined for physical traits such as hulling, milling percentage, bulk density, 1000 kernel weight and grain dimensions, landraces were found to be significantly different at (p>0.05). Ekle was found to have the highest bulk density and 1000 kernel weight of (0.90±0.009 g/cm3), (26.25±0.41 g) respectively. Among the studied landraces 60% of the landraces were found to have high gelatinization and 40% of the landraces were found to have intermediate gelatinization temperature. The longest gel length and elongation ratio were recorded in Tude (85.67±2.33 mm) and Tilki (1.55±0.02 mm) respectively. Landraces such as Ekle, Tude, and Kalogede are on the verge of being obsolete, yet they are found to be noble in terms of physico-chemical and cooking traits so these landraces can also be used in modern rice breeding programs.
