  • Descrição: Abstract The identification of local rice germplasms resources is essential for determining morphological and anatomical traits for agronomic applications. In this study, we have screened several local rice germplasms from Aceh, conducted in Gampong Paloh Lada and Agroecotechnology Laboratory, Agriculture Faculty, Universitas Malikussaleh, Aceh Utara Regency, from February to June 2023. The study employed Randomized Block Design Non-Factorial, consisting of 7 lines of local germplasms, including Unsyiah Cakep, Unsyiah Seumeulu, Cot Bada, Sigunca, Sigupai, Cot Bada and Rajasa (control). Flowering age, net assimilation rate, relative growth rate, root length, shoot – root ratio and 1000- grain weight was observed. The results of this study showed that there were significant differences between several rice strains on the variables of flowering age, net assimilation rate 40-20 DAP, relative growth rate 60-40, shoot-root-ratio at 60 DAP and harvest, root length, 1000 seed weight. Cotbada eight and Cotbada four strains gave the best effect compared to Rajasa (control) and other strains, seen in the parameters of relative growth rate two, number of grains per clump, weight of 1000 seeds and yield tonnes/ha. Cotbada four strain with a production of 7.24 tonnes/ha and followed by Cotbada eight strain with a yield of 6.48 tonnes/ha.
