Abstract

Southeast Sulawesi, which is located in the southeastern part of the island of Sulawesi, is one of the upland rice producers in Indonesia. Upland rice cultivation in Southeast Sulawesi is still not optimal because the community is still focused on developing lowland rice. Southeast Sulawesi has extensive dry land area and local upland rice genotypes have good growth and yield potential. This study aimed to determine the differences in the growth of several local upland rice genotypes of Southeast Sulawesi which were cultivated in Kendari City. This research was carried out in Experiment Field 2, Faculty of Agriculture, Halu Oleo University, which is located in Kambu District, Kendari City, Southeast Sulawesi. The research was conducted using a randomized block design (RBD) consisting of 10 genotypes, namely Wagamba (V1), Wangkariri (V2), Momea (V3), Waburi-buri (V4), Konkep (V5), Bakala (V6), Wakawondu (V7), Tinangge (V8), Loiyo putih (V9) and Bombana (V10). Each treatment was repeated 3 times in order to obtain 30 experimental units. The results showed that potential genotypes that can be developed in Kendari City were Wakawondu genotype based on parameters of the number of tillers, plant height, and number of leaves, Wagamba genotype based on leaf width parameter, and Wangkariri genotype based on the flowering age and number of tiller parameters.
