Characterization of genetic resources will provide added value in enriching gene diversity. As many as 24 local rice genotypes have been found in Kuantan Singingi Regency. However, the specific problem of this study is that the level of diversity and kinship is unknown. This study aims to determine the level of kinship and diversity of 24 local rice genotypes from the Kuantan Singingi Regency. This study used an experimental method in which to assess the level of diversity and kinship, planting and observation (identification) of the characteristics of rice plant organs had to be carried out using the International Rice Research Institute (IRRI) translated edition of the Standard Evaluation System (SES) guide in 2003. Observational data, then processed using Ms. software. Excel and (NTSYS-pc) version 2.11 to get a kinship tree or dendrogram. The results showed that the criteria for wide and narrow levels of diversity. At the same time, the degree of kinship ranges from 0.49-0.90. Only the PL17 (pulut benai rice from Kinali Village) and PL22 (gondok rice from Market Inuman Village) genotypes had a high consanguinity coefficient of 0.90 (90%). The degree of consanguinity of other genotypes is low. The lower the level of kinship, the potential to be used for developing rice plant breeding in the future. Further research is hoped to identify the resistance properties of 24 local rice genotypes from Kuantan Singingi Regency to biotic and abiotic stresses.
