Description Payo rice is one of the local rice varieties from Kerinci, Jambi Province. It is popular in Jambi due to its texture and good taste qualities. Farmer preferences changing to modern varieties and massive infrastructure development lead to Payo rice extinction. This research was aimed to find out the genetic diversity of Payo rice population-based on morphological markers in Kerinci area. Non-experimental research was conducted to obtain the data by direct survey or in situ characterization. Samples were determined using the proportionate stratified random sampling method. Morphological characters were measured both quantitatively and qualitatively based on IRRI and WARDA guidelines with few modifications. Quantitative data were analyzed using the coefficient of variability, while qualitative data were analyzed using relative diversity index (J). Genetic diversity among individual members of the population was analyzed using cluster analysis and presented in a dendrogram. Results indicated that several morphological characters, which were number of productive tillers, angle of flag leaf, threshability, number of empty grain, color of ligule,  color of auricle,  leaf surface, and color of grain, showed large variability, while others were narrow. Overall, relatively large genetic diversity was observed in Payo rice population in Kerinci area. At least 21 different genotypes were identified in the existing population.
Padi payo merupakan salah satu varietas padi lokal dari Kabupaten Kerinci Provinsi Jambi yang cukup populer disebabkan tekstur dan citarasa yang enak. Eksistensi padi payo semakin lama semakin terancam akibat pembangunan infrastruktur dan beralihnya pilihan petani ke varietas unggul modern. Penelitian ini bertujuan mengetahui diversitas genetik populasi padi payo di Kabupaten Kerinci berdasarkan marka morfologi. Penelitian bersifat non eksperimen, data diperoleh dari hasil survai atau karakterisasi langsung secara in situ. Penentuan sampel dilakukan secara Proportionate Stratified Random Sampling. Karakter yang diobservasi merupakan karakter morfologi yang diukur secara kualitatif dan kuantitatif dengan mengacu pada panduan yang dikeluarkan oleh Bioversity International, IRRI, dan WARDA, dengan sedikit modifikasi. Data yang diukur secara kuantitatif dianalisis dengan menggunakan parameter koefisien keragaman sedangkan data yang diukur secara kualitatif dianalisis dengan parameter indeks diversitas relatif (J). Diversitas genetik antar individu dalam populasi dianalisis dengan menggunakan analisis klaster yang ditampilkan dalam bentuk dendrogram. Hasil menunjukkan bahwa beberapa karakter morfologi yaitu jumlah anakan produktif, sudut daun bendera, kerontokan, jumlah gabah hampa, warna telinga daun, warna leher daun, permukaan daun, dan warna gabah, memperlihatkan variabilitas yang luas hingga sangat luas, sedangkan karakter lainnya sempit dan sangat sempit. Terdapat diversitas genetik yang luas dalam populasi padi payo di Kabupaten Kerinci. Tidak kurang dari 21 genotipe berbeda terdapat dalam populasi padi payo saat ini.
