(Tanjung Raja, Indralaya, Jejawi, SP Padang, and Kayuagung). All materials were tested using Randomized Block Design Complete with four replications. Each plot size 5 m × 5 m, number of seeds/holes 2–3 rod, a spacing of 25 cm × 25 cm. The characterization was done based on Rice Characterization and Evaluation Guide of the National Commission for Rice Germplasm. Morphological characters were presented in qualitative data and analyzed by mode (Mo) analysis, while the agronomic characters were showed on quantitative data and analyzed by analysis of variance (ANOVA). The observation and analysis were indicated that the five local rice Pegagan (Siputih) which collected from 5 different district were showed no diversity, both on morphology and agronomic characters. Purity analysis by roughing showed 0.15% mixed with others varieties and 1.85% plant have the deviation characters. The result of variety purification activity was obtained 98% pure.
