Zanthoxylum schinifolium is an important short-term income species and a useful resource with various physiological activities. In this study, the distribution and characteristics of seed-rich individuals of Z. schinifolium trees were analyzed. Seed-rich individuals were selected from three regions in consideration of seed yield and growth factors. As a result of the leaf shape survey, the length and width of the leaves were shorter in Jeju and longer in Geochang and Hadong compared to the average. There were very large differences in seed production between individuals within the Z. schinifolium group. The amount of seeds was higher in Jeju and Hadong than in Geochang. As a result of analyzing the correlation between the seven morphological characteristics, the overall correlation coefficient was in the range of -0.910 ~ 0.933. Total seed mass (TS) and seed weight (SW) showed a strong positive (+) correlation. As a result of the principal component analysis, it was classified into two categories. The first principal component showed a high correlation in the order of total seed weight and total seed amount, and the second principal component showed a high correlation with seed length and tree height. As a result of comparing seed production for two years, it was found that there was no change in production. As a result of examining seed viability using the TTC method, all of Z. schinifolium seeds showed more than 90% vitality. It is judged that the above results will serve as basic data for the development of a new variety of seed-rich Z. schinifolium trees.
