The purpose of this study was to select the predominant tea trees with high contents of nitrogen and tannin in the wild tea germplasms collected at Jeonnam province in 1988. The tea germplasms were first grown in the same field, and then analyzed for total nitrogen and tannin contents in 263 and 293 accessions, respectively. No fertilizer or any similar treatment has been applied to the tea trees since they were planted. Ninety-six percent of the analyzed 263 accessions had mainly 3.0-5.0% total nitrogen content. However, Wolchul 1-10, the accessions name, showed the highest total nitrogen content as 6.34percent. On the other hand, the average tannin content was 9.88±3.98% and ranged from 4.29% to 22.64%. The Moodeung group showed the highest tannin content as 12.55±3.4%, while the Boseong group had the lowest tannin as 6.78±2.0%. The tannin content was distributed mainly from 5 to 15%. Among the 293 accessions, 18 accessions had below 5% tannin content and 4 accessions had more than 20%.
