Study on Green Tea Leaf’s Quality and Quantity by Testing Varieties Selected and Breeded in South Gyeongsang Province

The aim of this study was to investigate the quality and quantity of three varieties of green tea leaf, Gyeongnam 1, 2, and 3. The results are summarized as follows. Bud length of the tested varieties were longer than Charmrock [Yabukita > Gyeongnam 2 (GN 2) > Gyeongnam 1, 3 (GN 1. 3) > Charmrock]. Leaf width, leaf length, and leaf area of GN 2 were similar to Charmrock and Yabukita. Ratio of bud emergence for GN 2 was higher compared to Charmrock and Yabukita. The moisture level of GN 2 was less than Charmrock and Yabukita, but the amount of crude protein was higher. For mineral elements, the amount of Na, Fe, and Mn in GN 1, 2, and 3 was significantly higher than in Charmrock and Yabukita. The levels of tannin and polyphenols in GN 1, 2,3 were lower compared to Yabukita and Charmrock, but the amount of GABA was higher.
