Variations in Fruit and Seed Characteristics of Wild Tea Populations in Jeollado

This study was conducted to investigate variations in fruit and seed characteristics among populations and individuals within populations of wild tea (Camellia sinensis L.) distributed in Jeollado. Twenty fruits were collected from 10 populations, and nine characteristics of fruits and seeds were analyzed. ANOVA analysis showed significant differences among populations and individuals within populations in terms of fruit and seed characteristics. According to nested analysis, variance contributions among individuals within populations were higher than those among populations. Therefore, for ex situ genetic conservation of C. sinensis, individual selection was recommended over population selection. Cluster analysis using an average linkage method showed three groups at a Euclidean distance of 0.99. However, there was no significant relationship between population association and geographical distribution. Some morphological characteristics such as fruit width (0.060), seed width (0.026), and seed length (0.019) showed relatively high differences in values of differentiation (Dij) among populations. Of the 10 populations, Sungsan (0.038) was highly differentiated based on the total mean Dij of nine morphological characteristics, whereas Unheungsa (0.006) were scarcely differentiated.
