Camellia sinensis
(L.) O. Kuntze] is one of the top non-alcoholic beverages consumed around the world; its genetic and phenotypic diversity is less understood compared to other plantation crops. The study’s aims were to undertake phenotypic and genotypic characterization of Sri Lankan and Indian tea germplasm and to identify diverse accessions to accelerate tea breeding programmes in both countries. A total of 171 tea accessions, comprising 94 Sri Lankan and 77 Indian accessions were used. All the accessions were subjected to phenotyping and genotyping using 28 polymorphic simple sequence repeat (SSR) markers. Based on 16 morphological characters, the first three principal components explained 57.61% and 58.43% of the total variability of Sri Lankan and Indian accessions, respectively. Young shoot pubescence, young shoot pigmentation, serration of leaf margin, and mature leaf colour contributed positively to the grouping of accessions. Based on Neighbor-joining analysis, all Sri Lankan accessions grouped in a single cluster, whereas Indian accessions grouped in two distinct clusters. The Gower’s distance method was the most appropriate than other methods for developing core subsets. Among 21 Sri Lankan core accessions selected, 11 accessions belong to introductions, five TRI-developed cultivars and five estate selections. Among 18 Indian core accessions selected, 11 belong to China types, two Assam types and five Indian recommended cultivars. The current study is the first study to compare tea germplasm of both countries and the results are useful for tea crop improvement programme, conservation and utilization of tea germplasm in India and Sri Lanka in the future. |
