“…More recently, artificial pollination and hybridization among selected tea types or with wild relatives have become an important breeding strategy for modern tea cultivar development (Wachira et al, 1997 ; Sharma et al, 2010 ). To date, over 5,100 accessions of tea germplasm have been selected and conserved in China and India (Chen et al, 2007 ; Das et al, 2012 ; Yao and Chen, 2012 ) and all genetic stocks for most tea growing countries were directly or indirectly introduced from either China or India (Meegahakumbura et al, 2016 ), although some secondary exchange may have occurred between tea producing nations (Gunasekare, 2012 ; Sriyadi et al, 2012 ; Wambulwa et al, 2017 ). Unfortunately, the breeding history of tea germplasm and the extent of exchange of tea genetic resources between China and India remains poorly understood.…”

Although China and India are the two largest tea-producing countries, the domestication origin and breeding history of the tea plant in these two countries remain unclear. Our previous study suggested that the tea plant includes three distinct lineages (China type tea, Chinese Assam type tea and Indian Assam type tea), which were independently domesticated in China and India, respectively. To determine the origin and historical timeline of tea domestication in these two countries we used a combination of 23 nSSRs (402 samples) and three cpDNA regions (101 samples) to genotype domesticated tea plants and its wild relative. Based on a combination of demographic modeling, NewHybrids and Neighbour joining tree analyses, three independent domestication centers were found. In addition, two origins of Chinese Assam type tea were detected: Southern and Western Yunnan of China. Results from demographic modeling suggested that China type tea and Assam type tea first diverged 22,000 year ago during the last glacial maximum and subsequently split into the Chinese Assam type tea and Indian Assam type tea lineages 2770 year ago, corresponding well with the early record of tea usage in Yunnan, China. Furthermore, we found that the three tea types underwent different breeding histories where hybridization appears to have been the most important approach for tea cultivar breeding and improvements: a high proportion of the hybrid lineages were found to be F 2 and BCs. Collectively, our results underscore the necessity for the conservation of Chinese Assam type tea germplasm and landraces as a valuable resource for future tea breeding.

“…The Bangladesh Tea Research Institute has released 17 cultivars and 6 of them were developed by controlled hybridization (Khan 2012). Sriyadi et al (2012) reported that all 11 GMB (Gambung) series cultivars released in Indonesia were generated from controlled hybridization of first-generation cultivars.…”

“…Kandungan antioksidan teh Indonesia terutamanya Katekin pada klon unggul teh Seri Gambung (GMB) yang banyak digunakan di perkebunan-perkebunan teh Indonesia berkisar 13.9 -17.1% berat kering (Sriyadi et al, 2012). Kandungan katekin tersebut tergolong sangat tinggi, bahkan klon-klon unggul teh Seri GMB (GMB 1-11) tersebut karena kandungan katekinnya yang sangat tinggi, telah menerima penghargaan Idea Award 2009 dari The International Society of Atioxidant in Health and Nutrition…”

European markets have implemented the Commission Regulation (EU) Number 1146/2014 of 23 October 2014 of the MRL for Anthraquinone (9,10-AQ) is 0.02 ppm. After this implementation for 9,10-AQ for tea in the European market, there has been a decreased by 33.6% in Indonesian tea exports. This paper will explain the preliminary study results of 9,10-AQ in Indonesian tea that consist of (1) the results of 9.10- AQ content of Indonesian tea samples, (2) 9,10-AQ content on fresh tea shoot and in each stage of tea processing, (3) the content of 9.10-AQ in tea liquor, and (4) results of antioxidant activity analysis of Indonesian tea in free radical scavenging by DPPH analysis (1,1-diphenyl-2-picrylhidrazyl). Samples selection selected from West Java and East Java as center of tea producing province in Indonesia with incidence of high 9,10-AQ levels in tea. The results show that the 9,10-AQ content depend on drying system technologies. The data conclude that 9,10-AQ level increase due to withering process by 0.004 ppm and in drying process it increase higher (0.007 ppm). The data of 9,10-AQ level of tea liquor are all below the MRL, therefore brewed tea is safe for health. Antioxidant activity of Indonesian tea with 9,10-AQ level above the MRL (0.043 ppm) is very strong that very potential to reduce the negative effects of tea contaminants by free radicals scavenging.
