Catechin content in tea plant is a major character in tea breeding program for a healthy beverage. A tea breeding program for high catechin content maybe will performed by indirect selecting a trait or traits that signiÂficantly correlated with high catechin content. This research was performed to identify morÂphological traits which maybe significantly correlated with high catechin content in tea plant. A randomized complete block design with three replications was used in this experiment using 10 selected clones. The experiment was performed in Gambung Experimental Station ot the Research Institute for Tea and Cinchona, Gambung, West Java. Catechin content, triÂchoma density of young leaves, weight of p+2, size of mother leaves, chlorophyll content of mother leaf, stomatal density of mother leaf, mother leaf thickness, and mother leaf angle, were measured. The results indicated that stomatal density and mother leaf angle were significantly correlated. Based on path analysis indirect selection for high catechin content could be performed by selecting stomatal density considering to trichoma density, mother leaf angle and chlorophyll content. In addition, indirect selection for high catechin content could be performed by selecting other leaf angle independently without considering other morphological traits.

Efforts to improve the productivity of tea needed new high yielding clones were obtained from the cross and easily propagated vegetatively. Preliminary testing of the clonesÂ needs to be done to determine the growth of cuttings and rooting properties of tea clones from hybridization which are selected by potential production. This study used a Randomized Complate Block Design with three replications. The treatments consist of 14 clones from crosses and GMB 7 as clone comparison. The data is analyzed by using ANOVA and Scott Knott test with the level of 5%. The observations are intended to look at the growth of roots and shoots by dismantling seedling in polybag predetermined randomly at each observation. The results showed that the clones tested had good growth with a low mortality rate, and easily propagated vegetatively. The S / R ratio also showed shoot growth more faster than the growth of root. This character is advantageous because the most appropriate selection criteria for planting in the field.

Vegetative propagation is common system that carried out in tea propagation. Seedling propagation was not reliable due to time consuming and phenotypic variability in seed plant. Despite yield potential, good quality, pest and disease resistant characters, the easy of vegetative propagation is very important character in tea breeding process. The aim of this study is to selected clones that resulted by artificial pollination for an ability of vegetative propagation character. Plant materials that tested in this experiment were the seed from the vegetative propagation of 14 clones, and GMB 7 clone as a control. Randomized Block Design was used in this experiment by 3 replications. The data analysis was ANOVA and Scott Knott test. The result of the experiment showed that clone number 41, 45, 38, 149, X5, X3, 122, 78, and 44, were the easiest clones to be vegetative propagated.

One factor affecting the quality of tea is the selection of plant material that would be planted on the field. Clonal selection is a common way to produce tea with better quality. However, as a natural cross pollination species, tea often consists of various clones or progenies of cross-pollinated process. This commonly occurs on plantations owned by smallholder farmers. To produce a consistent quality tea, the clones or progenies need to be identified. Usually, human experts distinguish the plants from leaves by visual inspection on the physical attributes of the leaves, such as the textures, the bone structures, and the colors. It is very difficult for non-experts or common farmers to do such identifications. In this, we propose a deep learning-based identification of tea clones. We apply deep convolutional neural network (CNN) to identify 3 types of tea clones of Gambung series, a series of tea clones developed at Research Institute of Tea and Cinchona. Our study indicates that the performance of the CNN systems are affected by the depth of the convolutional layers. VGGNet, a popular CNN architectures with 16 layers, achieves better accuracy compared to AlexNet, a CNN with 6 layers.

Background: Increased lipase activity can increase the amount of monoglycerides and fatty acids absorbed by the body, this is what affects obesity. If pancreatic lipase activity is inhibited, the production of fatty acids will decrease, consequently the level of fat in the blood will also decrease.Objective: To study anti obesity potential of a single herb or a mixture of green tea and other herbs (Syzygium polyanthum. Lv, Artocarpus communis.Lv, Cinnamomum verum..Lv, Manilkara zapota.Lv, Tectona grandis.Lv) by the in vitro inhibition assay of the lipase enzyme activityMethod: A single (8 herbs) or a mixture of three herbs powder (12 formulas) was put into a tea bag with a total weight of 1.5 g to be brewed in 100 mL bottled mineral water at 70â°-90â°C for 10 minutes. In vitro lipase enzyme inhibition assay were conducted to measure the ability of these samples as lipase inhibitor. Orlistat used as positive lipase inhibitor. Results: There was a difference results of lipase inhibition activity between the sample of a single and a mixture of herbs. Interestingly, the results shows that formula 3 (mixture of green tea, Manilkara zapota and cinnamon). has 53.942 % inhibition, formula 9 (a mixture of green tea, Syzygium polyanthum and cinnamon) has 67.322 % inhibition and formula 12 (a mixture of green tea, Tectona grandis and cinnamon) has 56.612 % inhibition which close to lipase inhibitory activity by standard Orlistat.Conclusion: The mixture of green tea and two other herbs has a lipase inhibitory activity similar to Orlistat, when compared to the single herb. The highest lipase inhibitory activity is found in formula 9.
