As an effort to conserve tea clone accessions of first generation from genetic erosion, arrangement germplasm in one particular block/area to be easily monitored and managed, is needed. Ideally, tea germplasm collection should consist of a few clone accession number but high genetic variability. To select representative clones that will be conserved in new germplasm collection, leaves morphology similarity has been analysed by cluster analysis using average method. The results showed that by using leaves morphology parameter, from 50 tea clone accession of first generation coming from several tea plantations, it could be reduced into 25 clone accessions from seven clusters, which each has high similarity. The first cluster with 60% similarity could reduced accession from 15 to 6 clone. The second with 74,8% similarity from 25 to 13 clones. The third with 74,8% similarity, from 4 to 2 clones. The fourth with 61,3% similarity, and seventh with 82,1% similarity, both could reduce from 2 clones to 1 clone. To design a tea germplasm collection with 50 accessions of genetic variability, it could represented by 25 clones with low similarity, i.e PG 3, KP 1, Skm 18, Cin 69, Cin 67 dan Cin 58 as the first cluster representatives, Mel 101, PG 4, Pam 15, PG 5,Â PG 11, GP 2, BD 13, SA 49, Cin 66, Mal 16, Bks 6 and Sin 5 the second cluster representatives;Â Â Mel 108 and Cin 13 as the third cluster representatives; and Cin 15, Cip 37, GH 5, as well as GP 4 as the fourth, the fifth, and the sixth representatives, respectively.

Assembling of new excellence high yielÂding and good quality tea clones was started from identification accession as gene sources, crossing design of parents, selection mother bushes and propagated vegetatively. Crossing beetwen two parent clones which near or remote genetic relationship in tea will failed. Assessment of genetic relationship clone accession was done using secondary datas from description of first and second tea clone geneÂration which cultivated in Indonesia. Data of yield potentials and main chemical comÂpound of quality among others catechine, gallat cateÂchine, catechine gallo and cafeine were anaÂlysed using biplot and cluster analysis. The results showed that no correllation beetwen main chemical compound of quality and yield potentials. Biplot with two dimensions could be explained 92,5% variation of five characters and showed that yield has the highest and catechine the smallest variances. The first geneÂration of tea clones was separated to second at the 46,79% similarity levels. At the 15,60% similarity levels, there were six clusters. GMB 1, GMB 2, GMB 6, GMB 9, and GMB 10 clones were in one cluster was caused of they had high of yield and catechine. GMB 4 and GMB 5 had similarity on medium yields, GMB 7 and GMB 11 had similarity on medium catechine and the highest yield, and GMB 3 and GMB 8 had similarity on low catechine. PS 1 with the lowest catechine gallo was separated to the others. The sixth cluster were SA 40, Kiara 8, SA 35, RB 3, and Cin 143 were characterized by low catechine and yields.Â

The aim of this research was to obtain the effect of insecticide combination with nitrogen and zinc foliar fertilizers to Empoasca flave-scens. An experiment was conducted at Gam-bung Experimental Garden, Bandung, West Java. The trial was arranged in a randomized complete block design with nine treatments (A)methomyl; (B) methomyl + ZnSO4 1%; (C) me-thomyl + ZnSO4 2%; (D) methomyl + N 1%; (E) methomyl + N 1% + ZnSO4 1%; (F) metho-myl + N 1% + ZnSO4 2%; (G) methomyl + N 2%; (H) methomyl + N 2% + ZnSO4 1%; and (I) methomyl + N 2% + ZnSO4 2%, replicated three times. Each unit consisted of experiments is 40 plants. The treatments comprised: concen-tration of methomyl 0,5 gram/l with sprayed volume 200 l/ha. The level concentrations of nitrogen and zinc were 1% and 2%. The appli-cation of treatments was sprayed six times after plucking with 12 days interval, respectively. The population and intensity of E. flavescens attack were measured at the time of plucking. The effectiveness of treatment on the population as well as attack intensity of Empoasca con-ducted by measuring the rate of decline through a linear regression approach. The results showed that all of the treatments could reduce the population as well as the attack intensity of E. flavescens but there were no significantly different among others and were comparable to the chemical insecticide treatment. The fastest rate of decline were indicated by the treatment methomyl + N 2% + ZnSO4 1% and methomyl + N 2% + ZnSO4 2%.

Cinchona plants commonly propagated through vegetative propagation using grafting between scion and rootstocks and planting on mixed of top soil and sub soil. To overcome these problems, an alternative planting medium of cinchona seedling has to be explored to reÂduce the use of soil. In this research, various organic materials have been tested to see their effect on growth and root formation of cinchona seedling at early stage of cinchona nursery. The experiment was arranged in a randomized complete design (RCD) with 17 treatments, each treatment consists 20 plants/replication. Treatments tested were combination of organic matter (cocopith, rice husk, sawdust and peat soil) with top soil (15% and 25%). Cow dung or seaweed, as organic fertilizer was added to enrich planting medium. Results shows that coÂcopith, rice husk, sawdust and peat soil enÂriched with cow dung or seaweed has no signiÂficance difference with top soil medium (conÂventional planting medium) on plants living percentage, plants height, leaves number and, stem diameter of cinchona seedlings at early stage of cinchona nursery comparing with the conventional way. On plants heights and leaves number, there are significant difference caused by the treatment during three months after plantings. The number of rooting plants in betÂween 33% up to 100%. In general, plants reÂgeneration and compatibility between scion and rootstock of cinchona tested plants shows that the cell regeneration or cell growths are well and there is no sign on incompatibility between scion and rootstock.

The rate of increase tea cost production in several tea fields could not be offered by the rate of increase selling price. The fact that the cost of plucking machine is lower than manual plucking has attracted the interest and attention of tea smallholder to change from manual plucking to plucking machine. The plucking machine which were imported from japan was not designed for assamica tea in Indonesia. In order to improving performance of plucking machine, the plucking machine need to be designed with support from the field and Â appropriate machine. The aim of this trial was to test the performance of the plucking machine type-120 at plucking of assamica tea with 120 cm of spacing between rows. The plucking type used was medium plucking and kept the Kepel leaves (k +0) in the middle of the bushes using plucking method supported by the garden and the appropriate plucking machine type-120. Results obtained from the test were: (1) The using of plucking machine type-120 with medium plucking, kept the Kepel leaves (k +0), and controlled plucking height did not cause a decrease in plant health, production as well as quality of the shoots. (2) Field work capacity of plucking machine was 1.19 ha/day with work efficiency of 58.2%. (3) The ratio of plucking machine was 0.30/ha with fuel ratio of 0.33 litres/ha. The performance output of the plucking machine could be reached 224 kg/plucker as compared to only 24 kg/plucker when done manually.
