ABSTRAKKeberhasilan  seleksi  produktivitas  terna  dan  produktivitasasiatikosida yang tinggi ditentukan oleh kriteria seleksi yang sesuai. Adabeberapa metode yang dapat digunakan untuk mencari kriteria seleksi,salah satu diantaranya adalah dengan memanfaatkan analisis lintas (Pathanalysis). Penelitian bertujuan untuk mengetahui pola hubungan antarkomponen pertumbuhan dengan produksi terna dan produksi asiatikosidaberdasarkan nilai korelasi, pengaruh langsung dan tidak langsung, sertanilai heritabilitas pada 16 nomor koleksi plasma nutfah pegagan. Penelitiandilakukan di KP. Cimanggu, Balai Penelitian Tanaman Obat dan Aromatik(BALITTRO) antara bulan Juli-November 2007, dengan menggunakanrancangan acak kelompok (RAK) yang diulang 2 kali. Intensitas cahayayang digunakan 75%. Komponen pertumbuhan yang diamati meliputijumlah, panjang, dan diameter tangkai daun; jumlah, panjang, lebar, luas,dan tebal daun; serta jumlah sulur. Hasil penelitian menunjukkan bahwapeubah panjang dan diameter tangkai daun; serta panjang, lebar, luas, dantebal daun berkorelasi positif sangat nyata terhadap produksi terna.Berdasarkan analisis lintas, panjang, dan diameter tangkai daun, panjang,lebar, luas, dan tebal daun berpengaruh tidak langsung terhadap produksiterna melalui peubah lainnya. Seleksi terhadap produksi terna secara tidaklangsung dapat dilakukan melalui seleksi panjang dan diameter tangkaidaun, dan panjang, lebar, luas, serta tebal daun. Seleksi genotipe pegagandengan produksi terna yang tinggi melalui panjang dan diameter tangkaidaun; dan panjang, lebar; serta luas daun lebih efektif dibandingkandengan melalui tebal daun karena kelima peubah tersebut mempunyai nilaiheritabilitas yang tinggi. Panjang tangkai daun, luas dan tebal daun, sertajumlah sulur mempunyai korelasi positif nyata dan sangat nyata denganproduksi asiatikosida. Luas daun dan jumlah sulur berpengaruh tidaklangsung terhadap produksi asiatikosida melalui peubah lainnya. Panjangtangkai daun dan tebal daun secara langsung berperan dalam menentukanproduksi asiatikosida. Seleksi produktivitas asiatikosida yang tinggimelalui peubah panjang tangkai daun akan memberikan respon yang lebihcepat karena memiliki nilai heritabilitas yang tinggi.Kata kunci: Centella asiatica (L.)

Urban)Selection of asiatic pennywort for high fresh shoot and asiaticosideproduction is determined by using appropriate selection criterion. Thereare several methods that can be applied, one among those is using the pathanalysis. The research was aimed to study the correlation analysis betweengrowth and production variables, direct and indirect effects, and theheritability of sixteen accessions. The experiment was conducted atCimanggu Experimental Station of Indonesian Medicinal and AromaticCrops Research Institute (ISMECRI) Bogor, Indonesia from July untilNovember 2007. The research was arranged using randomized completeblock design (RCBD) with two replications. Sixteen accessions and 75%light intensity were used. The growth components observed were number,length, and diameter of leaf petiole; number, length, width, area, andthickness of leaf; and number of stolon. The results showed that leafpetiole length and diameter, leaf length, width, area, and thicknesspositively and significantly correlated with fresh shoot production. Theleaf petiole length and diameter, leaf length, width, area, and thicknessindirectly affected fresh shoot production through other variables. The leafpetiole length and diameter; leaf length, width, area, and thickness couldbe indirectly selected as fresh shoot production variables. Selection ofasiatic pennywort genotype with high fresh shoot production through leafpetiole length and diameter; leaf length, width, and area were moreeffective compared to through leaf thickness, because the five variableshave high heritability values. Correlations between leaf petiole length, leafarea and thickness, and number of stolon with asiaticoside production werepositive and significant. The leaf area and number of stolon indirectlyaffected asiaticoside production through other variables. The length andthe thickness of leaf directly influenced the asiaticoside production. Leafpetiole length, which has high heritability value, can be used as variable toselect high asiaticoside production of asiatic pennywort.Key words : Centella asiatica (L.)

Abstract

Cashew is a perennial plant so that its breeding cycle requires a relatively long time. One alternative that can be done to accelerate the investigation of superior varieties is the observation method on the existing populations which have expressed their potential genetics and has a preference for the local farmers community. The observation method are directed to investigate the superior varieties for specific location where the selection process involving the local farmers community. This method are identical to the model of Participatory Plant Breeding (PTP) that are oriented to the multilevel user needs (industrial and end user). In order to increase the efficiency and effectivity of the observation methods are recommended  : (1) to increase the empowerment of local farmers communities, (2) to provide the adequate confidence from the government and or plant breeders to the farmers beginning from planning stage until characters selection stage, and (3) to add the location of BPT with their distribution in more specific location based on differences in the biophysical environment, agronomic and socio-economic of local farmers community.
