ABSTRAKPemuliaan tanaman jarak pagar (Jatropha curcas L.) untukmenghasilkan varietas berdaya hasil dan berkadar minyak tinggi perludilakukan. Penggunaan marka molekuler dapat membantu mempercepattercapainya tujuan pemuliaan tanaman jarak pagar. Marka simple sequencerepeat (SSR) merupakan marka ko-dominan yang efektif untuk mendu-kung program pemuliaan tanaman, tetapi penerapannya pada jarak pagarmasih terbatas. Penelitian yang dilakukan bertujuan untuk : (i) merancangprimer spesifik SSR menggunakan aksesi DNA jarak pagar yang tersediadi GenBank DNA database dan (ii) mengevaluasi efektivitas pasanganprimer yang dirancang untuk menghasilkan marka SSR yang polimorfikuntuk jarak pagar dan J. multifida. Dua puluh delapan pasang primerspesifik SSR telah berhasil dirancang menggunakan aksesi DNA asal jarakpagar yang ada di GenBank DNA database. DNA genomik jarak pagar danJ. multifida yang diisolasi dapat digunakan sebagai templat untukamplifikasi PCR. Dari 28 pasang primer yang dikembangkan, semuanyamampu menghasilkan marka SSR dari genom jarak pagar dan hanya 19pasang primer yang menghasilkan marka SSR dari genom J. multifida.Dari 19 pasangan primer spesifik SSR yang dievaluasi mampu dihasilkan44 alel dengan ukuran produk amplifikasi berkisar antara 100-360 bp.Sebanyak 35 alel (79,5%) yang diamati merupakan alel yang polimorfik.Marka SSR yang didapatkan tidak polimorfik intra-aksesi jarak pagar atauintra-aksesi J. multifida tetapi polimorfik untuk inter-aksesi kedua spesies.Karena marka SSR yang dihasilkan bersifat polimorfik untuk aksesi jarakpagar dengan aksesi J. multifida maka dapat digunakan sebagai markauntuk mendeteksi hasil persilangan F 1 inter-spesies J. curcas x J. multifida.Kata kunci : Jatropha curcas L., jarak pagar, J. multifida, DNA berulang,rancangan primerABSTRACTDevelopment of Simple Sequence Repeat Markers forJatropha spp.Breeding of physic nut (Jatropha curcas L.) to obtain new varietiesthat are high in yield and oil content needs to be conducted. Molecularmarker could be used to assist breeding of physic nut (J. curcas). Simplesequence repeat (SSR) marker is a co-dominant marker and theoretically itcould be used to support physic nut breeding program. However, onlylimited information has been available regarding molecular analysis ofphysic nut. The objectives of this research were: (i) to design SSR specificprimer based on DNA sequences available in the GenBank DNA databaseand (ii) to evaluate effectiveness of the primer pairs to produce polymor-phic SSR markers for J. curcas and J. multifida. Twenty eight primer pairswere designed and developed using physic nut DNA available in theGenBank DNA database. Total genomic DNA isolated from J. curcas andJ. multifida could be used as DNA templates for PCR amplification. Of the28 primer pairs developed in this research yielded SSR marker using J.curcas genomic DNA, while only 19 out of 28 pairs yielded SSR markersusing J. multifida genomic DNA. As many as 44 alleles with the size ofamplified products ranged from 100-360 bp were identified. Thirty fivealleles (79.5%) out of 44 identified ones were polymorphic. Results ofanalysis indicated that identified SSR markers generated using thedesigned primers were not polymorphic intra accession of J. curcas norintra-accession of J. multifida either. However, the generated SSR markerswere polymorphic for inter-accession of the two Jatropha species. Sincethe generated markers were only polymorphic for J. curcas and J.multifida, they could be used as markers for identifying interspecific F 1hybrids derived from crossing between J. curcas and J. multifida.Key words: Jatropha curcas L., physic nut, J. multifida, DNA repeatsequence, primer design

Abstract

ABSTRACTInterrelations among vegetative, generative and yield characters incoffee plantation is important in breeding and selection programs.Interrelationships among these characters are the causal model and it canbe analyzed by Sequential Path Analysis (SPA). This research was carriedout at Pakuwon Experimental Station located at 450 m above sea level, inLatosol soil type with B type of climate, from December 2010 to April2012. The objectives of this research is to analyze the direct or indirectinfluence of several vegetative and generative characters on yieldcharacters of Arabica coffee through the application of SPA and StructuralEquation Models (SEM). The observation method with systematicsampling on 40 Arabica coffee plants of Kartika 1 and Kartika 2 varietieswere used in this study. The results showed that the number of cherries ofArabica coffee var. Kartika 1 and 2 population in Pakuwon ExperimentalStation were affected directly by generative and indirectly by vegetativecharacters. Plant height and stem girth can be used as positive selectioncriteria for high yielding at vegetatite phase, while the character of widthcanophy can be used as negative selection criteria. In generative phase, thecharacter of quantity of productive branches and the amount of berries andflower cluster can be used as positive selection criteria.Keywords: Coffea arabica, selection, vegetative, generative, yield,sequential path analysis, structural equation modelsABSTRAKKeterkaitan antara karakter vegetatif, generatif dan hasil padatanaman kopi merupakan hal penting dalam program pemuliaan danseleksi.

Abstract

ABSTRAKSuatu bioassay telah dilakukan di Balai Penelitian TanamanRempah dan Obat Bogor, dari bulan November 2010 sampai dengan Maret2011, yang bertujuan untuk mengetahui potensi Heterorhabditis sp. dalammengendalikan Brontispa longissima. Nematoda dipanen dengan carameletakkan larva Tenebrio molitor mati terinfeksi nematoda patogenserangga (NPS) di atas kertas saring yang diletakkan di dalam cawan petriberisi 30 ml air. Juvenil infektif (JI) yang ada di dalam tubuh larva akankeluar dan hidup di dalam air. Suspensi JI kemudian dilarutkan 1.000 kalilalu populasinya dihitung di bawah mikroskop binokuler dan diulang 3kali. Populasi JI diperoleh dengan melarutkan 10 ml suspensi dengansejumlah air sehingga diperoleh populasi 7.000, 3.500, 1.750, 875, 438,dan 0 JI/ml air. Masing-masing perlakuan diujikan pada 10 ekor larva,pupa, dan imago dengan menyemprotkan 2 ml suspensi JI. Pengamatanmortalitas B. longissima dilakukan pada 24, 48, dan 72 jam setelahinfestasi (JSI). Hasil penelitian menunjukkan bahwa patogenisitasHeterorhabditis sp. tertinggi pada stadia larva diikuti imago dan pupa.Pada populasi 3.500 JI/ml air kematian larva, imago, dan pupa pada 24 JSIberturut-turut sekitar 73, 63, dan 10%, berbeda tidak nyata denganperlakuan 7.000 JI/ml air. LC 50  Heterorhabditis sp. terhadap larva, imago,dan pupa pada 72 JSI berturut-turut 1.492, 2.622, dan 800.818 JI/ml air.Kata kunci: Brontispa  longissima,  kelapa,  Heterorhabditis  sp.,patogenisitasABSTRACTIn order to evaluate the potensial of Heterorhabditis sp. incontrolling B. longissima bioassays was conducted in IndonesianResearch Institute for Spices and Medicinal Crops, Bogor from November2010 until March 2011. Infective juveniles (IJ) of the nematodes wereharvested by putting dead Tenebrio molitor on a filter paper placed in apetri dish containing 30 ml of water. IJs in the larval body will then go outand live in the water. The suspension was then diluted 1,000 times andthen population counted under a binocular microscope and repeated 3times. IJ population is obtained by dissolving 10 ml suspension to obtain7,000; 3,500; 1,750; 875; 438; and 0 IJs/ml of water. Each treatment wastested on 10 larvae, pupae, and adults by spraying 2 ml IJ suspension.Mortality observations were made at 24, 48, and 72 hours after infestation(HAI). The results showed that the highest Heterorhabditis sp.pathogenicity was found in larvae stadium followed by pupae and adultstadia. In the 3,500 IJ population/ml of water, larvae, imago, and pupaemortalities in 24 HAI were approximately 73, 63, and 10%, respectivelyand were not significantly different with 7,000 IJ/ml of water. LC 50 valuesof Heterorhabditis sp. on the larvae, adult, and pupae in 72 HAI were1,492; 2,622; and 800,818 IJ/ml of water, respectively.Key words: Brontispa longissima, Cocos nucifera, Heterorhabditis sp.,pathogenicity

Abstract

Carboxy methyl selulase and exo-polygalacturonase enzymes production and their role in determining the pathogenicity of Ralstonia solanacearum isolated from gingerBacterial wilt disease on ginger (Zingiber oicinale Roscoe) caused by Ralstonia solanacearum is the most destructive disease Infected tissues show macerated symptom on infected hosts indicating that the pathogen produces plant digestive enzymes. This research was aimed at analizing carboxymethylccllulasc (CMC-ase) and exopolygalacturonase (cxo-PG) enzymes production by the pathogen. In vitro production of CMC-ase of both virulent and avirulcnt isolates of R solanacearum was measured from diameter of clearing zone around bacterial colony on CMC medium whereas exo-PG was measured by the reduction of Na- polygalacturonatc by filtrate of the pathogen culture. Virulence of the pathogen was tested on tomato cultivar Gondol Hijau by pouring 50 ml of pathogen suspension (I07 cfu/ml) around roots of the plant and it was also tested on ginger cultivar Jahe Putih Besar by pricking suspension of pathogen into rhizome and basal pscudostcm of the plant. The results showed that CMC-ase and and PG-asc were produced by virulent isolates of R. solanacearum al 2.23 cm clear zone and 0.662 mg eq. glucose/ml/hour/ODiti, respectively. The avirulent isolates, however. correlated with disease intensity of the isolates. Disease intensity of the virulent isolates was 0.6 and 0.96 on tomato and on ginger plants respectively, whereas the avirulent isolates was 0.04 and 0.00 respectively. Therefore, CMC-ase and exo-PG are important in determining pathogenicity level of/?, solanacearum.
