Judul: Inheritance of quantitative characters of tomato (Lycopersicon esculentum Mill.) to lowland
Abstrak: The main problem of the cultivation of tomato plants in Indonesia is the limited varieties which have high yield potential, good fruit quality and well adapted at lowlands. The extensification in the highlands is quite difficult to do. Therefore low and medium land were subjected to the extensification for planting tomato in the future. The research involved three activities, i.e. (1) characterization of tomato germplasm and criteria selection for high tomato yield at lowlands, (2) estimation genetic parameters traits using diallel crosses and (3) performance of F1 tomato high yield at lowlands. The objective of the first activity was to obtain parental candidates for estimating genetic parameters with characterization using principal component analysis and clusters analysis. The germplasm of tomato was characterized into three groups, namely group I (IPBT1, IPBT4, IPBT8, IPBT13, IPBT58, IPBT83 and IPBT84), group II (IPBT3, IPBT23, IPBT30, IPBT33, IPBT34, IPBT53 and IPBT57) and group III (IPBT80). Good character used for the selection fruit of weight per plant at lowlands are weight per fruit and fruit size. The objective of second activity was to study of inheritance of both characters quality and quantity of tomatoes. The objective of third activity was to obtain a better hybrid of commercial hybrid varieties. The results showed there are no interaction between loci. Fruit length, fruit width, fruit size, weight per fruit, fruit flesh thickness, total soluble solid and weight of fruit per plant traits were influenced by additive and dominant factors. Number of locule and number of fruit per plant traits were influenced by additives factor. Broad and narrow sense heritability of all the characters were high. The parents which had a good general combining ability for fruit length, fruit width, fruit flesh thickness, fruit size, weight per fruit and fruit weight per plant were IPBT1, IPBT13 and IPBT84, whereas those for number of fruits per plant and number of locule were IPBT30 and IPBT33. Hybrid IPBT1 × IPBT13, IPBT84 × IPBT1, IPBT1 × IPBT84 were the best hybrids for high yield at lowlands, whereas IPBT33 × IPBT30 and IPBT30 × IPBT33 were the best hybrid for small tomatoes.

Judul: Yield Potential Test of Tomato (Solanum lycopersicum L.) Collection of PKHT IPB at Leuwikopo
Abstrak: Pengembangan varietas tomat di dataran rendah dapat menambah luas penanaman tomat, dan mengurangi tekanan penanaman di dataran tinggi yang berpotensi merusak kelestarian lingkungan. Varietas tomat dataran rendah yang unggul dapat meningkatkan produksi sehingga kebutuhan konsumsi tomat dapat tercukupi. Uji daya hasil dibutuhkan untuk menguji daya hasil galur-galur tomat yang telah ada, kemudian diseleksi untuk dikembangkan menjad varietas. Penelitian ini bertujuan untuk mendapat daya hasil genotipe tomat koleksi PKHT IPB. Penelitian dilakukan di Kebun Percobaan Leuwikopo, IPB, Dramaga, Bogor pada bulan April hingga Agustus 2013. Metode penelitian menggunakan Rancangan Kelompok Lengkap Teracak (RKLT), satu faktor dengan tiga ulangan. Faktor tersebut adalah 11 galur potensial tomat yang terdiri atas 3 varietas komersial (Intan, Ratna, dan Karina) sebagai pembanding.Genotipe yang diuji menujukkan keragaman sangat nyata untuk karakter bobot per buah, tinggi tanaman, lebar daun, jumlah buah per tanaman, panjang buah, dan diameter buah, serta nyata untuk karakter tebal daging, panjang daun dan umur berbunga. Tidak terdapat perbedaan pada karakter diameter batang, umur panen, bobot buah pertanaman dan produktivitas. Karakter bobot perbuah genotipe IPBT8, IPBT43, IPBT57, IPBT60, IPBT64 dan IPBT78 tidak berbeda dengan varietas pembanding. Karakter jumlah buah pertanaman genotipe IPBT3, IPBT30, IPBT33, dan IPBT53 menunjukkan jumlah lebih banyak dibandingkan varietas pembanding. Genotipe tomat yang memiliki daya hasil lebih baik dari genotipe lainnya adalah genotipe IPBT8., The development of tomato varieties in the lower elevation lands is important for increasing the area of planting tomatoes, and reduce the pressure of planting in the highlands that have the potential to damage environmental sustainability. The superior low land tomato varieties can increase production so that tomato consumption needs can be fulfilled. The trial results are needed to identify the potential of the existing tomato genotype. This research aimed to obtain the information of the tomato genotype collection of PKHT-IPB. The experiment was conducted at Leuwikopo Field Station, IPB, Dramaga, Bogor from April to August 2013. The genotype was arranged in Randomized Complete Block Design (RCBD), with three replications. The tomato genotypes that used in this experiment consist of 11 potential genotypes and 3 commercial varieties (Intan, Ratna, and Karina) as control varieties. The tested genotypes showed very significantly differences for the character of fresh weight per fruit, plant height, leaf width, fruit number per plant, fruit length, and fruit diameter, and significantly differences for the character of fruit flesh thickness, leaf length, and flowering time. There were no differences on the character of stem diameter, harvesting time, fresh weight per plant and productivity.The character of fresh weight per fruit of IPBT8, IPBT43, IPBT57, IPBT60, IPBT64 and IPBT78 similar to the control varieties. The character of fruit number per plant of IPBT3, IPBT30, IPBT33, and IPBT53 show more number than the control varieties. Tomato genotypes that have a better yield ability than other genotypes were IPBT8.

Judul: Infeksi Virus Parainfluenza Pada Anjing
Abstrak: Virus parainfluenza anjing termasuk famili Paramyxoviridae, berbentuk pleomorf dengan ukuran bervariasi (bergaris tengah antara 100-500 nm), berpembungkus peka ether, berisi genom RNA dan secara serologis mempunyai kesamaan dengan virus SV-5 kera; dikenak sebagai salah satu kausa penting dari sindrom "kennel cough". Infeksinya dapat mengenai anjing semua umur yang belum pernah terinfeksi atau mendapatkan vaksinasi mengakibatkan gejala klinis ringan yang terbatas pada traktus respirasi atu infeksi yang secara klinis tidak memperlihatkan gejala nyata. Gejala klinis yang nampak setelah masa inkubasi (1-5 hari) terlewati berupa batuk yang tidak berat selama beberapa hari, berbagai tingkat tonsilitis dan pharyngitis dan kadang-kadang ditemukan kenaikan temperatur rektal antara 1-2 derajat C dari temperatur normal rat-rata. Anjing terinfeksi mengandung virus pada traktus respirasi bagian atas dan bawah serta limfonoduli sampai hari ke 9 setelah infeksi. Penyebaran virus antar anjing terjadi secara aerogen.
