Judul: Daya gabung dan heterosis komponen hasil serta keragaan tomat (Lycopersicon esculentum Mill) hasil persilangan half diallel
Abstrak: The aim of this research was to study estimation of the general combining ability (GCA), the specific combining ability (SCA), the heterosis and the heterobeltiosis of fifteen hybrids and performances of tomato (Lycopersicon esculentum Mill.) in half diallel crosses. This research was conducted at Genetic and Plant Breeding Laboratory and IPB Experimental Field, Leuwikopo, Dramaga, Bogor, from March-July 2013. The experimental design used was randomized complete block design (RCBD) single factor with three replications. Plant materials were six tomato inbred lines, fifteen hybrids from hybridization half diallel crosses and three commercial hybrids. Genotype IPB T3 x IPB T73, IPB T13 x IPB T64 had the best combining ability, heterosis, heterobeltiosis and performances in several traits observed.

Judul: Heterosis dan Daya Gabung pada Persilangan HalfDiallel Cabai Besar dan Cabai Keriting (Capsicum annuum L.)
Abstrak: The aim of this research was to study estimation the heterosis and heterobeltiosis of fifteen hybrids, the general combining ability (GCA), and the specific combining ability (SCA) of six chili inbred lines of hybridization between big and curly pepper (Capsicum annuum L.). This research was conducted at Genetic and Plant Breeding Laboratory and IPB Experimental Field, Leuwikopo, Dramaga, Bogor, from September 2012 to March 2013. The experimental design used was randomized complete block design (RCBD) single factor with three replication. Plant materials were six chili inbred lines, fifteen hybrids from hybridization half diallel crosses, and two commercial hybrids. Genotype IPB C159 x IPB C120, IPB C159 x IPB C111, IPB C159 x IPB C5, IPB C120 x IPB C5, IPB C111 x IPBC2, IPB C19 x IPB C5, and IPB C5 x IPB C2 had positive heterosis, heterobeltiosis, and SCA values for some variables observed. All these genotypes had advantages that were better than the comparison of varieties TM 999 and Gada on some characters observed

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.
