Abstrak: Anther culture is one of rice breeding method which is efficient in time, cost and labor. Conventional rice breeding usually needs 10 generations to achieve homozigous pure lines. Anther culture can reduce the time to only 1-2 generations. The objective of this research was to obtain doubled haploid or dihaploid plants (DH0) produced from rice anther culture of F1. The materials used in this research were anthers of F1 from some lowland rice and upland rice crosses i.e 1) IR85640-114-2-1-3 x I5-10-1-1, 2) Bio-R81 x I5-10-1-1, 3) Bio-R81 x O18b-1 and 4) Bio-R82-2 x O18b-1. The result from this research were 265 green plants (34% from the total plants) consisted of 34 green plants from (IR85640-114-2-1-3 x I5-10-1-1) , 59 green plants from (Bio-R81 x I5-10-1-1), 77 green plants from (Bio-R81 x O18b-1) , and 95 green plants from (Bio-R82-2 x O18b-1). The green plants were acclimatized, grown in the greenhouse and selected to obtain first generation of dihaploid plants. This research yielded 15, 11, 21, and 26 doubled-haploid (DH0) lines from IR85640-114-2-1-3 x I5-10-1-1, Bio-R81 x I5-10-1-1, Bio-R81 x O18b-1, and Bio-R82-2 x O18b-1 respectively.

Abstrak: The objectives of this research were to obtain information the agronomy characters and yield potential of upland rice lines obtained from anther culture. An experiment was conducted at Sawah Baru Experiment Station, Babakan, Dramaga, Bogor in December 2014 - April 2015. Eighteen dihaploid lines and three check varieties namely Limboto, Inpari 13, and Situ Bagendit were evaluated. The research was arranged in completely randomized block design (RCBD) with three replications. There were 63 experiment of units with the size of each unit 0.6 x 3 m. The highest productivity was achieved by HR-1-12-1-1 (3.0 ton/ha) higher than Inpari 13 (1.9 ton/ha) dan Situ Bagendit (2.0 ton/ha). HR- 1-12-1-1, HR-1-32-1-1, HR-2-21-2-1, HR-2-27-2-7, HR-2-34-1-3, HR-5-9-1-1, and HR-5-13-2-2 had the same potential productivity with Limboto. This lines had the agronomy characters : height of plant (76.4 - 102.8 cm), the number of productive tiller (12.8 - 22.4), age of harvest ( 110 - 119 DAP), the number of grains/panicle (123.5 – 195.0 grains), weight of 1 000 grains (19.9 - 26.5 g), and productivity (2.4 - 3.0 ton/ha).

Judul: Studi Kasus: Patomorfologi Trakheobronkhitis Supurativa Pada Kucing (Felis Catus).
Abstrak: Trakheobronkhitis merupakan penyakit saluran respirasi yang sering terjadi pada hewan kecil, terutama anjing dan kucing. Penelitian berupa studi kasus ini bertujuan untuk mempelajari patomorfologi trakheobronkhitis supurativa pada kucing. Perubahan patologi anatomi berupa eksudat purulen pada lumen trakhea dan warna paru-paru yang tidak homogen, warna lebih gelap pada salah satu lobus, dan permukaan paru-paru lebih menonjol. Perubahan histopatologi berupa badan inklusi amfofilik-eosinofilik intranuklear yang dikelilingi oleh clear halo dan titik-titik kromatin ditepinya pada epitel kelenjar trakhea dan epitel bronkhiolus. Badan inklusi ini merupakan ciri dari FHV-1 dan adenovirus. Pada trakhea juga ditemukan koloni bakteri berbentuk coccobacillus sebagai infeksi sekunder. Bakteri tersebut diduga Bordetella sp. yang sering menginfeksi saluran respirasi kucing. Deskuamasi terjadi pada epitel trakhea dan bronkhiolus. Selain itu, ditemukan juga sel radang limfosit, makrofag, sel plasma, dan neutrofil. Pada paru-paru ditemukan lesio bronkhiolitis. Ditemukan juga bronkhopneumonia yang ditandai infiltrasi sel radang neutrofil dan sel nekrosis pada lumen bronkhiolus. Paru-paru juga mengalami emfisema dan edema pulmonum. Hiperemia dan hemoragi juga ditemukan pada kapiler paru-paru. Pada kasus ini, trakheobronkhitis supurativa diduga disebabkan oleh FHV-1, adenovirus, dan bakteri jenis Bordetella sp.
