Judul: Agronomic Performance of IPB Promising Lines for Rice (Oryza sativa L.) Productivity Improvement.
Abstrak: Konsumsi beras yang tinggi dan semakin meningkatnya jumlah penduduk Indonesia menjadi tantangan upaya peningkatan produktivitas tanaman padi. Penelitian ini bertujuan membandingkan penampilan agronomi serta produktivitas padi galur harapan IPB. Penelitian dilakukan pada September 2022 hingga Januari 2023 di Kebun Percobaan Sawah Baru, IPB Dramaga, Bogor, Jawa Barat. Penelitian ini menggunakan rancangan kelompok lengkap teracak dengan lima perlakuan dan tiga ulangan. Perlakuan yang diuji berupa empat galur harapan IPB dan varietas IPB 3S yang ditanam menggunakan sistem jarwo 4:1. Galur padi yang digunakan yaitu AR18, FK22, H56, H88, dan varietas IPB 3S sebagai tanaman pembanding. Hasil penelitian menunjukan bahwa penampilan agronomi empat galur harapan IPB terhadap varietas IPB 3S tidak menunjukkan perbedaan tinggi tanaman, jumlah anakan, bobot kering tajuk, SPAD, luas daun bendera, laju fotosintesis, sudut kemiringan daun bendera, jumlah malai per rumpun, jumlah dan bobot gabah per rumpun, jumlah dan bobot gabah isi per rumpun, persentase gabah isi, dan bobot 1000 butir. Umur berbunga varietas IPB 3S lebih cepat dibandingkan AR18 dan FK22 dan tidak berbeda dengan H56 dan H88. Proyeksi produktivitas empat galur harapan IPB berkisar 7,92 - 11,24 ton/ha, tidak berbeda dengan IPB 3S (9,55 ton/ha). Galur H56 dapat diuji lanjut di lapangan karena menunjukkan keunggulan potensi hasil, bobot 1000 butir yang tinggi, ukuran daun bendera yang besar dan umur berbunga yang sama dengan IPB 3S., Increasing rice consumption as the consequence of the increasing population in Indonesia are a challenge for efforts to increase rice productivity. This research aims to compare the agronomic performance and productivity of IPB promising lines. The research was conducted from September 2022 to January 2023 at the Sawah Baru Experimental Field, IPB Dramaga, Bogor, West Java. This study used a completely randomized block design with five treatments and three replications. The treatments tested included four genotypes of IPB promising lines and IPB 3S planted using a 4:1 row ratio system. The rice genotypes used were AR18, FK22, H56, H88, and IPB 3S as a comparison variety. The results showed that the agronomic performance of four promising lines IPB compared to the IPB 3S variety showed no significant differences in plant height, number of tillers, shoot dry weight, SPAD, flag leaf area, photosynthetic rate, leaf angle, flag leaf leght, number of panicles per hill, number and weight of grains per hill, number and weight of filled grains per hill, percentage of filled grains, and 1000- grain weight. However, variations were observed in flowering time, with the IPB 3S variety flowering earlier than AR18 and FK22, however IPB 3S deading time showed no different with H56 and H88. The projected productivity of the four IPB promising lines ranged from 7.92 to 11.24 tons/ha, showed no different with IPB 3S (9,55 ton/ha). Line 56 could be recommended for further field trial since the line showed high potential yield, 1000 grains weight, a long flag leaf, and the same duration of heading time with IPB 3S.

Judul: Preliminary Yield Trial of 84 Lowland Rice Lines (Oryza sativa L.) of F5 and F6 Generation.
Abstrak: Beras merupakan sumber karbohidrat utama masyarakat Indonesia. Peningkatan potensi produktivitas padi untuk mencukupi kebutuhan masyarakat terus dilakukan melalui perbaikan mutu dengan kegiatan pemuliaan tanaman dimana salah satu tahapannya yaitu uji daya hasil pendahuluan. Penelitian ini bertujuan menguji daya hasil dan keragaan galur harapan padi generasi F5 dan F6 untuk memperoleh galur yang memiliki daya hasil dan karakter agronomi lebih baik sebagai galur yang akan diuji pada tahapan berikutnya. Penelitian dilaksanakan pada bulan Februari hingga Juli 2023 di Kebun Percobaan Sawah Baru, Kecamatan Dramaga, Bogor dan Laboratorium Pemuliaan Tanaman. Percobaan menggunakan Rancangan Kelompok Lengkap Teracak faktor tunggal dengan 84 galur dan 2 varietas pembanding sebagai perlakuan. Hanya galur IPB200-F-42 dengan daya hasil nyata lebih tinggi daripada Inpari 32 (4,58 ton ha-1) dengan produktivitas sebesar 7,16 ton ha-1, namun tidak berbeda nyata dengan Ciherang (5,21 ton ha-1) berdasarkan analisis statistik. Meskipun demikian, terdapat galur yang cenderung memiliki produktivitas lebih tinggi daripada varietas pembanding berdasarkan nilai rataan serta memiliki karakter agronomi sesuai dengan kriteria PTB. Galur-galur tersebut yaitu IPB200-F-2, IPB200-F-14, IPB200-F-15, IPB200-F-17, IPB204-E-6, IPB200-F-21, IPB200-F-22, IPB200-F-25, IPB204-E-10, IPB201-F-16, IPB200-F-43, IPB200-F-44, IPB187-F-40-1-1., Rice is the main source of carbohydrates for Indonesian people. Increasing the potential for rice productivity to meet community needs continues to be carried out through quality improvement through plant breeding activities, where one of the stages is preliminary yield testing. This study aims to test the yield and performance of the expected lines of F5 and F6 generations of rice in order to obtain lines that have better yield and agronomic characteristics as lines to be tested in the next stage. The research was conducted from February to July 2023 at the Sawah Baru Experimental Garden, Dramaga District, Bogor, and the Plant Breeding Laboratory. The experiment used a single factor randomized block design with 84 lines and two control varieties as treatments. IPB200-F-42 is the only one line which had significantly higher yields than Inpari 32 (4.58 tons ha-1) with a productivity of 7.16 tons ha-1, but was not significantly different from Ciherang (5.21 tons ha-1) based on statistical analysis. Nonetheless, there are lines that tend to have higher productivity than the control varieties based on the average value and have agronomical characteristics according to the PTB criteria. These lines are IPB200-F-2, IPB200-F-14, IPB200-F-15, IPB200-F-17, IPB204-E-6, IPB200-F-21, IPB200-F-22, IPB200-F-25, IPB204-E-10, IPB201-F-16, IPB200-F-43, IPB200-F-44, IPB187-F-40-1-1.

Abstrak: A cat was found with several critical conditions such as skin ulceration, exophthalmus, anorexia, cachexia, dyspnoe, anemia, constipation, and severe dehydration. The cat was well-treated with some medications but it failed. Radiographs show that diaphragm line was not seen with some abdominal contents displacement into the thoracic cavity. Necropsy study revealed many lesions in characteristic of congenital diaphragmatic hernia due to diaphragm anomalies. Histopathologically, congestion and other lesions were found in heart, lungs, liver, kidneys, spleen, lymph node, and brain. Those lesions were found due to negative pressure effect which moved the intestine and a part of liver into the thoracic cavity. Therefore, the heart and lungs could not work normal then consequence of the death was caused by congestive heart failure.
