Abstract

Path Analysis of Agronomic Characters and Resistance to Pod Sucker Bug on Yield of Soybean Germplasm. Asadi. Soybean productivity was still low and unstable that commonly caused by pest attack and disease. Pod sucking insect pest is most serious pest of soybean that reduce seed production. Riptortus linearis is the most dominant pest of pod sucking bug of soybean. Planting of resistant variety is one of the biological control. To support the soybean breeding program for pod sucking pest resistance, the availability of sources of resistance genes is needed. Sources of resistance genes are obtained by evaluating and identifying of soybean germplasm. Based on soybean germplasm evaluation, it can be identified sources of resistance genes that can be used as the base material of soybean breeding programs for pod sucking pest resistance. How influence of independent variable (Xi) such as agronomic characters and resistance to pod sucking on seed yield as the dependent variable (Yi) of soybean germplasm, can be estimated by path analysis. By knowing the characters that influence the seed yield directly, so the character is going to be used for selection of soybean yield of germplasm. Based on 103 evaluations of soybean germplasm, as much as 5 accessions (B3778, B4400, B3802, B4176, and B2973) were identified as the resistant accessions, while accessions B4142, B4417 (Panderman), and the B3462 were most susceptible to pest of pod sucking bug. The seed size or pod size of soybean germplasm correlated positively and significantly on resistance to pod sucking bug. Multiple regression analysis indicated that the plant height (X3), and pod sucking bug attack (X7) significantly affect seed yield of soybean germplasm. The higher plant, the lower pod sucking bug attack, the higher soybean yield. Path analysis showed that plant high character (X3) affected the seed yield of soybean germplasm directly, indicating that the plant high character can be used for the selection of seed yield of soybean germplasm. Number of pods per plant (X5) by the effect of plant high (X3) affects the grain yield (Y) of soybean germplasm indirectly. AbstrakProduktivitas kedelai yang masih rendah dan beragam disebabkan antara lain oleh masih tingginya serangan hama dan penyakit. Pengisap polong tergolong hama utama yang cukup serius mempengaruhi hasil kedelai. Reptortus linearis merupakan hama yang paling dominan menyerang tanaman kedelai. Penggunaan varietas tahan merupakan salah satu cara pengendalian yang ramah lingkungan. Untuk mendukung program pemuliaan kedelai terhadap ketahanan hama pengisap polong, ketersediaan sumber gen tahan sangat diperlukan. Sumber gen tahan diperoleh dengan cara mengevaluasi dan mengidentifikasi sejumlah plasma nutfah kedelai yang tersedia. Dari hasil evaluasi diharapkan akan teridentifikasi sumber gen tahan yang dapat digunakan sebagai bahan dasar untuk program pemuliaan kedelai terhadap ketahanan hama pengisap polong. Sebarapa jauh pengaruh karakter agronomi dan ketahanan terhadap hama pengisap polong sebagai variabel bebas (Xi) terhadap hasil biji sebagai variabel tak bebas (Yi) pada plasma nutfah kedelai dapat diketahui melalui analisis lintasan. Dengan mengetahui karakter yang berpengaruh langsung terhadap hasil, maka karakter tersebut dapat digunakan untuk seleksi terhadap hasil kedelai. Berdasarkan hasil evaluasi 103 plasma nutfah kedelai, sebanyak lima aksesi telah diidentifikasi (B3778, B4400, B3802, B4176, dan B2973) sebagai aksesi yang tahan, sedangkan aksesi B4142, B4417 (Panderman), dan B3462 termasuk paling rentan terhadap hama pengisap polong. Ukuran biji yang dicerminkan oleh besarnya polong berkorelasi positif dan nyata dengan kerentanan terhadap hama pengisap polong. Analisis regresi berganda mengindikasikan bahwa tinggi tanaman (X3) dan tingkat serangan hama pengisap polong (X7) berpengaruh nyata terhadap hasil biji kedelai. Semakin tinggi tanaman dan semakin rendah serangan hama pengisap polong maka semakin tinggi hasil. Analisis sidik lintas menunjukkan bahwa sumbangan tinggi tanaman (X3) besar dalam menentukan hasil (Y). Artinya, karakter tinggi tanaman dapat digunakan untuk seleksi terhadap hasil biji kedelai. Jumlah polong per tanaman (X5) tidak langsung menentukan hasil biji (Y) kedelai dengan adanya peran tinggi tanaman (X3).

Abstract

Timor deer (Rusa timorensis de Blainville 1822) known as java deers are native Indonesian fauna, mostly found ex situ. Deers in captivity can be an attraction object of tourism. The research was conducted from March to April 2013 at Dramaga Research Forest, Situ Gede Village, Bogor City. Dramaga research forest was build on 1956 as an arboretum with 127 tree species. The purpose of this research was to identify deer feed given by visitors in captivity, changes in behavior and consumption patterns. The feed given by visitors to deer was about 89% convolvulus, 8% carrots, 2% leaves, and 1% wild grasses. The feed meets the basic needs of a deer with convolvulus containing 8,93% protein and carrots containing 19,99% protein. The results of statistical test by chi-square indicate that no real influence on the behavior and consumption patterns of the deers in captivity, but nominally show some changes decrease of persentation. Consumption pattern and social behaviour increased, while resting, locomotion, and ruminational behaviours decreased. AbstrakRusa timor (Rusa timorensis de Blainville 1822) merupakan rusa asli Indonesia yang populasinya banyak ditemukan di luar habitat aslinya, khususnya di penangkaran. Rusa dapat menjadi daya tarik wisata di penangkaran, karena tampilannya yang menarik. Penelitian dilakukan pada bulan Maret sampai April 2013 di Hutan Penelitian (HP) Dramaga, Kelurahan Situ Gede, Kecamatan Bogor Barat, Kota Bogor. Hutan Penelitian Dramaga dibangun tahun 1956 dengan tujuan sebagai koleksi tanaman dengan 127 jenis pohon. Tujuan penelitian ini adalah mengidentifikasi pakan rusa yang diberikan pengunjung di penangkaran Dramaga, perubahan perilaku dan pola konsumsi. Metode pengumpulan data melalui pengamatan langsung di lapang dengan focal animal sampling dan metode pengambilan data one-zero sampling terhadap perilaku dan pola konsumsi rusa, wawancara dengan pengunjung serta studi pustaka. Hasil penelitian menunjukkan bahwa jenis pakan yang diberikan oleh pengunjung meliputi 89% kangkung, 8% wortel, 2% daun-daun, dan 1% rumput lapang. Jenis pakan memiliki nilai gizi yang dapat mencukupi kebutuhan rusa di penangkaran. Hasil uji statistik menunjukkan bahwa pemberian pakan oleh pengunjung tidak berpengaruh terhadap perubahan perilaku dan pola konsumsi harian rusa. Tetapi secara nominal menunjukkan adanya perubahan perilaku makan dan sosial yang meningkat, perilaku istirahat, lokomosi, dan mamah biak yang menurun. Perubahan tersebut berpengaruh pada kegiatan biologis rusa, dan diduga dapat mengganggu kesehatan.

Abstract

Identification of Early Maturing and High Yielding Soybean Germplasm. Preference to early maturing soybeans is higher than the late ones, since early maturing soybean can improve planting index and able to escape from fail of harvest due to drought stress. To identify accessions of soybean germplasm which will be used as gene resources in developing of early maturing and high yielding varieties, a numbers of 203 soybean germplasm accessions were evaluated at Jambegede Research Station on dry season 2006. Observation primarily conducted on physiological maturity and flowering date. Beside, observation also conducted on plant height, number of branches, 100 seeds weight and seed yield. Result showed that accession of MLGG 0751 and MLGG 0753 identified having early maturity (70 days). The early maturing accessions had lower yield than the late maturing ones. There was no accession having both of early maturing and high yielding traits. Accessions of MLGG 0751 and MLGG 0753 can be used as gene resources in developing of early maturing varieties. AbstrakPreferensi terhadap kedelai berumur genjah lebih tinggi daripada berumur dalam karena kedelai berumur genjah dapat meningkatkan indeks pertanaman dan dapat menghindari kegagalan panen akibat cekaman kekeringan. Untuk mengidentifikasi aksesi plasma nutfah yang akan digunakan sebagai sumber gen dalam perakitan varietas kedelai berumur genjah dan berdaya hasil tinggi, sebanyak 203 aksesi plasma nutfah kedelai dievaluasi di Kebun Percobaan Jambegede pada musim kemarau 2006. Pengamatan terutama dilakukan terhadap umur masak fisiologis dan umur berbunga. Pengamatan juga dilakukan terhadap tinggi tanaman, jumlah cabang, bobot 100 biji, dan hasil biji tanaman. Hasil penelitian menunjukkan bahwa aksesi MLGG 0751 dan MLGG 0753 teridentifikasi berumur genjah (70 hari). Aksesi berumur genjah memiliki hasil biji lebih rendah daripada aksesi berumur dalam. Tidak diperoleh aksesi kedelai berumur genjah yang sekaligus berdaya hasil tinggi. Aksesi MLGG 0751 dan MLGG 0753 dapat digunakan sebagai sumber gen dalam perakitan varietas kedelai berumur genjah.

Abstract

The main constraint encountered in theutilization of plant genetic resources (PGR) in agriculture arebiotic stresses such as insect pests, plant diseases, and plantparasitic nematodes. The application of genetic engineeringtechniques create a great opportunity for crops improvementsparticularly for insect and plant diseases resistance. Throughgenetic engineering, genetically engineered (GE) crops havebeen developed, of which having the new traits such as resistanceto insect pests, plant diseases, and herbicide tolerance.GE crops are already widely grown and marketed in manycountries. Globally, GE crops that are commercialized consistsof four categories of traits, which are insect resistance (IR),herbicide tolerance, (HT), the combined traits of IR and HT(stacked genes), and virus resistance. Initially, GE crops hadbeen commercialized globally covering 1.7 million ha in 1996,and the cropping area increased rapidly to reach about 134million ha in 2009. Indonesia is known as a country rich inPGR, that have very high value. One of environmentallyfriendly technologies that can be applied in the utilization ofPGR in Indonesia, is genetic engineering. In Indonesia,research on plant genetic engineering had started since 1997.Commodities that are being researched to develop GE plantslimited on rice, potatoes and tomatoes. GE rice resistant tostem borer (Scirpophaga incertulas), GE potato resistant tolate blight (Phytophthora infestans), and GE tomato resistantto tomato yellow leaf curl virus (TYLCV) and cucumbermosaic virus (CMV) have been successfully developed byResearch Center for Biotechnology of Indonesian Institute ofScience and Indonesian Center for Agricultural Biotechnologyand Genetic Resources Research and Development(ICABIOGRAD). Those GE crops have been tested for theirresistance at the screenhouses, green houses of the biosafetycontainment, and confined field trial.

Abstract

Inheritance of Several Qualitative Characters in Three Group Pepper. Selection method is one of most important factors in determining the success of pepper breeding programs. Selection method will be effective if it is supported by a complete knowledge of genetic character inheritance. This research was aimed to investigate the information of inheritance pattern of pepper adaptability to qualitative characters. There are two steps in this research i.e makes material genetic and inheritance study of qualitative characters in the field. The result showed that all characters qualitative controlled one gen. There are several characters qualitative that depended action gen full dominant (colour young length and fruit textur) and others characters depended action gen partial dominant (colour young fruit and flower position). AbstrakMetode seleksi adalah salah satu faktor penting yang menentukan keberhasilan pemuliaan cabai. Metode seleksi akan lebih efektif jika didukung oleh pengetahuan yang lengkap tentang pola pewarisan karakter genetik. Penelitian ini bertujuan untuk mengetahui pola pewarisan yang sesuai untuk karakter-karakter kualitatif. Penelitian ini berlangsung dua tahap, yaitu pembentukan materi genetik dan studi pewarisan karakter kualitatif di lapang. Hasil penelitian menunjukkan semua karakter kualitatif dikendalikan oleh satu gen. Ada beberapa karakter kualitatif yang dipengaruhi oleh gen dominan penuh (warna batang muda dan tekstur permukaan buah) dan karakter lainnya dipengaruhi oleh gen dominan sebagian (warna buah muda dan posisi bunga).
