    Panduan Karakterisasi Tanaman Pangan : Jagung dan Sorgum
    (Komisi Nasional Plasma Nutfah, 2004) Diterjemahkan Oleh Budiarti, Sri Gajatri; Silitonga, Tiur Sudiaty; Somantri, Ida Hanarida; Komisi Nasional Plasma Nutfah
    Salah satu mandat Balai Besar Penelitian dan Pengembangan Bioteknologi dan Sumberdaya Genetik Pertanian adalah menangani koleksi plasma nutfah pertanian. Untuk mendukung salah satu kegiatan pengelolaan plasma nutfah khususnya jagung dan sorgum maka karakterisasi plasma nutfah harus dilakukan dengan baik. Sehubungan dengan hal tersebut, untuk memudahkan kurator dan pengguna lain dalam karakterisasi jagung dan sorgum Komisi Nasional Plasma Nutfah menterjemahkan Panduan Karakterisasi Tanaman Jagung dari buku Descriptors for Maize yang diterbitkan oleh Centro International De Mejoramiento De Maizy Trigo/International Board for Plant Genetic Resources (CIMMYT/IBPGR) dan Races Maize in Brazil and Adjazent Areas yang diterbitkan oleh International Maize and Wheat Improvement Center, Mexico. Sedangkan Panduan Karakterisasi Tanaman Sorgum diterjemahkan dari buku Descriptor for Sorghum yang diterbitkan oleh International Board for Plant Genetic Resources dan International Crops Research Institute for the Semi-arid Tropics (ICRISAT).

    Status Plasma Nutfah Padi di Balai Penelitian Bioteknologi Tanaman Pangan, 1991-1998

    Rice Germplaons Collection at the Research Institute for Food Crop Biotechnology, 1991-1998. T.S. Silitonga. Rice germplasms are national assets that need to be well maintaned and conserved, because it plays an important role as a source of genes in breeding program for rice improvement. This is because improvement of rice varieties for high yield and quality as well as for adaptability to different agroecosystem is always faced with various biotic and abiotic constraints (factors). The use of high yielding, improved varieties is a major support in sustaining selfsufficiency for rice. Rapid spread of high yielding varieties has caused reduction in areas grown with local varieties. Now days, high yielding rice varieties has occupied more than 80% of the rice growing areas. This has resulted in genetic erosion on a number of local varieties that are adapted to specific agroecological condition. For this purpose, new rice germplasms need to be collected and conceived regurarly to prevent from extinction. The rice germplasms consisted of local, improved varieties, elite lines, wild relatives of rice, and introduction. At present RIFCB has 2.925 rice germplasm collection. Some of them have been evaluated and characterized for resistance to pest and diseases, tolerance to environmental conditions, as well as grain and cooking quality. Due to the close relationship between germplasms collection, breeding program, and biotechnology in modem agricultural development, rice germplasm programs is arranged according to the requirement of breeding program and agricultural development. To be more effective and efficient in conducting research development of food germplasm, it is necessary to conduct working mechanism and good coordination system nationally.
