High Quality Seed

Seed production of field crops plays a key role in ensuring food security of the country and is a continuation of the selection process, a necessary link for the development and maintenance of the variety. In seed production, the main object is a variety that is genetically close to each other a certain group of plants, homogeneous in morphological and biological properties. The finish of high-quality seed production is seeds with good varietal and sowing qualities. The main condition for effective production of field crops is a well-established seed production system, which is a set of functionally interconnected structures engaged in the production of elite and reproductive seeds. Seed production of field crops solves two main tasks: variety exchange and variety renewal. When a variety is changed, one zoned variety is replaced by another with more valuable economic characteristics. During variety renewal, varietal seeds in farms are replaced with seeds of the same varieties, but of higher reproductions. Usually, seeds for cereals and legumes are updated every 3-4 years, for millet - every 2 years, for sunflower - annually. The main goal of seed production of field crops is to maintain a set of characteristics of the variety, its most valuable qualities and economic indicators.

<p>Bawang merah merupakan komoditas penting dan bernilai ekonomi tinggi untuk Indonesia. Upaya untuk meningkatkan produktivitas bawang merah sesuai dengan potensi hasilnya terus diupayakan, namun terkendala oleh ketersediaan benih bawang merah bermutu dalam jumlah cukup sepanjang tahun bagi petani. Untuk mengatasi hal tersebut diupayakan dengan memproduksi biji botani bawang merah (true shallot seed =TSS). Penelitian sebelumnya menyatakan penggunaan TSS potensial untuk mengurangi biaya benih dan meningkatkan hasil panen bawang merah. Tujuan penelitian untuk mengetahui kelayakan finansial produksi biji botani bawang merah/TSS di tiga provinsi di Indonesia. Penelitian dilakukan pada bulan Juni hingga Desember 2016 di Desa Gurgur, Kecamatan Tampahan, Kabupaten Tobassa, Sumatera Utara, Desa Tulungrejo Kecamatan Bauji Kota Batu, Jawa Timur, dan di Desa Gumeng, Kecamatan Jenawi, Kabupaten Karang Anyar, Jawa Tengah. Analisis data menggunakan analisis biaya usahatani dan pendapatan. Hasil penelitian menunjukkan bahwa produksi TSS di Sumatera Utara dan Jawa Timur memberikan keuntungan yang sangat baik, yakni sebesar 602,7 juta dan 356,3 juta rupiah dengan nilai R/C berturut-turut 3,44 dan 2,63. Sementara itu produksi TSS di Jawa Tengah mengalami kerugian, dengan nilai kerugian sebesar 184,3 juta rupiah dengan nilai R/C 0,41.</p><p><strong>Keywords</strong></p><p>Kelayakan finansial; TSS; Produksi bawang merah; Analisis usahatani</p><p><strong>Abstract</strong></p><p>Shallot is an important crop that has high economic value for Indonesia. Efforts for increasing shallot productivity to fit its potential yield are continuously pursued. However, these efforts are mostly constrained by the availability of high quality shallot bulb seed and its accessibility to be used by farmers along the year. An alternative planting material that recently has been promoted is the use of true shallot seed (TSS). Preliminary findings suggest a promising potential of TSS use because it may not only reduce the seed costs, but also may increase the yield. The objective of this study was to assess the financial feasibility of TSS production in three provinces of Indonesia. The study was conducted from June to December 2016 in (1) Gurgur Village, Tampahan Subdistrict, Tobassa District, North Sumatera, (2) Tulungrejo Village, Bauji Subdistrict Batu, East Java, and in (3) Gumeng Village, Jenawi Subdistrict, Karang Anyar District, Central Java. Data were analyzed by using an enterprise budget method. The results suggest that TSS production in North Sumatera and East Java provides positive profit as much as IDR 602.7 million (R/C = 3.44) and IDR 356.3 million (R/C = 2.63), respectively. Meanwhile, because of unfavorable climatic condition, TSS production in Central Java experiences a loss as much as IDR 184.3 million, with the R/C of 0.41.</p>

Potato Collection

Background. VIR’s potato collection is one of the oldest and richest; however, it is constantly exposed to viruses that negatively affect useful agronomic properties of tubers. Close monitoring of the phytosanitary state of potato accessions helps to select the most effective method of therapy for subsequent healing of infected plants and obtaining high-quality planting material.Materials and methods. The research was aimed at improving the health of 18 varieties of Solanum tuberosum L. from the VIR collection. Testing for the presence of viruses was based on the ICA and RTPCR techniques, and the consequent healing was performed using the methods of meristem culture and cryotherapy.Results and conclusions. During the field test of potato plants, PVX, PVS and PVA were found to be the most common viruses. PSTVd was completely absent in all tested accessions. The effectiveness of in vitro healing of potato plants from viruses was assesses using meristem culture. The percentage of healed plants was 0% for PVS, 0% for PVX, 33.4% for PVA, 50% for PLRV, 72.3% for PVY, and 83.4% for PVM. Healing with meristem culture was shown to be the most effective against PVY and PVM. While assessing the effectiveness of post-cryogenic restoration of potato microplants, the level of post-cryogenic regeneration of the shoot tips in potato microplants was determined at 22.3% on average for a sample. The minimum was observed in k-16762 ‘Sagita N’ (5%), and the maximum in k-1378 ‘Marta’ (41.7%). Analysis of the effectiveness of potato recovery from viruses by in vitro cryotherapy showed that the percentage of recovered plants was 100% for PVY, 100% for PVA, 88.9% for PVM, 77.8% for PVS, 44.4% for PVX. Thus, the techniques of apical meristem culture and cryotherapy proved to be effective against PVY, PVA and PVM viruses. However, in the case of multiple infections, it is necessary to combine elements of different healing protocols to increase the effectiveness of the healing procedure.

Active Regeneration

In conditions of a sharp reduction in the stocks of traditional fuels, it is important to find new efficient and renewable carbon-neutral energy sources. One of the most promising sources of renewable energy is the biomass of woody plants, in particular the family Willow (Salicaceae Mirb.). Traditionally, Salicaceae plants are propagated by generative and vegetative methods. Microclonal propagation, in contrast to traditional methods of reproduction, allows to obtain genetically homogeneous healthy planting material throughout the year. A significant number of biotechnological publications focus on the development of the optimal protocol for the reproduction of plants of the family Salicaceae, the study of the morphogenetic potential of tissues and optimizing their growth. However, the authors note the individually determined regenerative ability of plant material in vitro, which depends on a number of factors. The purpose of the study is to analyze the results of biotechnological research on the effectiveness (possibility) of obtaining high-quality planting material of plants of the family Salicaceae by tissue in vitro. For this purpose, we used the results of biotechnological studies of plant tissues of the family Salicaceae in vitro by foreign and domestic authors published in professional journals during 2010−2020. Research methods − analysis, comparison, synthesis, generalization. The analysis revealed that the sterilization regime of Salicaceae plant material depends on the type of explant, phenological phase and age of the donor plant. Step-by-step sterilization using mercury chloride, sodium hypochlorite and silver nitrate effectively neutralizes the exogenous biota of woody explants. The stage of active vegetation is the optimal period of isolation of explants. To obtain virus-free regenerating plants, it is advisable to use apical meristems, callus tissue − leaf blades, active regeneration − microshoots. Stable regeneration system, its type, multiplication factor of Salicaceae plants are genetically determined. For the introduction of plants in vitro, active proliferation, rooting, microclonal propagation, it is advisable to use nutrient media according to WPM (McCown & Lloyd, 1981) and MS (Murashige & Skoog, 1962). For regeneration of plants by direct morphogenesis and activation of growth of existing meristems of an explant to apply the environment with cytokinins (BAP (6-benzylaminopurine), kinetin or 2-isopentenyladenine (2-ip), for rooting − with auxins NAA (α-naphthylacetic), IBA (3-indolylbutyric acid) and IAA (β-indolyl-3-acetic acid). Further research is aimed at optimizing the propagation protocols of Salicaceae plants in vitro.
