<p>Superiority and Potential Development of Durio Germplasm in Central Kalimantan. Amik Krismawati. Indonesia is rich of genetic resources and biodiversity of Durio spp., but its development no so fastly as in Thailand. This is due to plant durio has not managed commercially and it grew hundred years and it origin from generative propagation, caused the durio plantation variety heterogen. To determine the performance and advantage of the diversity of genetic resources should be conducted observations of durio related species the characterization in each district centre. Observation and characterization of related species of durio e.i. Durio zibethinus M. (durian), Durio kutejensis H.B (papaken), Durio oxleyanus (kerantungan/taetungen), and Durio dulcis (layung) were conducted in four districts of Central Kalimantan from August 2004 to January 2005. Seasons fruity and yield of each species to variously among the durio and its related species. Differences among accesions were characterized by fruit type, fruit shape, fruit skin texture, fruit length, fruit skin colour, fruit flesh colour, and taste. The fruiting season and fruit production of each species also varied durio relatives.The result of characterization showed the related species of Durio are indigenous of Indonesia and potencially to development in the future.</p><p> </p><p><strong>Abstrak</strong></p><p>Indonesia kaya akan sumber plasma nutfah dan keragaman jenis durian (Durio spp.), namun pengembangannya tidak sepesat Thailand. Hal ini disebabkan tanaman durian belum dikelola secara komersial dan tanaman yang ada umumnya sudah berumur ratusan tahun yang berasal dari perbanyakan generatif sehingga tidak memberikan hasil yang optimal. Untuk mengetahui keunggulan dari keanekaragaman sumber daya genetik durian maka dilakukan observasi dan karakterisasi di beberapa lokasi di empat kabupaten di Kalimantan Tengah dari Agustus 2004 hingga Januari 2005. Kerabat durian yang diobservasi dan dikarakterisasi adalah durian (Durio zibethinus M.), papaken (Durio kutejensis H.B.), kerantungan/taetungen (Durio oxleyanus), dan layung (Durio dulcis). Hasil karakterisasi menunjukkan bahwa karakter buah antarspesies kerabat durian sangat bervariasi. Perbedaan di antara spesies tersebut terletak pada tipe buah, bentuk buah, tekstur kulit buah, panjang buah, warna kulit buah, warna dan rasa daging buah. Musim berbuah dan produksi masing-masing spesies kerabat durian juga bervariasi. Kerabat durian dari jenis Durio (Durio spp.) yang merupakan tanaman asli Indonesia berpotensi dikembangkan.</p>

AbstractUK agriculture is undergoing significant change with reduced subsidies for food production, increasing consumer demands for food safety and traceability, and environmental concerns including climate and demographic change. The International Treaty on Plant Genetic Resources for Food and Agriculture adopted by the United Nations Food and Agriculture Organisation supports the use of genetic resources for research and breeding. Mining genetic resources for useful genetic variation is perceived as a major benefit of genebanks. However, utilization by breeders may be constrained by poor characterization of genetic resources, a widening gap between improved and unimproved material, and the disruption of well- adapted genotypes during introgression. Breeders working with grasses and forage legumes for sustainable agriculture are fortunate in the wealth of genetic variation available both within the primary species of interest and among related species. New DNA technologies allow more targeted approaches to the use of these genetic resources. Possibilities for gene transfer between related species using conventional techniques expand the available gene pools while potential use of genetic transformation extend these even further.

Jambi Province has large peatlands (621,089 ha). Utilization of that land in agricultural sector will contribute in economic development of surrounding society. Tangkit and Paun Pineapple are plant genetic resource (PGR) that must be maintained and secured from extinction and erosion of genetic potential. This is because the real PGR continues to be utilized for the survival and welfare of the community. The research purpose was to know the morphological of PGR pineapple that have potential to grow, produce and adapt in peatland of Jambi Province. Survey method was used in this research and conducted in Tangkit Baru Village, Sungai Gelam District, Muaro Jambi Regency and Sungai Baung Village, Pengabuan District of Tanjung Jabung Barat Regency, Jambi Province in 2016 and 2017. The results showed that significant different were occurred between Tangkit and Paun pineapple in leaf morphology, flowers, fruit, harvesting age and production/ha. Production of Tangkit and Paun pineapple were 13.5 ton/ha and 9.1 - 13 ton/ha respectively. The leaves of Tangkit pineapple were prickly, meanwhile, Paun pineapple was not thorny; Fruit of Tangkit pineapple was round oval, and Paun pineapple cones-like with 3-4 times bigger in size than Tangkit pineapple (3.5 - 5 kg). Paun Pineapple can only grow in peatland with 3 m depth while on shallow peat fruit production is not optimal. Tangkit Pineapple grow and produce well on peatland with pH ≤ 5.0. Paun Pineapple also well adapted to low peatlands with elevation 0 - 30 m asl and soil pH 4.5 - 6.5.

Out of 78 germplasm of muskmelon (Cucumis melo L.), 67 germplasm (86%) survived against high salinity (13.82 ds/m) when screened at Benarpota, Satkhira, Khulna. These germplasm showed morphological variations in growth habit, leaf lobes, leaf pubescence, fruit shape, fruit ribs, fruit skin texture, flesh colour, flesh flavor, flesh texture, fruit splitting, fruit aroma, fruit size, seed coat colour, fruit skin colour at fully formed fruit and fruit skin colour at seed harvest maturity. The other qualitative characters, such as tendrils and flowering habit did not show morphological variations. Quantitative variations were observed in leaf length, leaf width, days to staminate flowering, days to pistillate flowering, fruit length, fruit width, fruit weight, number of fruits per plant, flesh thickness, number of seeds per fruit, days to fruit harvest and 1000-seed weight. Among the germplasm, BD-2255 and BD-9159 had no splitting of fruits. Therefore, these two germplasm can be selected for this trait. The characters, such as number fruits per plant and fruit weight exhibited highest number of fruits per plant (21) and maximum fruit weight (6.25 kg). These two characters should also be considered for improvement of muskmelon. Highest CV (%) was found in number of fruits per plants (36.35) followed by fruit weight (33.86). Bangladesh J. Agril.

Abstract - Laser-Induced Breakdown Spectroscopy (LIBS) is one method of atomic emission spectroscopy using laser ablation as an energy source. This method is used to characterize the type of amethysts that originally come from Sukamara, Central Kalimantan. The result of amethyst characterization can be used as a reference for claiming the natural wealth of the amethyst. The amethyst samples are directly taken from the amethyst mining field in the District Gem Amethyst and consist of four color variations: white, black, yellow, and purple. These samples were analyzed by LIBS, using laser energy of 120 mJ, delay time detection of 2 μs and accumulation of 3, with and without cleaning. The purpose of this study is to determine emission spectra characteristics, contained elements, and physical characteristics of each amethyst sample. The spectra show that the amethyst samples contain some elements such as Al, Ca, K, Fe, Gd, Ba, Si, Be, H, O, N, Cl and Pu with various emission intensities. The value of emission intensity corresponds to concentration of element in the sample. Hence, the characteristics of the amethysts are based on their concentration value. The element with the highest concentration in all samples is Si, which is related to the chemical formula of SiO2. The element with the lowest concentration in all samples is Ca that is found in black and yellow amethysts. The emission intensity of Fe element can distinguish between white, purple, and yellow amethyst. If Fe emission intensity is very low, it indicates yellow sample. Thus, we may conclude that LIBS is a method that can be used to characterize the amethyst samples.Key words: amethyst, impurity, laser-induced, breakdown spectroscopy, characteristic, gemstones

The P genome of Agropyron cristatum Gaertn. contains many desirable genes that can be utilized as genetic resources to improve wheat. In this research, we used both the gametocidal chromosome 2Cc and the pairing homologous gene (Ph1b) mutant to induce structural aberrations and translocations between wheat and the 4P, 5P, and 6P genome chromosomes. By using the two approaches, a total of 19 wheat-A. cristatum translocations have been identified, in which 13 were induced by the Triticum aestivum cv. Chinese Spring (CS) ph1b mutant (CS ph1b) and six were induced by gametocidal chromosome 2Cc from Aegilops cylindrica Host. The wheat-4P, -5P and -6P A. cristatum translocations were characterized by in situ hybridization and by a set of conserved orthologous set (COS) molecular markers. The aberrations included centromeric translocations, terminal translocations, dicentric translocations, and deletions. The average induction frequency of chromosome structural aberrations was 10.9% using gametocidal 2Cc chromosome and 8.8% using ph1b mutant. The highest frequency obtained was for chromosome 4P using both approaches. All the wheat-A. cristatum translocation lines obtained were valuable for identifying A. cristatum chromosome 4P, 5P, and 6P related genes. In addition, these lines provided genetic resources and new germplasm accessions for the genetic improvement of wheat.
