Abstract: Over the past two decades, the advances in the next generation sequencing (NGS) platforms have led to the identification of numerous genes/QTLs at high-resolution for their potential use in crop improvement. The genomic resources generated through these high-throughput sequencing techniques have been efficiently used in screening of particular gene of interest particularly for numerous types of plant stresses and quality traits. Subsequently, the identified-markers linked to a particular trait have been used in marker-assisted backcross breeding (MABB) activities. Besides, these markers are also being used to catalogue the food crops for detection of adulteration to improve the quality of food. With the advancement of technologies, the genomic resources are originating with new markers; however, to use these markers efficiently in crop breeding, high-throughput techniques (HTT) such as multiplex PCR and capillary electrophoresis (CE) can be exploited. Robustness, ease of operation, good reproducibility and low cost are the main advantages of multiplex PCR and CE. The CE is capable of separating and characterizing proteins with simplicity, speed and small sample requirements. Keeping in view the availability of vast data generated through NGS techniques and development of numerous markers, there is a need to use these resources efficiently in crop improvement programmes. In summary, this review describes the use of molecular markers in the screening of resistance genes in breeding programmes and detection of adulterations in food crops using high-throughput techniques.

Aquaculture Production

The high yields obtained in agriculture rely heavily on the use of domesticated and genetically improved breeds and varieties. Until quite recently this has not been the case for most farmed aquaculture species that, in the genetic sense, are still much closer to the wild state than are the major terrestrial animals and food crops. Less than 10 % of the total world aquaculture production is based on improved strains. Due to a growing human population and a decline in production from capture fisheries, there is therefore a great disparity between the need for increased aquaculture production and the genetic quality of the strains available to meet that need. Moreover, full benefits of investments in management improvements (feed and feeding practices, control of diseases, etc.) can only be obtained through the use of genetically improved animals.

SUMMARYFood legumes are the main source of dietary protein for a large part of the world's population, and also play an important role in maintaining soil fertility through nitrogen fixation. However, legume yields and production are often limited by large genotype×environment (G×E) interactions that influence the expression of agronomically important, complex quantitative traits. Consequently, genetic improvement has been slower than expected. Molecular marker technology enables genetic dissection of such complex traits, allowing breeders to identify genomic regions on the chromosome that have main effects or interactive effects. A number of genomic resources have been developed in several legume species during the last two decades, and provide a platform for exploiting marker technology. The present paper reviews the available genomic resources in food legumes: linkage maps, high-throughput sequencing technologies, expression sequence tag (EST) databases, genome sequences, DNA chips, targeting induced local lesions in genomes (TILLING), bacterial artificial chromosome (BAC) libraries and others. It also describes how these resources are being used to tag and map genes/quantitative trait loci (QTLs) for domesticated and other agronomically important traits. This information is important to genetic improvement efforts aiming at improving food and nutrition security worldwide.

<p><strong>Abstract</strong></p><p>West Kalimantan is are area of tropical rain forest with high rainfall more than 3600 millimeter per year. Potential areas for food crops are 11,6 million ha, only 1,03 million are effective for agriculture activity and 255.339 ha for intensification based on 57.5-73.8% of which used high yielding varieties and less than 42% used local variety. The varieties planted by the native have specific use and maintained from generation to generation. Many of local cultivar were planted by Dayak tribe in the deepest of West Kalimantan. Exploration on Food Crops was conducted to collect germplasm of paddy and palawija which were conserved and evaluated, and would be used as the source of gene in rice genetic improvement. The result of this exploration from the 7 district were 191 accessions germplasm of the food crops which were 129 accessions paddy consists of 69 accessions of lowland rice, 31 accessions of upland rice, and 29 accessions of tidal swamp rice. About 62 accessions palawija germplasm consist of 3 accessions of corns, 11 accessions of cassava, 17 accessions of sweetpotato, 6 accessions of peanut, 1 accessions of mungbean, 6 accessions of jam, 15 accessions of taro, 2 accessions of cowpea, and 1 accessions of jewawut.</p><p><strong>Abstrak</strong></p><p>Kalimantan Barat mempunyai iklim hutan tropis dengan curah hujan di atas 3600 mm. Dari 11,6 juta ha lahan yang berpotensi untuk tanaman pangan, baru dimanfaatkan 1,03 juta ha. Dari seluas 235.395 ha areal intensifikasi padi, 58,3% di antaranya telah ditanami varietas unggul dan sisanya varietas lokal. Varietas-varietas lokal yang ditanam penduduk mempunyai karakteristik spesifik, merupakan kebanggaan warga yang turun temurun dipertahankan oleh sukunya. Masih banyak jumlahnya kultivar lokal yang ditanam oleh penduduk suku-suku dayak di pedalaman Kalimantan Barat. Eksplorasi tanaman pangan bertujuan untuk mengumpulkan plasma nutfah padi dan palawija untuk dikonservasi, diberdayakan, dan dimanfaatkan sebagai sumber gen, untuk perbaikan sifat ketahanan dan toleransi terhadap hama dan penyakit dalam program pemuliaan tanaman. Hasil eksplorasi dari 7 kabupaten telah terkumpul sejumlah 191 aksesi plasma nutfah tanaman pangan, yaitu sebanyak 129 aksesi padi terdiri dari 69 aksesi padi sawah, 31 aksesi padi ladang dan 29 aksesi padi pasang surut. Sebanyak 62 plasma nutfah palawija terdiri dari 3 aksesi jagung, 11 aksesi ubi kayu, 17 aksesi ubi jalar, 6 aksesi kacang tanah, 1 aksesi kacang hijau, 6 aksesi ubi kelapa/krimbang, 15 aksesi talas, 2 aksesi kacang tunggak dan 1 aksesi jewawut.</p>
