Peanut (Arachis hypogea) is a typical plant species of tropical regions that has high economic value. The plantation is widely spread over many areas and the production is being pushed to meet the increasing demand. Peanut breeding program is aimed to improve genetic quality, mainly with resepct of production and thus information on genetic diversity is necessary as a basis for consideration in breeding, management and sustainable utilization. One approach to analyse genetic diversity of peanut is by using molecular markers. Random Amplified Polymorphic DNA (RAPD) is a widely used molecular marker for genetic diversity analysis. Therefore, the aim of this study was to assess genetic diversity of peanut cultivars, i.e. Jerapah, Kancil, and Hypoma 2, based on RAPD markers. The study was conducted in a survey method, in which three individuals of each cultivar were analyzed using PCR-RAPD technique employing twelve primers, i.e. OPA-1, OPA-2, OPA-9, OPA-13, OPB-2, OPB-3, OPB-4, OPB-5, OPB-7, OPB-11, OPB-12 and OPJ-07. Data analysis based on morphological data is also included. Molecular analysis revealed that only 7.55% polymorphic band was obtained, while most of the bands were monomorphic, indicating very low variation among the cultivars. The phenogram that constructed based on literature showed that Kancil was closer to Jerapah cultivar, while RAPD-based dendogram showed that Hypoma 2 was closer to Kancil cultivar.

The genetic diversity and the relatedness among thirty-one germplasm lines of yellow sarson collected from eastern UP were evaluated using morphological characters and Random Amplified Polymorphic DNA (RAPD) markers. Molecular parameters, viz. A total number of bands, average polymorphic band, average percent polymorphism, average polymorphic information content (PIC), Jaccard’s similarity coefficient, Principal Coordinate Analysis (PCA) and dendrogram generated using RAPD markers. A total of 148 different polymorphic amplification products were obtained using 10 selected decamer primers. The Jaccard similarity coefficient ranged from 0.557-0.899. Maximum polymorphism detected was 100 %.The range of amplification was from 190bp to 9 kb. Some unique bands were also reported with different primers that can be used for the identification of particular accession. PYSC-11-11 and PYSC-11-36 genotypes showed a maximum number of unique loci of different size. 31 germplasm lines grouped into two major clusters I and II based on RAPD profiling. Morphological characterization was done on the basis of leaf, petal and beak characteristics. The similarity value among the germplasm lines ranged from 0.222 to 1.000 using morphological descriptors. The dendrogram generated grouped the germplasm accession into two major groups at 44% similarity value. The cluster analysis was comparable up to some extent with Principal Coordinate Analysis (PCA) of two and three-dimensional plots. The variability revealed by morphological and molecular profile were found to be non-comparable. This study indicated the presence of high genetic diversity among collected yellow sarson germplasm, which could be used for developing for breeding and germplasm management purposes.

Giant gouramy, Osphronemus gouramy Lac. is a popular fish species in Indonesia, especially in Java and Sumatera as this freshwater fish species has a high economic value of stable price. Fish farmers in Bogor divide giant gouramy into six strains based on egg productivity, growth rate, and maximum weight of the adult. They are soang, jepang, blue saphire, paris, bastar, and porselin. These various strains lead to the need of study on the genetic relationship among them, which can be performed by the use of RAPD (Random Amplified Polymorphic DNA) marker. This study aims to determine primers producing consistent and polymorphic RAPD markers, determine specific RAPD markers, and know the genetic relationship among several giant gouramy strains. The strains used in this study are soang, jepang, and blue saphire. Survey method was applied employing purposive random sampling technique. Total genomic DNA was isolated using Genjettm genomic DNA purification kit (Fermentas), which was then used as template to amplify RAPD markers with primers OPA-07, OPA-09, OPA-11, OPA-20, OPAH-01, OPAH-08, OPAH-09, and OPAC-14. The variables examined were patterns and numbers of specific DNA fragments as the PCR amplification products. Selected primers were determined descriptively on the basis of specific DNA bands appearing on the agarose gel. Genetic diversity was predetermined by changing qualitative band pattern into quantitative binnary data. Genetic relationship was analyzed using cladistic method with PAUP software. The results showed that only five of the eight primers produce consistent and polymorphic RAPD markers, i.e. OPA-11, OPA-20, OPAH-1, OPAH-8, and OPAH-9. Specific RAPD markers which can be used to distinguish several gouramy strains are those amplified with OPA-20 of 786 bp, OPA-20 of 1,176 bp, OPAH-8 of 1,000 bp and OPAC-14 of 1,607 bp. Nervertheless, it was found that RAPD markers cannot be used to clearly determine genetic relationship among gouramy strains.

Azadirachta indica A. Juss (Apocynaceae) is a large tree of the lowland tropical rain forest of Southeast Asia that occurs in Thailand, the Malay Peninsula, on the island of Java (East Java) and Lesser Sunda Islands. Its economic value was in its wood (timber), and as medicinal plant. The information on genetic diversity of the species is very limited. Hence studies were initiated and genetic diversity estimated using RAPD markers in 27 accessions of A.indica procured from three geographical regions of TN Baluran and Balai Litbang Kehutanan. Seven selected Operon primers (10 mer) generated a total of 133 consistent amplification products ranging from 132 bp to 5.6 Kb. The cluster analysis separated the 27 individuals into 2 clusters. The range of genetic dissimilarityvalue among samples was from 0.07 to 0.33, while genetic distance among populations was from 0.04 to 0.10. These values showed that A. indica from TN Baluran was not genetically diverse population. Key words: Azadirachta indica, genetic diversity, RAPD

Ptychobothridean genera like Senga and Circumoncobothrium are the common parasites of fresh water fishes. The genotypic study of these parasites was taken by RAPD. The RAPD profile of these two parasites were not similar to each other as depicted by the band pattern in picture. These results suggest the presence of inter-specific polymorphism among cestode parasites of two different genera for RAPD analysis. The present study demonstrated that genetic differentiation of cestode parasites could be accomplished on the basis of genomic variation with polymorphic band pattern using RAPD. All the detected bands (PCR product) were polymorphic and band size ranged from 500-5000 bp in length. The RAPD of profiles using GBO-31, GBO-32, GBO-33, GBO-34, GBO-35 and GBO-36. Primers were able to characterize inter-specific polymorphism among the two genus ( Senga and Circumoncobothrium ). Genetic analysis suggests that Senga and Circumoncobothrium show genetic diversity with respect to RAPD patterns using all the six primers used for the present study. The genetic distance between the analyzed genuses ranged from 0.14 to 0.80. The differentiation of the two parasites on the basis of genetic markers could greatly facilitate study on the biology of these parasites.

Random amplified polymorphic DNA (RAPD) markers were used to assess genetic diversity in Bambara groundnut (Vigna subterranea L.) germplasm using 25 African accessions from the collection in the International Institute for Tropical Agriculture, Ibadan, Nigeria. Fifty random decamer primers were screened to assess their ability to detect polymorphism in bambara; 17 of them were selected for this study. Considerable genetic diversity was found among the V. subterranea accessions studied. The relationships among the 25 accessions were studied by cluster analysis. The dendrograms showed two main groups of accessions mainly along the lines of their geographic origin. It is concluded that RAPD can be used for germplasm classification in bambara groundnut and hence for improving this crop.Key words: germplasm, PCR, RAPD, Vigna subterranea.

Camellia sinensis is a beverage tree crop native to Southeast Asia and introductions have been made into several nonindigenous countries. No systematic assessment of genetic variability in tea has been done anywhere. In this study, random amplified polymorphic DNA (RAPD) analysis was used to estimate genetic diversity and taxonomic relationships in 38 clones belonging to the three tea varieties, assamica, sinensis, and assamica ssp. lasiocalyx. Extensive genetic variability was detected between species, which was partitioned into between and within population components. Seventy percent of the variation was detected within populations. Analyses based on band sharing separated the three populations in a manner consistent with both the present taxonomy of tea and with the known pedigrees of some clones. RAPD analysis also discriminated all of the 38 commercial clones, even those which cannot be distinguished on the basis of morphological and phenotypic traits.Key words: genetic diversity, RAPDs, Camellia sinensis.

The increasing demand for raw material for multiple uses of forest products and by-products has attracted the interest for fast growing species, such as the Australian Cedar (Toona ciliata), which presents high productive and economic potential. The present work aimed at estimating genetic diversity by DNA markers and morphological traits supported for the mixed models. The following traits were measured and genotypes were sampled randomly in different areas: diameter at breast height, height, cylindrical volume, diameter, distance between nodes and crown diameter. Twelve RAPD primers were used and generated a total of 91 marks, 82 of which were polymorphic. The high percentage of polymorphic markers, 90.10%, demonstrated that discrimination in this species is efficient, but it yet little studied, for this case we can find the extent of the genetic basis for the application of technical improvement. The assessment of genetic diversity by the UPGMA method using the binary and morphological data provided the expression of genetic dissimilarities among the accessions evaluated, optimizing the perception of this divergence. The use of mixed models was efficient to assess combined genetic diversity to optimize the selection of genotypes with divergent genetic values for diameter at breast height.
