<p>The objective of this study was to evaluate the genetic relationships among Wonosobo sheep (Dombos), Thin-Tailed sheep (DET) and Batur sheep (Dombat) through blood protein polymorphism analysis by using electrophoresis Polyacrylamid Gel Electrophoresis-Thin Layer Electrophoresis (PAGE-TLE). The blood of the 20 head of Dombos (Wonosobo regency), 20 head of DET (Semarang regency) and 20 head of Dombat (Banjarnegara regency) were used as materials. Six locus of blood plasma protein were observed, then the gene frequency, individual heterosigosity, average<br />heterosigosity and genetic distance among three breed were calculated. The results showed that the locus of pre-albumin (Pa), albumin (Alb), ceruloplasmin (Cp), transferrin (Tf), post-transferrin (P-tf) and amylase-I (Am-I), at DET, Dombos and Dombat were polymorphic (0,380-0,454). In conclusion, the DET and Dombat indicated the closer genetic relationship compared to DET-Dombos and Dombos-Dombat.<br />Key words: sheep, polymorphism, genetic relationship</p>

Semakin jauh jarak genetikantar tetua maka peluang dihasilkan kultivar baru dengan variabilitasgenetik yang luas akan menjadi semakin besar. Sebaliknya, persilanganantar tetua berkerabat dekat akan menghasilkan variabilitas yang sempit.Penelitian ini dilaksanakan pada bulan Mei 2007 di Kabupaten MinahasaUtara, Minahasa Selatan dan Bolaang Mongondow, Sulawesi Utara. Disetiap kabupaten ditetapkan tiga desa contoh pada ketinggian yangberbeda.

Genotype performance of Tambakan, Helostoma temminckii (Cuvier, 1829) from Sumatera, Java and Kalimantan Polulation using Random Amplified Polymorphic DNA (RAPD)        Tambakan, kissing gourami (Helostoma temminckii) is well known as a freshwater tropical  species from Southeast Asia. In Indonesia, tambakan is an important commodity. However, total production of tambakan tends to decrease. Therefore, domestication has urgently to be done to solve the problem of Tambakan population. Three different tambakan populations from Sumatera, Java and Kalimantan were observed to find good genetic resources for culture activity. This study aimed to investigate the genetic variation of tambakan especially from West Java, Jambi, and South Kalimantan province using RAPD. The result showed that the highest polymorphism and heterozygosity was from South Kalimantan population among others. The three population observed had the fragment size ranged from 100- 2000 bp. The highest genetic distance was between Sumatera and Kalimantan (0,2877), while the lowest was between Kalimantan and Java (0,1961). Key words: Helostoma temminckii, genetic, heterozigosity, genetic relationship ABSTRAK        Ikan tambakan (Helostoma temminckii) adalah salah satu jenis ikan air tawar yang berasal dari wilayah tropis, tepatnya Asia Tenggara. Di Indonesia ikan tambakan merupakan salah satu ikan komoditas penting. Saat ini, jumlah produksi ikan tambakan cenderung menurun. Sehingga domestikasi sangat diperlukan untuk mengatasi masalah peneurunan populasi tambakan Tiga populasi ikan tambakan dari Sumatera, Jawa dan Kalimantan diobeservasi untuk mendapatkan sumber genetic terbaik yang dapat digunakan untuk kegiatan budidaya.. Penelitian ini bertujuan untuk mengidentifikasi keragaman genetika populasi ikan tambakan Jambi, Jawa Barat dan Kalimantan Selatan menggunakan metode RAPD. Hasil menunjukkan bahwa polimorfisme dan heterosigositas tertinggi terdapat pada populasi ikan tambakan Kalimantan Selatan jika dibandingkan dengan populasi ikan tambakan lainnya.

and is a cross-pollinator, so information about the genetic relationship between the accessions in germplasm collections is very important for selecting the prospective parent in crossbreeding. This research aims to determine the phylogenetic relationship of 24 Saccharum complex accessions and to verify the grouping of accessions using 37 morphological and three microsatellite molecular markers. Interpretation of morphological and molecular data was obtained from the analysis using the NTYSYpc-2.02i program. The results show that within the 24 accessions analyzed using morphological markers, some accessions did not cluster as the classification at the conservation time. This difference is due to the morphological markers, descriptions of characters that do not appear are considered as the same variables though in different morphological characters, so this increases the value of genetic similarity among accessions analyzed. In contrast, the grouping of molecular markers shows that each accession was grouped according to the classification at the conservation time. These accessions had a low genetic similarity of 0.20 with a broad genetic distance of 0.80. This broad genetic distance indicates that the twenty-four accessions have a distant genetic relationship with one another, so that the genetic diversity of these accessions is relatively high. The high genetic diversity in germplasm collections improves its potential as a crossing parent to obtain a high heterosis effect.

Genetic relationship can be a useful predictor of the relative performance of hybrid combinations for a hybrid breeding program resulting in reduced time and cost of hybrid testing. Genetic relationships of 112 wheat (Triticum aestivum L. em. Thell.) lines were estimated using 41 DNA clones hybridizing to 273 DNA fragments and by calculating coefficient of parentage (COP). Heterosis was estimated for 722 hybrids grown in multiple locations, with 189 being tested in more than 1 year. The average RFLP (restriction fragment length polymorphism) based genetic distance index (DI) was 0.35. Midparent heterosis for grain yield ranged from −20 to 57% and high-parent heterosis from −22 to 47%. The correlation between RFLP-based estimates of genetic distance and COP was nonsignificant (−0.33). Coefficient of parentage was significantly correlated with heterosis for all traits in 1991 but not in other years. Genetic distance based on RFLPs scored in this study was not correlated with heterosis in any of the years tested. Further refinement of gene pools and new prediction methods will be required to facilitate the exploitation of genetic variability for hybrid wheat improvement. Key words : wheat, heterosis, genetic distance.

Nondenaturating disc gel electrophoresis revealed that 99Mo was incorporated into the nitrate reductase of Azospirillum brasilense grown in the absence but not in the presence of tungstate. Under denitrifying conditions, A. brasilense grown in tungsten-free medium steadily accumulated 99Mo for 12 h. In contrast, Paracoccus denitrificans grown under the same conditions ceased uptake after 1 h. However, both bacteria were incapable of accumulating significant amounts of 99Mo in media containing 10 mM tungstate, even though nitrate was reduced by A. brasilense. Aerobically grown A. brasilense cells transported 99Mo more efficiently than anaerobically grown cells. Key words: Azospirillum brasilense, tungsten, molybdenum incorporation, nitrate reduction.

Hibiscus tiliaceus L. (Malvaceae) is a pantropical coastal tree that extends to the tidal zone. In this study, the retrotransposon sequence-specific amplified polymorphism (SSAP) technique was used in order to understand the genetic variation between four population pairs of H. tiliaceus from repeated estuarine and inland habitat contrasts in China. The estuarine populations were consistently more genetic variable compared with the inland ones, which may be attributed to extensive gene flow via water-drifted seeds and/or retrotransposon activation in stressful estuarine environments. An AMOVA revealed that 8.9% of the genetic variance could be explained by the habitat divergence within site, as compared with only 4.9% to geographical isolation between sites, which indicates significant habitat differentiation between the estuarine and inland populations. The estuarine populations were less differentiated (ΦST = 0.115) than the inland (ΦST = 0.152) implying frequent gene interchange in the former. Accordingly, the principal coordinate analysis of genetic distance between individuals revealed that genetic relationships are not fully consistent with the geographic association. These results suggest that despite substantial gene flow via sea-drifted seeds, habitat-related divergent selection could be one of the primary mechanisms that drive habitat differentiation in H. tiliaceus at a local ecological scale.
