“…Penurunan disebabkan oleh rendahnya nilai keragaman genetik serta tingginya tingkat inbreeding pada populasi benih. Ariyanto et al (2018) menunjukkan bahwa tingkat keragaman genetik ikan mas yang berkembang di masyarakat sangat rendah, dengan nilai heterozigositas berkisar antara 0,08 hingga 0,20. Tingkat inbreeding pada populasi ikan mas memiliki nilai relatif tinggi, berkisar antara 0,79 hingga 0,91 (Ariyanto et al, 2019).…”

“…Sebagai populasi founder digunakan lima strain ikan mas yang dominan dibudidaya di masyarakat, yakni Majalaya (Mj), Rajadanu (Rj), Wildan (Wd), Sutisna (St) dan Sinyonya (Sy). Hasil penelitian Ariyanto et al (2018) menunjukkan bahwa lima strain ikan mas tersebut mempunyai jarak genetik cukup jauh, berkisar antara 0,42 hingga 0,58. Jarak genetik merupakan faktor penting dalam kegiatan persilangan dimana semakin jauh jarak genetik antara dua strain yang berbeda akan memperbesar sifat heterosis atau hybrid vigour yang diperoleh.…”

“…Perbedaan nilai heterosis ini diduga terkait dengan jarak genetik antar tetua pada masing-masing kombinasi hibrida tersebut. Ariyanto et al (2018) melaporkan bahwa jarak genetik antara strain Majalaya dengan Sutisna sebesar 0,582 sedangkan jarak genetik antara strain Sutisna dan Rajadanu sebesar 0,489. Jarak genetik yang lebih jauh antara strain Majalaya dengan Sutisna tersebut menghasilkan nilai heterosis yang lebih besar dibandingkan hibrida antara strain Sutisna dengan Rajadanu yang mempunyai jarak genetik lebih dekat.…”

Dalam rangka memperbaiki kualitas benih ikan mas, telah dilakukan kegiatan persilangan (hibridisasi) dua arah antar lima strain ikan mas, yaitu Majalaya (Mj), Rajadanu (Rj), Sutisna (St), Wildan (Wd) dan Sinyonya (Sy). Dari 25 populasi hasil persilangan, tiga kombinasi persilangan, yaitu St f >< Rj m (St x RJ), Mj f >< St m (Mj x St) dan St f >< Sy m (St x Sy) mempunyai nilai heterosis tertinggi pada karakter panjang dan bobot. Penelitian ini bertujuan mengevaluasi keragaan ketiga populasi hibrida tersebut untuk menentukan ikan mas hibrida terbaik sebagai kandidat strain unggul baru. Evaluasi keragaan populasi ikan mas hibrida dilakukan melalui dua pendekatan, yaitu karakter fenotipik menggunakan uji pertumbuhan dan komposisi warna tubuh serta karakter genotipik menggunakan metode mikrosatelit. Hasil analisis fenotipik menunjukkan bahwa populasi hibrida St x Sy mempunyai laju pertumbuhan panjang dan bobot sebesar 1,03±0,06 %/hari dan 3,03±0,24 %/hari, berbeda nyata dengan populasi hibrida St x Rj sebesar 0,92±0,04 %/hari dan 2,65±0,06 %/hari. Keragaan populasi hibrida St x Sy tersebut tidak berbeda nyata dengan populasi hibrida Mj x St yang mempunyai laju pertumbuhan panjang dan bobot sebesar 0,98±0,03 %/hari dan 2,78±0,08 %/hari. Namun demikian, berdasarkan analisis komposisi warna populasi hibrida Mj x St mempunyai warna tubuh yang seragam sehingga lebih diterima oleh konsumen. Hasil analisis genotipik menunjukkan bahwa ketiga populasi hibrida mempunyai kulitas genetik tidak berbeda nyata. Kualitas genetik yang diindikasikan dengan nilai heterozigositas, polimorfisme dan indeks fiksasi ketiga populasi hibrida, masing-masing berkisar antara 0,21 – 0,22; 0,86 – 0,88 dan 0,75 – 0,8. In order to improve the quality of common carp, hybridization program was carried out through diallel crosses between five common carp strains, namely Majalaya (Mj), Rajadanu (Rj), Sutisna (St), Wildan (Wd) and Sinyonya (Sy). Of the 25 populations obtained from the crosses, the hybrid of St f >< Rj m (St x RJ), f >< St m (Mj x St) and St f >< Sy m (St x Sy) had the highest heterosis of the body length and weight. This study aims to evaluate the performance of these three hybrid populations to determine the best population as a candidate for a new superior strain for common carp culture. Evaluation of the hybrid population was carried out through two approaches. The first is phenotypic characters using growth rate and body color composition tests and the second is genotypic characters using microsatellite methods. The result of the phenotypic analysis showed that the St x Sy population had a growth rate of length and weight of 1.03±0.06%/day and 3.03±0.24%/day, significantly different from that of the St x Rj population of 0.92±0.04%/day and 2.65±0.06%/day. The performance of the St x Sy population was not significantly different from the Mj x St population which had a growth rate of length and weight of 0.98±0.03%/day and 2.78±0.08%/day. However, based on the body color composition, population of Mj x St has a uniform color so that it is more acceptable to both of farmers and consumers. Genotypic analysis result showed that the three hybrid populations had no significantly different in genetic quality. The genetic quality indicated by the heterozygosity, polymorphism and fixation index of the three hybrid populations ranged from 0.21 to 0.22; 0.86 – 0.88 and 0.75 – 0.8.

Benih ikan mas telah mengalami penurunan kualitas genetik yang menyebabkan penurunan performa fenotipik di lingkungan budidaya. Salah satu upaya perbaikan genetik adalah melalui pembentukan populasi sintetis yang merupakan penggabungan potensi genetik beberapa populasi plasma nutfah ikan mas. Penelitian ini bertujuan membentuk dan mengevaluasi performa genotipik dan fenotipik populasi sintetis ikan mas, yang merupakan penggabungan dari strain Rajadanu, Majalaya, Sutisna, Wildan, dan Sinyonya. Performa genotipik dievaluasi menggunakan metode mikrosatelit DNA, sedangkan performa fenotipik dievaluasi menggunakan analisis biometrik terkait kegiatan budidaya. Hasil penelitian menunjukkan bahwa nilai keragaman genetik populasi sintetis lebih tinggi 55,0%-287,5% dengan tingkat inbreeding 40,0%-77,14% lebih rendah dibanding populasi-populasi pembentuknya. Hal ini berdampak terhadap performa fenotipik populasi sintetis yang lebih baik, diindikasikan dengan peningkatan panjang, bobot akhir, dan tingkat produktivitas, masing-masing sebesar 2,5%-20,6%; 9,4%-61,8%; dan 18,2%-66,0% lebih baik dibanding populasi-populasi pembentuknya. Peningkatan kualitas genetik dan performa fenotipik populasi sintetis ini memberikan peluang untuk memperbaiki kualitas benih ikan mas pada kegiatan budidaya.Common carp in Indonesia has experienced a decline in genetic quality. The progressive decline leads to a significant decrease in carp performance in the farming environment. One of the efforts to genetically improve carp growth performance is through developing synthetic carp populations, which is a blend of the genetic potentials from several germplasm populations. This study aimed to form and evaluate the performance of genotypic and phenotypic of synthetic populations of common carp, blended from five strains of common carp, i.e., Rajadanu, Majalaya, Sutisna, Wildan, and Sinyonya. The genotypic performance was evaluated using the DNA microsatellite method. The phenotypic performance was assessed using biometric analysis, especially in terms of culture performance. The results showed that the genotypic performance of the synthetic populations of common carp was better than that of the founder strains. This performance was indicated by higher genetic diversity values, about 55.0%-287.5% and lower levels of inbreeding, about 40.0%-77.1%, compared with their founder populations. Phenotypic performance of the synthetic populations is also better than their founder populations, indicated by higher body length, weight, and productivity, about 2.5%-20.6%, 9.4%-61.8%, and 18.2%-66.0%, respectively. The improvement on genetic quality and phenotypic performance of the synthetic population provide opportunities to improve the quality of common carp fry in aquaculture activity.

One of the effects of a decrease in the genetic quality of common carp is a decrease in resistance to disease. Establishing a synthetic population, blended from 5 strains, namely Rajadanu, Majalaya, Sutisna, Wildan, and Sinyonya, is expected to increase the disease resistance in the Indonesian common carp population. This study aims to evaluate the resistance of this synthetic population to Koi Herpesvirus (KHV) disease. The three common carp strains, Majalaya carp, Subang carp, and Cangkringan carp, were challenged with a cohabitation approach compared to the synthetic population. The water temperature was adjusted to the optimum condition for KHV development, which ranged from 20 – 22 °C. The result showed that KHV infection started on day three and peaked on days 6 to 10 after cohabitation. At the end of the challenge test, the survival rate of the synthetic population was 62.0 %, significantly higher than other strains (P<0.05), which ranged from 20.0 to 26.7 % of the constituent populations. The results of this challenge test indicated that the synthetic population of common carp had better resistance to KHV infection than other strains of common carp cultured by farmers.
