Abstract. Tanjung A, Saragih HTSSG, Trijoko, Soenarwan HP, Widianto S, Mahardhika IWS, Daryono BS. 2019. Polymorphism of myostatin gene and its association with body weight traits in a hybrid of GAMA chicken (Gallus gallus domesticus Linn. 1758). Biodiversitas 20: 3207-3212. An experiment was conducted to detect SNP of the myostatin gene and its association with the body weight of hybrid chicken crossbreed from F1 Kamper and BC1 Broiler. Four F1 Kamper hens were crossbred with BC1 Broiler rooster. Day old chick (DOC) hatched were maintained for 49 days with body weight measurement every seven days. The blood samples from 49 days old chicken were taken for DNA isolation by Chelex 5% method and then amplification of the myostatin gene. PCR products were sequenced, and sequence alignment was performed using Clustal Omega to obtain SNP. The SNP obtained was analyzed by the Pearson correlation test with the body weight of forty nine-days-old chickens. The body weight of the hybrid chicken is higher than of Pelung chicken but lower than the Broiler. There are 7 SNPs in myostatin gene exons included 2 Adenine insertions, 1 Guanine deletion, and four substitutions (C2244G, G2283A, T4842G, G7378T) that yield nine haplotypes. Six haplotypes had different protein sequences with Myostatin protein, while three haplotypes were identical to Myostatin protein. The correlation analysis showed that there was a strong positive correlation (r = 0.736) between normal Myostatin protein and mutant to chicken body weight at 49-days-old. Adenine insertion to nucleotide 2099-2100 of myostatin gene had a very strong positive correlation (r = 0.800) to 49-days-old chicken body weight, although T4842G substitution had a strong negative relationship (r = -0.773) to 49-days-old chicken body weight. Adenine insertion to nucleotide 2099-2100 of myostatin gene could be a genetic marker of heavier body weight of the hybrid chicken.

Abstract. Husnudin UB, Daryono BS, Purnomo. 2019. Genetic variability of Indonesian Eggplant (Solanum melongena) based on ISSR markers. Biodiversitas 20: 3049-3055. Eggplant (Solanum melongena L.) is one of important vegetable in Indonesia and this country has a variety of eggplant germplasm, whereas molecular data of Indonesian eggplant is limited. This study describes an analysis of genetic variation based on ISSR markers to determine the diversity and phenetic relationship of Indonesian eggplants. 23 samples were collected from the Indonesian Center for Agricultural Biotechnology Research and Development (ICABIOGRAD) and some commercial cultivars. Data were analyzed by ISSR analysis using UBC 809, UBC 880, UBC 888, UBC 892 and UBC 895 primers. Similarity index was counted by Jaccard Coefficient formula based on molecular scoring. Cluster analysis was conducted by Unweighted Pair Group Methods using Arithmetic averages (UPGMA) method to create a dendrogram with Multivariate Statistical Program (MVSP) v.3.1 software. The results showed that ISSR markers were effective in the estimation of the genetic variability of eggplant accessions characterized by different level of polymorphism. Five ISSR primers generated 40 polymorphic bands (64.5% of the total). The dendrogram divided 23 eggplant accessions into 2 main clusters and one accession ("terong jawa"/K18) located outside from the main cluster. Results suggested that all accessions were grouped randomly into some clusters not in accordance with the locations of sample collection.

Abstract. Sungkawati M, Hidayati L, Daryono BS, Purnomo. 2019. Phenetic analysis of Curcuma spp. in Yogyakarta, Indonesia based on morphological and anatomical characters. Biodiversitas 20: 2340-2347. Curcuma spp., also known as ginger (Zingiberaceae), has economic value in traditional medicine. However, its many morphological variations cause difficulties in identification and classification. Therefore, observation of its morphological and anatomical characteristics, and of the phenetic relationships between Curcuma species, is important. This research aims to determine the specific characteristics of Curcuma spp. and to examine its phenetic relationships based on morphological and anatomical characteristics. The research was conducted in July 2018-February 2019 in the Bantul, Gunungkidul, Sleman and Karanganyar regions. Observation of the anatomical characteristics was conducted on the leaves and rhizomes and the data analyzed according to descriptive and quantitative/numerical methods. Clustering analysis with the Gower General Similarity Coefficient and Principal Component Analysis (PCA) was performed to determine the role of each character in groupings. The results of the research found seven species from 23 OTUs observed (C. aeruginosa, C. domestica, C. manga and C. xanthorrhiza, each with four OTUs; C. soloensis and C. zedoaria, with three OTUs each; and C. heyneana with one OTU) and showed that specific morphological characteristics were found in the flesh color rhizome, pseudostem color and midrib color. Specific anatomical characteristics were evident in the secretion cell color and the presence of trichomes on the leaves and rhizomes. The dendrogram shows a 0.70 phenon line consisting of two groups, group A (C. soloensis and C. domestica) fused in a 0.760 similarity index, and group B (C. aeruginosa, C. mangga, C. heyneana, C. soloensis, C. xanthorrhiza and C. zedoaria) fused in a 0.654 similarity index, which means that C. soloensis and C. domestica have a close phenetic relationship. The 0.80 phenon line consisted of five groups: C. domestica, C. soloensis, C. xanthorrhiza, C. zedoaria-C. mangga-C. heyneana and C. aeruginosa.

Daryono BS, Mushlih M, Perdamaian ABI. 2021. Crowing sound and inbreeding coefficient analysis of Pelung chicken (Gallus gallus domesticus). Biodiversitas 22: 2451-2457. Pelung is one of the crowing-typed chickens from Indonesia. The bioacoustics characters of Indonesian crowing-typed chicken especially Pelung chicken were less documented. This study aimed to characterize crowing sound and to study the inbreeding coefficient of the Pelung chicken. In this study, crowing voice of 77 male Pelung chicken was recorded. Bioacoustics analyses of crowing voice were done using Adobe Audition CS5.5 and PRAAT 5.3.66 software. The results showed that chicken crowing consisted of front sound (first syllable), middle sound (second syllable) and end sound (third syllable). Each section of Pelung crowing had specific characteristics compared to other chicken breeds and varied among champions and nonchampions. Champion chicken had slowed and clear first and second syllable, sound energy was lower in first syllable then decrease at second syllable and has bitu gantung third syllable. Crowing duration and fundamental frequency (F0) of champion and non-champion were not statically different. The inbreeding coefficient reached 0.53 in several Pelung champions. Based on the research findings, bioacoustics software was applicable to assist the chicken show.
