Morphometrics and genetic diversity of Tegal, Magelang and their crossbred ducks based on Cytochrome b gene

Abstract

This experiment was conducted to study the morphometric and genetic diversity of Tegal, Magelang, and their crossbred ducks. Each ten female about twenty weeks old ducks from Tegal, Magelang, Gallang, and Maggal ducks, respectively, were used as the group materialss. The body weight, chest circumference, body length, shank length, neck length, and pubis width were recorded and tested by analysis of variance of one way classification as the morphometric characteristics. Polymorphism of cytochrome b (cyt b) gene on mitochondrial DNA (mtDNA) was analyzed by Polymerase Chain Reaction-Restriction Fragment Length Polymorphism (PCR-RFLP). Genetic distance was analyzed based on value of heterozygosity, whereas the phylogeny tree was reconstructed using MEGA6 software. The results showed there were highly significant difference (P<0.01) on body weight, chest circumference, body length, and neck length between population, while shank and pubis width were not significant different. The genetic distance between Gallang and Maggal ducks (0.206) was higher than Tegal and Magelang ducks (0.169). It is concluded that the reciprocal crosses increased the morphometric and genetic diversity of Indonesian local duck population.

Morphology, Morphometry, Growth Performance and Carcass Characteristics of Pekin, Nageswari and Their F1 Crossbred Ducks under Intensive Management

“…All of the previous studies reported that the black phenotype in domestic ducks is caused by a gain-of-function mutation in the extended black (E) locus which harbored by the MC1R gene.All of the morphometric traits of this study varied significantly among the genotypes except shank and wing length in both males and females. Similar to our findings,Henrik et al (2018) reported that reciprocal crosses increased the morphometric measurements in Indonesian local duck populations.…”

The phenotype characteristics and decline population of Sawang duck in Sawang Village, Karimun Regency, Riau Islands Province

“…It forms their characteristics which can be passed on to subsequent offspring. Genetic and morphometric diversity are important for breeding management and increasing productivity of these local ducks (Henrik, Purwantini and Ismoyowati, 2018), design of animal breeding programs, genetic mapping, and molecular markers (Yakubu, Kaankuka and Ugbo, 2011;Rusdin et al, 2020). One of the local duck genetic resources possessed by the Riau Islands Province is Sawang duck (Setioko, Prasetyo and Sinurat.…”

Keragaman Fenotipe Kualitatif dan Kuantitatif Itik Sikumbang Jonti sebagai Plasma Nutfah di Sumatera Barat

“…Selain itu, itik Sikumbang Jonti betina memiliki panjang leher terpanjang dibandingkan itik Pitalah dan itik (Maharani et al 2019). Selain itu, itik Sikumbang Jonti memiliki bobot badan yang lebih rendah dari itik Magelang (Henrik, Purwantini, and Ismoyowati, 2018) dan itik Alabio (Suryana et al 2014), tetapi lebih tinggi dari itik Tegal. Itik Sikumbang Jonti memiliki ukuran lebar pelvis yang lebih kecil dibandingkan itik Magelang dan itik Tegal (Henrik, Purwantini, and Ismoyowati, 2018).…”
