Chinese pony populations; Genetic diversity; Genetic relationship; Microsatellite markers

China is one of the principal origins of ponies in the world. We made a comprehensive analysis of genetic diversity and population structure of Chinese ponies based on 174 animals of five indigenous Chinese pony breeds from five provinces using 13 microsatellite markers. One hundred and forty-four alleles were detected; the mean number of effective alleles among the pony breeds ranged ... more

Achillea species; Genetic diversity; ISSR; Marker; RAPD

Cultivation and preservation of yarrow has recently attracted wide attention due to its beneficial properties; however, genetic variation of Achillea species is still relatively unknown. We used RAPD and ISSR markers to assess genetic diversity in 16 accessions of yarrow belonging to two species native to Iran. Seven ISSR and nine RAPD primers generated 187 amplified fragments, ... more

Elymus sibiricus; Genetic diversity; Population structure; RAPDs

Genetic diversity of Elymus sibiricus (Poaceae) was examined in eight populations from the southeast Qinghai-Tibet Plateau. We detected 291 RAPD polymorphic loci in 93 samples. The percentage of polymorphic bands (PPB) was 79%. Genetic diversity (HE) was 0.264, effective number of alleles (NE) was 1.444, Shannon’s information ... more

Genetic diversity; Hemarthria compressa; Population structure; SRAP

Hemarthria compressa is one of the most important and widely utilized forage crops in south China, owing to its high forage yield and capability of adaptation to hot and humid conditions. We examined the population structure and genetic variation within and among 12 populations of H. compressa in south China using sequence-related amplified polymorphism (SRAP) markers. ... more

Climatic factors; Genetic diversity; Geographic information system; Random amplified polymorphic DNA; Stipa breviflora

Genetic diversity of Stipa breviflora populations in the Inner Mongolian grasslands of China and its possible correlation with climatic factors was examined using geographic information systems and random amplified polymorphism DNA analysis. A total of 308 bands were produced with 28 arbitrary decamer oligonucleotide. Three major findings were demonstrated. First, the genetic ... more

DNA fingerprinting; Genetic diversity; Olea europaea; RAPD

A total of 91 wild olive accessions and 31 olive cultivars growing in the Extremadura region of central-western Spain were analyzed using morphological traits and RAPD markers. We focused on three main and 16 minor Spanish olive cultivars that are recognized as native or local to the Extremadura region. The five arbitrary 10-mer primers tested on the olive cultivars gave 67 polymorphic ... more

Genetic characterization; Genetic diversity; Genetic structure; Genome comparisons

Genetic characterization among Red Junglefowl (GS, Gallus gallus spadiceus), Thai indigenous chicken (TIC, Gallus domesticus) and commercial lines has been widely used for studies of genealogical origin, genetic diversity, and effects of selection. We compared the efficiency of genetic characterization of chicken populations that had been under different intensities of ... more

Genetic diversity; Genetic structure; SSR

Nine microsatellite loci were isolated from the genome of Laodelphax striatellus (Homoptera: Delphacidae) by constructing (TC)6(AC)5 and (AG)6(AC)5 compound SSR-enriched libraries using suppression-PCR procedures. These loci were found to be highly polymorphic, with 13 to 30 alleles per locus in the three populations that we investigated ... more

Genetic diversity; Microsatellite; Molecular breeding; Popcorn; SSR locus; Zea mays

We analyzed genetic structure and diversity among eight populations of popcorn, using SSR loci as genetic markers. Our objectives were to select SSR loci that could be used to estimate genetic diversity within popcorn populations, and to analyze the genetic structure of promising populations with high levels of heterozygosity that could be used in breeding programs. Fifty-seven alleles (3 ... more

Control region; Genetic diversity; Genetic structure; Mitochondrial DNA; Setipinna taty

The genetic diversity of Setipinna taty, which is commercially fished in the China Sea, was studied based on mitochondrial DNA control region sequences. PCR was used to amplify the control region fragment in 100 individuals of S. taty collected from Weihai (WH), Yantai (YT), Zhoushan (ZS), Xiangshan (XS), and Ninghai (NH) in China. A control region fragment of 656 bp was ... more
