Genetic diversity; Geographic distribution; Medicago; Phylogeny; Simple sequence repeat; Transferability

Six Medicago species were investigated to characterize and valorize plant genetic resources of pastoral interest in Morocco. Samples were obtained from the core collection of the South Australian Research and Development Institute (SARDI). The transferability of single sequence repeat markers of Medicago truncatula was successful with 97.6% efficiency across the five ... more

Genetic diversity; Germplasm characterization; Multivariate analysis; Saccharum spp

We evaluated the genetic diversity of 77 clones of sugarcane used in crosses made by the Brazilian interuniversity network for the development of the sugar/energy sector (RIDESA) breeding program. Characterization of the genotypes was carried out at the ratoon stage, based on eight morphological traits and seven agronomic traits. Diversity analysis was carried out beginning with the Ward ... more

Genetic diversity; Simple sequence repeats; Upland cotton

The genetic diversity of 51 upland cotton cultivars with different parental origins and breeding periods that were developed in Hubei Province was studied on the basis of 237 mapped simple sequence repeat markers covering the cotton genome. A total of 108 polymorphic primer pairs amplified 196 loci; the polymorphism information content range was 0.04 to 0.83, with an average of 0.46. A ... more

Cydonia oblonga Mill.; Genetic diversity; Quince; RAPD

Turkey has very rich quince genetic resources, and the country currently dominates world quince production. In particular, the northeastern part of the country has notable Cydonia oblonga Mill. germplasm. Authenticating the identity of germplasm resources of C. oblonga Mill. would be of great value for breeding practices. In the present study, genetic variations of 14 ... more

EST-SSR; Genetic diversity; SSR; Tomato varieties

The genetic diversity and relationship of 42 tomato varieties sourced from different geographic regions was examined with EST-SSR markers. The genetic diversity was between 0.18 and 0.77, with a mean of 0.49; the polymorphic information content ranged from 0.17 to 0.74, with a mean of 0.45. This indicates a fairly high degree of diversity among these tomato varieties. Based on the ... more

Genetic differentiation; Genetic diversity; Hatchery stock; Microsatellite; Ruditapes philippinarum; Wild population

Manila clam (Ruditapes philippinarum) is one of the major aquaculture species around the world and supports an important segment of the aquaculture industry in China. In this study, we used ten microsatellite markers to detect genetic diversity within six R. philippinarum populations and genetic differentiation between them. A total of 109 alleles were detected across ... more

Genetic diversity; Palm tree; Population management; Similarity coefficients

The purpose of this study was to analyze the effects of management on the genetic structure of natural populations of Attalea speciosa in the State of Piauí, Brazil, using random-amplified polymorphic DNA (RAPD) markers. Three babassu populations under different management systems were selected. Polymerase chain reactions were performed for 20 RAPD primers. A total of 146 bands ... more

Cultivar identification; Genetic diversity; Genetic similarity; ISSR; Olea europaea L.; SSR

The olive tree is an iconic tree of the Mediterranean, and is used extensively to produce high-quality olive oil. Although the China olive industry has just begun to be valued, there were also existed mislabeling and synonyms in introduced cultivars. The aim of this study was to analyze genetic similarities among olive cultivars in China using SSR and ISSR techniques. Thirty-two samples ... more

In order to investigate genetic diversity and population structure of Ceratoides arborescens, six populations were selected from different steppe types in Inner Mongolia grasslands of China. Inter-simple sequence repeat (ISSR) markers were used to assess the genetic diversity within and among natural populations of C. arborescens. Thirteen ISSR primers generated 154 ... more
