The European Search Catalogue for Plant Genetic Resources, EURISCO, provides information about 1.8 million crop plant accessions preserved by almost 400 institutes in Europe and beyond. EURISCO is being maintained on behalf of the Cooperative Programme Resources. It based a network National Inventories 43 member countries represents an important effort preservation world's agrobiological diversity providing large genetic kept collaborating collections. Moreover, also assists its fulfilling...

The German Federal ex situ Genebank of Agricultural and Horticultural Crop Species is the largest collection its kind in countries European Union amongst 10 collections worldwide. Beside enormous scientific value as a safeguard plant biodiversity, genetic resources maintained are also high importance for breeders to provide new impulses. complex processes managing such supported by Information System (GBIS). GBIS an important source information researchers breeders, e.g. identifying...

The need for higher yielding and better-adapted crop plants feeding the world's rapidly growing population has raised question of how to systematically utilize large genebank collections with their wide range largely untouched genetic diversity. Phenotypic data that been recorded decades during various rounds seed multiplication provides a rich source information. Their usefulness remained limited though, due biases induced by conservation management over time or changing environmental...

We present a comprehensive survey of cytogenetic and genomic diversity the GGAtAt genepool wheat, thereby unlocking these plant genetic resources for wheat improvement. Wheat yields are stagnating around world new sources genes resistance or tolerances to abiotic traits required. In this context, tetraploid wild relatives among key candidates Despite its potential huge value breeding, is largely neglected. Understanding population structure, native distribution range, intraspecific variation...

To facilitate the updating of in situ and ex conservation strategies for wild taxa genus Hordeum L., a combined ecogeographic survey gap analysis was undertaken. The based on Global Inventory Barley Plant Genetic Resources held by ICARDA plus additional datasets, resulting database containing 17,131 accessions. concluded that genetic reserve should be established Mendoza Province Argentina, as this is most species-rich area globally . A network reserves also set up across Fertile Crescent...

Relatively few studies have extensively analysed the genetic diversity of runner bean through molecular markers. Here, we used six chloroplast microsatellites (cpSSRs) to investigate cytoplasmic 331 European domesticated accessions scarlet (Phaseolus coccineus L.), including botanical varieties albiflorus, bicolor and coccineus, a sample 49 wild from Mesoamerica. We further explored pattern landraces using 12 phenotypic traits on 262 individuals. For 158 accessions, studied relationships...

Emmer wheat, Triticum dicoccon schrank (syn. T. dicoccum (schrank) schÜbl.), is one of the earliest domesticated crops, harboring a wide range genetic diversity and agronomically valuable traits. The crop, however, currently largely neglected. We provide wealth karyotypic information from comprehensive collection emmer wheat related taxa. In addition to C-banding polymorphisms, we identified 43 variants chromosomal rearrangements in dicoccon; among them 26 (60.4%) were novel. T7A:5B...

Wild Triticum and Aegilops species are increasingly used in wheat breeding programmes around the world as donors of genes conferring resistance to biotic abiotic stresses, well that contribute improvement grain quality. In present study, thirty-nine accessions diploid with A genome (Triticum boeoticum T. urartu) were evaluated for presence powdery mildew (Blumeria graminis) leaf rust (Puccinia recondita) using both inoculation tests sequence tagged sites (STS) marker analyses order find...

Darwin Core (DwC) defines a standard set of terms to describe the primary biodiversity data. Primary data are records derived from direct observation species occurrences in nature or describing specimens biological collections.
