Identification of orchardgrass (Dactylis glomerata L.) cultivars by using simple sequence repeat markers.
The accurate identification of orchardgrass (Dactylis glomerata L.) cultivars is necessary to ensure purity for consumers, the effective utilization of cultivars, and to protect the intellectual property for breeders. Therefore, this study aimed to use SSR to construct DNA fingerprinting of orchardgrass cultivars. The genetic diversity of 32 orchardgrass cultivars originated from 21 countries, ...
متن کاملIn vitro SCREENING FOR RESISTANCE TO PROLINE ANALOGUES IN ORCHARDGRASS Dactylis glomerata L
Plant regeneration capacity of orchardgrass leaf explants cultured in vitro in the presence of 0.01, 0.1, 1.0 and 10.0mM hydroxyproline (Hyp) or azetidin-2-carboxylic acid (A2CA) was determined. Hyp inhibited to a lower extent than A2CA formation of somatic embryos, respectively plants. Hyp also induced relatively insignificant changes of free amino acid content in the leaves of the regenerants...
متن کاملAnalysis of diversity and relationships among orchardgrass (Dactylis glomerata L.) accessions using start codon-targeted markers.
Orchardgrass, or cocksfoot, is an important perennial forage grass worldwide. The comprehensive understanding of orchardgrass accessions will benefit germplasm collection and breeding progress, and it will enhance efforts to improve forage yield and quality. Therefore, 24 novel, simple, polymorphic, and reliable start codon-targeted (SCoT) markers were used to analyze the diversity and genetic ...
متن کاملGenetic variation and comparison of orchardgrass (Dactylis glomerata L.) cultivars and wild accessions as revealed by SSR markers.
Orchardgrass is a highly variable, perennial forage grass that is cultivated throughout temperate and subtropical regions of the world. Despite its economic importance, the genetic relationship and distance among and within cultivars are largely unknown but would be of great interest for breeding programs. We investigated the molecular variation and structure of cultivar populations, comp...
متن کاملGenetic Diversity and Association of EST-SSR and SCoT Markers with Rust Traits in Orchardgrass (Dactylis glomerata L.).
Orchardgrass (Dactylis glomerata L.), is a well-known perennial forage species; however, rust diseases have caused a noticeable reduction in the quality and production of orchardgrass. In this study, genetic diversity was assessed and the marker-trait associations for rust were examined using 18 EST-SSR and 21 SCoT markers in 75 orchardgrass accessions. A high level of genetic diversity was det...
