ASSOCIATION BETWEEN QUANTITATIVE TRAITS AND ALLOZYME HETEROZYGOSITY IN A TETRASOMIC SPECIES: DACTYLIS GLOMERATA

Diversity and Relationships of Yield and Quality Traits in Cocksfoot (Dactylis glomerata L.) Genotypes

Cocksfoot (Dactylis glomerata L.) is an important cool season grass species in the moderate climate of Iran. In order to evaluate the yield and quality traits, an experiment was conducted in irrigation conditions using 36 accessions of Dactylis glomerata using a randomized complete block design with three replications in Islamabad, Kermanshah province, Iran in 2010. Characters such as forage dr...

Genetic 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...

Increased Meiotic Irregularity Accompanying Inbreeding in Dactylis Glomerata L.

Fungal Diversity The endophytic mycobiota of the grass Dactylis glomerata

Fungal endophytes were isolated from asymptomatic and symptomatic plants of Dactylis glomerata sampled in different ecosystems in Spain. Fungi were identified using morphological, as well as molecular methods based on internal transcribed spacer (ITS) and ribosomal DNA sequencing. Molecular data provided a framework for identification and assessing the phylogenetic position of isolates. One hun...

Divergence and variation of quantitative traits between allozyme genotypes of Avena barbata from contrasting habitats

1 Avena barbata occurs as two multilocus allozyme genotypes associated with moist (mesic) and dry (xeric) habitats in California. We examined the divergence of quantitative traits between these genotypes, and heritable trait variation in the progeny of a cross. 2 A replacement series showed that the mesic genotype was competitively superior to the xeric. Early germination could alter this compe...
