Genetic Variation of Seed Related Traits in Festuca arundinacea Using Multivariate Statistical Methods
Genetic diversity is the basis of breeding studies in many plant species and is one of the most important indicators for selecting parents. The aim of this experiment was to investigate the genetic diversity of tall fescue (Festuca arundinacea) using agronomic traits such as plant height, spring growth score, days to flowering, days to pollination, flag leaf length and width, panicle length, we...
متن کاملInterpolating Genetic Variation in Natural Populations: A Case Study of Plains Rough Fescue (Festuca hallii)
Characterization of individual genetic variation within a plant population is an important component of plant conservation and evolutionary genetics. Here we present a marker-based approach to interpolating individual genetic information from a sample of plants to the whole population. The effectiveness of the approach was demonstrated by applying AFLP markers to estimate genetic distinctivenes...
متن کاملGeographic Variation in Festuca rubra L. Ploidy Levels and Systemic Fungal Endophyte Frequencies
Polyploidy and symbiotic Epichloë fungal endophytes are common and heritable characteristics that can facilitate environmental range expansion in grasses. Here we examined geographic patterns of polyploidy and the frequency of fungal endophyte colonized plants in 29 Festuca rubra L. populations from eight geographic sites across latitudes from Spain to northernmost Finland and Greenland. Ploidy...
متن کاملIntraspecific DNA content variability in Festuca pallens on different geographical scales and ploidy levels.
BACKGROUND AND AIMS Intraspecific genome size variability of Festuca pallens occurring on relict rocky steppes in Central Europe was studied on two ploidy levels and three geographical scales: (1) local scale of 24 populations, (2) landscape scale of three transects in river canyons or hill systems, and (3) global scale of 160 samples covering the whole distribution area. METHODS DAPI flow cy...
متن کاملVariation and genetic structure of Tunisian Festuca arundinacea populations based on inter-simple sequence repeat pattern.
Tunisian tall fescue (Festuca arundinacea Schreb.) is an important grass for forages or soil conservation, particularly in marginal sites. Inter-simple sequence repeats were used to estimate genetic diversity within and among 8 natural populations and 1 cultivar from Northern Tunisia. A total of 181 polymorphic inter-simple sequence repeat markers were generated using 7 primers. Shannon's index...
