Phylogenetic Relationships in the Festuca-Lolium Complex (Loliinae; Poaceae): New Insights from Chloroplast Sequences
The species within the Lolium/Festuca grass complex have dispersed and colonized large areas of temperate global grasslands both naturally and by human intervention. The species within this grass complex represent some of the most important grass species both for amenity and agricultural use worldwide. There has been renewed interest by grass breeders in producing hybrid combinations between th...
متن کاملUse of Flow Cytometer in Breeding Festuca X Lolium Hybrids
4-97 ABSTRACT Ploidy in various generic Lolium Festuca progenies were assessed by flow cytometry and compared to conventional chromosome counting. In non-segregating triploid and tetraploid progenies, the cytometer estimated so accurately the level of plant ploidy that chromosomes counting would be no use. In segregant progenies, all the tetraploid plants according to the cytometer had effectiv...
متن کاملارزیابی روابط خویشاوندی کمپلکس Festuca-Lolium در ایران با استفاده از ردیف‌خوانی ناحیه بین ژنی trnH-psbA ژنوم کلروپلاستی
کمپلکس Festuca-Lolium به گروهی از آرایه‌های دارای خویشاوندی نزدیک در دودمان Festuca و خویشاوندان آن گفته می‌شود که در بر گیرنده گونه‌هایی از دو جنس Lolium و Festuca است. اعضای این کمپلکس را گونه‌های دگرگشن جنس Lolium و گونه‌های زیرجنس Schedonorus از جنس Festuca تشکیل می‌دهند. در پژوهش حاضر، با استفاده از ترادف های نوکلئوتیدی ناحیه trnH-psbA ژنوم کلروپلاستی، روابط 6 گونه متعلق به این کمپلکس در ا...
متن کاملGenetic relationships between Lolium (Poaceae) species revealed by RAPD markers.
The genus Lolium is one of the most important groupings of temperate forage grasses, including about eight recognized species that are native to some temperate and subtropical regions of the northern hemisphere. We examined genetic relationships among 18 accessions representing all Lolium species using RAPD markers. Among 50 random primers that we screened, 13 gave reproducible amplification ba...
متن کاملForage grasses with lower uptake of caesium and strontium could provide ‘safer’ crops for radiologically contaminated areas
Substitution of a species or cultivar with higher uptake of an element by one with lower uptake has been proposed as a remediation strategy following accidental releases of radioactivity. However, despite the importance of pasture systems for radiological dose, species/cultivar substitution has not been thoroughly investigated for forage grasses. 397 cultivars from four forage grass species; hy...
