Physical and genetic mapping in the grasses Lolium perenne and Festuca pratensis.
A single chromosome of the grass species Festuca pratensis has been introgressed into Lolium perenne to produce a diploid monosomic substitution line 2n = 2x = 14. In this line recombination occurs throughout the length of the F. pratensis/L. perenne bivalent. The F. pratensis chromosome and recombinants between it and its L. perenne homeologue can be visualized using genomic in situ hybridizat...
متن کاملA demonstration of a 1:1 correspondence between chiasma frequency and recombination using a Lolium perenne/Festuca pratensis substitution.
A single chromosome of the grass species Festuca pratensis has been introgressed into Lolium perenne to produce a diploid monosomic substitution line 2n = 2x = 14. The chromatin of F. pratensis and L. perenne can be distinguished by genomic in situ hybridization (GISH), and it is therefore possible to visualize the substituted F. pratensis chromosome in the L. perenne background and to study ch...
متن کاملکارایی نشانگر مولکولی SCoT در بررسی تمایز دو گونه Lolium perenne و Lolium multiflorum
چچم یکی از گیاهان مهم علوفهای در مناطق سردسیری جهان میباشد و در شرایط مختلف آب و هوایی رشد میکند. تنوع ژنتیکی دو گونه بین نه ژنوتیپ از Lolium perenne و نه ژنوتیپ از Lolium multiflorum با استفاده از 15 نشانگر مولکولی SCoT بررسی شد. آغازگرهای ScoT در مجموع 86 باند تولید کردند که از این تعداد 12 باند یکشکل مشاهده شد و سایر باندها چندشکل بودند. آغازگرهای SC35، SC36 و SC26 بهترتیب با 9 و 8 ب...
متن کاملImplementation of Genomic Prediction in Lolium perenne (L.) Breeding Populations
Perennial ryegrass (Lolium perenne L.) is one of the most widely grown forage grasses in temperate agriculture. In order to maintain and increase its usage as forage in livestock agriculture, there is a continued need for improvement in biomass yield, quality, disease resistance, and seed yield. Genetic gain for traits such as biomass yield has been relatively modest. This has been attributed t...
متن کاملComparison of early development of three grasses: Lolium perenne, Agrostis stolonifera and Poa pratensis.
BACKGROUND AND AIMS To improve the management of grass communities, early plant development was compared in three species with contrasting growth forms, a caespitose (Lolium perenne), a rhizomatous (Poa pratensis) and a caespitose-stoloniferous species (Agrostis stolonifera). METHODS Isolated seedlings were grown in a glasshouse without trophic constraints for 37 d (761 degrees Cd). The appea...
