SYSTEMATIC STUDY OF SECALE CEREALE IN IRAN
Secale cereale (rye) with its vitally importance can have a marked place in the world cereal production, particularly in North Europe. This study concerns morphology, taxonomy and cytotaxonomy of this species in Iran. Based on the evaluation of 12 qualitative and quantitative morphological characters and using phenetic analysis, it was revealed that, S. cereale occurs in Iran with two subspecie...
متن کاملA Cytogenetic Analysis of the Hybrid Secale Cereale L. x Secale Montanum Guss. and Its Progeny.
ITHIN the genus Secale L. hybrids between various perennial forms have all shown regular meiotic chromosome behavior as have hybrids between different annual strains belonging to S. cereale L. In all hybrids between S. cereale and perennial forms, however, a translocation figure has been observed a t metaphase I in the PMC’s. The maximum association is apparently a ring-of-six, but this is seld...
متن کاملACREMONIUM-ENDOPHYTES OF PERENNIAL RYEGRASS (Lolium perenne) IN FRANCE
13-17 ABSTRACT Infection with endophytic fungi (Acremonium spp.) was detected in seeds of wild populations of perennial ryegrass (Lolium perenne) collected in France by private breeding companies and INRA. In total, 262 populations were examined and 70% contained Acremonium. It is worth noticing that most populations are endophyte infected but generally endophyte infection rates per population ...
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 کاملTowards a whole-genome sequence for rye (Secale cereale L.).
We report on a whole-genome draft sequence of rye (Secale cereale L.). Rye is a diploid Triticeae species closely related to wheat and barley, and an important crop for food and feed in Central and Eastern Europe. Through whole-genome shotgun sequencing of the 7.9-Gbp genome of the winter rye inbred line Lo7 we obtained a de novo assembly represented by 1.29 million scaffolds covering a total l...
