Abstract
Italian ryegrass (Lolium multiflorum Lam.) cultivars vary widely in their persistence; there are very early heading annual types as well as very late heading, summer-survival types that survive for 2 or 3 years. Hybrid cultivars that survive in summer temperatures are bred using genes of a similar species (Festuca) in combination with Lolium. It is hypothesized that commercial summer-survival cultivars of Italian ryegrass include Festuca genome fragments. In this report, we investigated the genomic constitution of five summer-survival cultivars using the genomic in situ hybridization technique. Two out of the five cultivars contained Festuca genome fragments, confirming that summer-survival cultivars may include Festuca genome fragments.

期刊介绍：
Grassland Science is the official English language journal of the Japanese Society of Grassland Science. It publishes original research papers, review articles and short reports in all aspects of grassland science, with an aim of presenting and sharing knowledge, ideas and philosophies on better management and use of grasslands, forage crops and turf plants for both agricultural and non-agricultural purposes across the world. Contributions from anyone, non-members as well as members, are welcome in any of the following fields:
grassland environment, landscape, ecology and systems analysis;
pasture and lawn establishment, management and cultivation;
grassland utilization, animal management, behavior, nutrition and production;
forage conservation, processing, storage, utilization and nutritive value;
physiology, morphology, pathology and entomology of plants;
breeding and genetics;
physicochemical property of soil, soil animals and microorganisms and plant
nutrition;
economics in grassland systems.
