Genetic diversity of orchardgrass germplasm detected by molecular markers

摘要

Orchardgrass( Dactylis glomerata L) is one of the most important grasses in temperate zones with high forage yield and good quality.In this study we investigated the genetic diversity in 60 orchardgrass accessions with a combination of three molecular markers : AFLP (Amplified fragment length polymorphism), ISSR ( Inter‐simple sequence repeat) and RAPD (Random amplified polymorphic DNA).
