The study of genetic diversity Dactylis glumerata ecotype using ISSR molecular marker

Cocksfoot (Dactylis glomerata) is a perennial grass that is used for pastures and hay production.Genetic variation for 15 ecotype were surveyed using the number of 20 ISSR primers, that the number of 12 primers can be scored. The ISSR primers can be produced the number of 90 bands, which the polymorphism was showed for the number of 67 bands. The primer of IS5 showed the highest number of band (12 bands) and IS7, IS12, IS10 and IS15 showed the lowest number of band (5 bands). The average of polymorphism percentage and polymorphism information content (PIC) between populations was 75.45% and 0.33 respectively. The highest polymorphism information content (PIC) was belonged to IS9 and IS10. Classification of cluster analysis showed that the ecotype were divided into 4 groups and the genetic diversity of the ecotype not matching with the geographical diversity, also the results of grouping by using analysis of coordinate analysis (PCo) were confirmed.
