EFICIENȚA UNOR MARCHERI MOLECULARI ÎN DISCRIMINAREA POPULAȚIILOR DE LUPOAIE ORIGINARE DIN CHINA

Abstract

In this study, the effectiveness of different types of molecular markers in assessing genetic diversity of populations of O. cumana from China was determined. ISSR and SSR markers detected different levels of genetic variability among and within broomrape populations. SSR markers analysis showed high level of genetic variation within the populations as revealed by high average values of Nei's gene diversity (H=0,75) and Shannon's information index (I=1,44), while genotyping with ISSR markers showed greater ability to discriminate genotypes according to Resolving power (Rp=7,24). Thus, the combined use of ISSR and SSR markers allowed the detection of higher polymorphism than either set of marker alone.
