Efficiency of morphological and RAPD markers in evaluation of red clover changes caused by natural selection

The study was conducted to determine the efficiency of morphological and RAPD markers in evaluation of changes in three red clover (Trifolium pratense L.) cultivars caused by three years of growing in an upland region.Number of markers detected, values and ranges of distances calculated and 2D Principal Coordinate Analyses (2D PCoA) based on both marker techniques were compared.Although both marker methods indicated the differences among cultivars and selections, parameters differed in values and informativeness.<the number of loci detected by RAPD markers was much higher than that determined with morphological traits.The values and ranges of morphological distances were higher and wider than those of molecular distances. The eigenvectors of 2D PCoA based on morphological data explained more of the total variation observed in the whole data set.Each of the data sets provided different types of information and the use of both methods may be a suitable approach to improve prediction of genetic changes in red clover.
