Limited genetic changes observed during in situ and ex situ conservation in Nordic populations of red clover (Trifolium pratense).

ABSTRACT:

Introduction

In situ and ex situ conservation are the two main approaches for preserving genetic diversity. The advantages and disadvantages of the two approaches have been discussed but their genetic effects have not been fully evaluated.

Methods

In this study we investigate the effects of the two conservation approaches on genetic diversity in red clover. Seed samples collected from wild populations in Sweden and Norway in 1980, their subsequent generations created during seed regeneration at the gene bank and samples recollected from the same location as the original samples, were analyzed with microsatellite markers, alongside reference samples from cultivars.

Results

Overall, there was a differentiation between cultivars and the wild material and be
