Methodology of alfalfa breeding: A review of recent achievements
Résumé
In this paper, we review achievements recently reported in methodology of alfalfa breeding, with a focus on breeding criteria, mainly for forage quality and resistance to stress, and methodology, with a special concern to characterisation and management of genetic resources. A major part of the paper is dedicated to progresses in molecular biology. Thanks to the vicinity to the model species Medicago truncatula, genomic databases, knowledge and tools were developed. In the same time, theoretical developments were made for development of linkage maps for autotetraploid species. As a result, QTLs are located for an increasing number of traits. Candidate genes will be shortly identified. The possible applications of these advances are discussed, especially as they could provide new insights into the functioning of alfalfa canopies, that are complex because of the genetic diversity and of the complex physical structure. Recent achievements in transgenesis are also described.
