title: AFLP analysis of the diversity and phylogeny of Lens and its comparison with RAPD analysis.
abstract: AFLP and RAPD marker techniques have been used to evaluate and study the diversity and phylogeny of 54 lentil accessions representing six populations of cultivated lentil and its wild relatives. Four AFLP primer combinations revealed 23, 25, 52 and 48 AFLPs respectively, which were used to partition variation within and among Lens taxa. The results of AFLP analysis is compared to previous RAPD analysis of the same material. The two methods provide similar conclusions as far as the phylogeny of Lens is concerned. The AFLP technique detected a much higher level of polymorphyism than the RAPD analysis. The use of 148 AFLPs arising from four primer combinations was able to discriminate between genotypes which could not be distinguished using 88 RAPDs. The level of variation detected within the cultivated lentil with AFLP analysis indicates that it may be a more efficient marker technology than RAPD analysis for the construction of genetic linkage maps between carefully chosen cultivated lentil accessions.
