Abstract

Three genetic similarity coefficients were estimated and compared for their usefulness: simple matching (SSM), Jaccard’s (SJ) and Dice’s (SD), all based on dominant markers data from individuals representing predominantly self-pollinating species. AFLP markers were used to analyze 139 Phaseolus vulgaris L. (common bean) and 67 Lactuca saligna L. (least lettuce) accessions, and RAPD markers were used to analyze 110 Triticum dicoccoides Koern. (wild emmer wheat) accessions. Similar discriminating structure and power based on the three genetic similarity coefficients was found for each of the three species. This discriminating power was high for both P. vulgaris and L. saligna but moderate for T. dicoccoides. With closely related individuals, as in our study, the absence of a band in two individuals should be due to an identical cause inherited from the same ancestor. Accordingly we propose the use of SSM, which alone out of the three examined coefficients involved shared absence of DNA bands, as contributing to genetic similarity. When RAPDs are employed, inferences about population structure and nucleotide divergence should be made with prudence as the nature of genetic variation uncovered by RAPDs is often unclear.
