Abstract


Two different phenotypes have been observed with regard to fruit hairiness in Centranthus calcitrapaethroughout the Iberian Península, Baleario Island and France: hirsute and glabrous fruits. In this paper the inheritance of this character in two Andalusian populations has been inferredby using artificial crossings. It has been shown that fruit hairiness is based on a simple two-allele mendelian locus being hairiness dominant over the recessive glabrous fruits. Therefore,this character should not be used for separation of taxa.
