Gene mapping for a Cupressus species is presented for the first time. Two linkage maps for the Mediterranean cypress (Cupressus sempervirens) varieties, C. sempervirens var. horizontalis and C. sempervirens var. pyramidalis, were constructed following the pseudo-testcross mapping strategy and employing RAPD, SCAR and morphological markers. A total of 427 loci (425 RAPDs, two SCARs) repres...
