Salient features of the comparison between the A genome LGs of our tetraploid BC1 map and the diploid AA map published by Moretzsohn et al. (2005). The LGs from this study are named a01, a02, a10, a06, and a08. The LGs of Moretzohn's map (01A, 02A, 06A, 10A, 08A and 11A) are represented by a green bar. Common markers between corresponding LGs in the two maps are indicated in blue, underlined and connected with dashed lines. In the two maps the distances are given in Kosambi centimorgans.
