Abstract

Abstract:

Two genetic integrated maps of Populus adenopoda × P. albawere constructed using FsLinkageMap 2.0 and JoinMap 4.0 softwares in this study. On recombination ratio=0.245, two frame maps were all composed of 20 groups (containing more than 4 markers). There was significant difference in the map distances between two frame maps and the codominant marker order of the map constructed by JoinMap4.0 was more congruous with the Populus consensus map than that by FsLinkageMap2.0. The estimated genome length was 2 695.56 cM and covered 93.34% of the total length of the genome of Populus adenopoda × P. alba. Two maternal maps constructed with FsLinkageMap 2.0 and MapMaker 3.0 had thirty-two pairs of corresponding linkage groups which were built up with 113 common markers. The codominant marker order of the map constructed by FsLinkageMap2.0 was more coincident with the relative marker position in the poplar whole genome than that by MapMaker 3.0.
