Abstract

A F2:9 RIL(recombinant inbred line) population with 122 lines was derived from a cross of 'Hefeng 25' as a female parent and 'Xinmin 6' as a male parent.A new soybean molecular genetic map was constructed by using Mapmaker.The new soybean genetic map covered 2 348.3 cM,and the average distance among markers was 18.3 cM.The length of linkage group varied from 15.1 cM to 195.9 cM,and the markers on each linkage group varied from 2 to 10.124 SSRs,1 EST and 3 morphology markers were located in this map.A pubescence color(Pb) gene was located on LG06-C2 linkage group,39.6 cM far from the marker of Sat_402.The auricle color gene(Le) and flower color gene(W) were located on LG12-F linkage group,the distance between Le and W was 9.9 cM,the distances between the two genes and the markers of Satt348 and Sat_240 were 13.3 cM and 10.5 cM,respectively.
