were detected that explained 5–6 % of the total
variation. The QTL that explained the most
variation was that for stem color, which was
detected in the same region of chromosome 2 for
both years (Fig.22.3).“LegumeBase”contains
an interactive database for selecting LjMG RILs
based on the 13 phenotypic traits evaluated by
Gondo et al. ( 2007 ). Moreover, macrosynteny
between soybean andL. japonicuswas analyzed
with the objective of applying the genomic
information of the model legumeL. japonicusto
soybean (Tsubokura et al. 2008 ). In addition, two
other kinds of RILs were deposited from Aarhus
University, Denmark. The first RIL is from
crosses betweenL. japonicus“Gifu B-129”and
L. burttii“B-303”(G×LB population) (SandalFig. 22.1 Habitat of the two Lotus genera (Lotus
