betweenL. japonicus“Gifu B-129”andL.fili-

caulis“B-37”(G×F population) (Sandal et al.

2002 , 2009 ). Both of these RILs will be available

from “LegumeBase” in the near future

(Table22.1). Please refer to Chap. 4 of this book

for more detailed information about the RILs

described above.

Fig. 22.2 Population structures estimated by STRUC-

TURE analysis at K = 9 using data for 25 nuclear genetic

loci (Kai et al. 2010 ). The analysis was designed to

produce an admixture ancestry model, assuming no

correlations, with a burn-in length of 10^5 and a run length

of 10^6 iterations. Each accession is represented by a single

vertical bar partitioned into nine colored segments that

represent the accession’s estimated ancestry proportion.

Fig. 22.3 Molecular linkage map ofL. japonicusand the
location of QTLs identified for 13 agronomic traits in
2004 and 2005 (Gondo et al. 2007 ). Arrowheads indicate
the positions of QTLs and the key to symbols is
summarized in the box. The arrowheads to the left (blue)
and right (red) of each chromosome show the QTLs

detected in 2004 and 2005, respectively.FTflowering
