a
Aging treatments: ‘B’ and ‘R’ indicate BIL and RIL population, respectively. ‘A’, ‘N’, and ‘C’ denote artificial, natural, and combined aging treatment, respectively, ‘09’, ‘10’, ‘11’, and ‘12’ indicate 2009, 2010, 2011, and 2012, respectively.
b
QTL name: the letter ‘q’ stands for QTL and ‘SS’ for seed storability; the letter ‘n’ and ‘nj’ for rice cultivar N22 and Nanjing35, respectively; the first number denotes the chromosomal location; the second number denotes different QTL located on the same chromosome.
c
LOD score: logarithm of odds.
d
PVE (%): percentage of total phenotypic variance explained by the QTL.
