a The numbers indicate the number of deleted nucleotides, and the letters indicate nucleotides. Numbers and letters in bold indicate the favourable alleles with the exception of the S1865/07BJ-KL association
b Significant probabilities
c The allele of inbred lines Zong3 and 87-1 which were used to develop an IF2 population for QTL mapping [40,41]. Letters and numbers in bold indicate the favourable alleles
