  1. Env, environment; HKW, one-hundred kernel weight; KL, kernel length; KT, kernel thickness; KW, kernel width; 07BJ, year 2007 Beijing; 07HN, year 2007 Hainan; 08HN, year 2008 Hainan
  2. 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
  3. b Significant probabilities
  4. 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
