Major QTL QKL.sicau-AM-3B and QKW.sicau-AM-4B and their effects. (a): Genetic map of chromosome 3B; the green area was the interval of QKL.sicau-AM-3B; (b): effect of QKL.sicau-AM-3B shown as box plots calculated after grouping the AM population into two classes based on the flanking markers. Ailanmai and LM001 indicate the lines with and without positive alleles of QKL.sicau-AM-3B; (c): genetic map of chromosome 4B; The blue area was the interval of QKW.sicau-AM-4B; (d): effect of QKW.sicau-AM-4B shown as box plots calculated after grouping the AM population into two classes based on the flanking markers. CZ: Chongzhou; WJ: Wenjiang; YA: Ya’an; ^** significance at the 0.01 probability level, ^* significance at the 0.05 probability level. Differences between the two groups were labeled below the environmental names and BLUP
