aMeta-QTLs (GY for grain yield and ASI for anthesis-silking interval) followed by a chromosome number
bDetected QTLs by single QTL analysis in each population among different environments. The three populations were represented by the following order: pop1 (CML444 × Malawi), pop2 (CML440 × CML504) and pop3 (CML444 × CML441)
