Plant height,ear height,ear length,ear diameter,tassel branch number,date to silk and date to pollen shedding are important agronomical traits in maize.In this study,apopulation of 141 RIL lines was used to map quantitative trait locus(QTL)of seven agronomic traits under three different environments.A total of 18 QTLs associated with the seven traits were detected.Individual locus explained9.79%to 37.35% of phenotypic variance.Four of them were detected under more than one environment,and 5QTLs were the sam...
