QTL Analysis for Plant Height and Leaf Angle by Using Different Populations of Maize

Yu Li

Abstract

Quantitative trait loci(QTL) analysis for some important agronomic traits(plant height,ear height and leaf angle) were carried out,using SSR markers and three F2:3 populations(H21×Mo17,Zi330×K36 and B73×L050) in order to understand the genetic and molecular mechanisms of these traits.Eighteen QTL were detected for plant height,twelve QTL for ear height and nine QTL for leaf angle.Some of these QTL were located within the same chromosome regions,and the peaks of some QTL regions overlaid.In addition,it was found that some QTL were located in the same regions with known qualitative genetic loci affecting these traits.
