Quantitative Trait Loci for Natural Variation in Petal Shape and Size.

<p>The first two letters of the QTL name designate the parental lines from which the recombinant inbred lines were derived, C for Columbia, E for Estland-1, L for Landsberg <i>erecta</i>. Chr, the chromosome to which the QTl was mapped. LOD, likelihood of difference score. PVE, percentage of the variance explained (R2). CI, Confidence Interval. All petal trait measurements are normalized to comparable sepal data apart from petal shape, which is calculated as the ratio of petal length/petal width.
