Figure 2.

QTLs detected for starch (ST), Glc (GL), Fru (FR), and Suc (SU) contents in the Bay-0 × Shahdara population. Each QTL is represented by a bar located at its most probable position (likelihood peak). QTLs detected on N+ (respectively, N−) are represented on the left (resp. right) side of chromosomes. The length of the bar is proportional to the QTL contribution to the phenotypic variation in the population (R²). The sign of the allelic effect is indicated for each QTL. The framework genetic map (indicating positions of the microsatellites markers) is from Loudet et al. (2002).
