Fig. 7From: Characterization of a wheat stable QTL for spike length and its genetic effects on yield-related traitsMeta-QTL and QTL clusters for spike-related traits on chromosome 2B reported in recent years. The figures a and b represent MQTL reported by Saini et al. [52] and Yang et al. [53], respectively. Figure c represents the QTL clusters reported by Zhang et al. [54]. The red segment on the three chromosomes is qSl-2B in the figureBack to article page
